RFreq™ Q&A

Q:   I'm looking for the frequency information on digital channels.  Isn't analog dead?  Why do you have analog information?
A:

RFreq™ lists channel band edges, center frequency and legacy analog visual and carrier frequencies.  Typically when referring to digital TV broadcasts in 8VSB or digital CATV QAM channels, the center frequencies are used.  This app is for frequency referencing only, and requires the user to know what the source is.  The digital transition (ie. the death of analog) primarily refers to when full power TV stations moved to digital broadcasts in 2009, or the fact that large CATV plants are moving toward all digital.  However, as things are still changing, and for many niche/legacy applications where analog is still being used (like low power and translator broadcasts; businesses and schools CATV ...), it is helpful to technical personnel to have easy access to all of the frequency information (which is why we developed RFreq™).

Ask An Engineer

Q: Encoders - AV10E-QAM / SD10E-QAM - Is the unit’s software field upgradable?
A:

No, these units can only be upgraded at the factory.

Q: Encoders - HD264-2S-IP (6396) - The encoder does not always boot up properly when first powered up.
A:

Verify if the software version on the unit is 1.0.2 or below. If so update the software version to 1.0.3 (available since 11/2012).

Q: Encoders - HDE-2H/2S-QAM (6379) - The EAS feature is not working properly.
A:

A small lot of units during early production were mis-wired resulting in the EAS feature not working correctly. The affected encoders will not switch to EAS when triggered by a voltage input. With multiple units daisy-chained and a dry contact closure trigger, they remained locked on the EAS input after the EAS trigger was removed. These units should be returned to our Service Department to correct.

Q: Encoders - HDE-2H/2S-QAM, HDE-4S-QAM, HDE-CHV-QAM, & HDE-CSV-QAM - Why can’t I get my TV’s to lock to the QAM output for my encoder?
A:

Verify the following settings under the “QAM” tab:
1. Output Control is “ON”.
2. CW Control is not checked.
3. Output Channel /Frequency is selected.
4. Final Output Level is set appropriately based on system requirements.

Verify the following setting under the “TS Config” tab:
Multiplexed MPTS Output Configuration > TS Bitrate - “QAM Modulator” must be selected.

Q: Encoders - HDE-2H/2S-QAM / HDE-4S-QAM - The unit I just got allows me to have a Composite video input but my older unit does not have this option on the “Main > Video” screen.
A:

This is a recently added feature and is available with firmware version 1.0.15 or later (available since 08/12/2013). The RCA connector marked “Y” can be used for Composite Video input. Please check the Latest Software section of Blonder Tongue’s website for the latest released firmware and features.

Q: Encoders - HDE-2H/2S-QAM / HDE-4S-QAM - When setting up the unit, I see tiling issue on the output when I am using any of the inputs Component #1, Component #2, HD-SDI #1 or HDMI #1. The tiling disappears after the unit has been up and running for some time.
A:

Update firmware to any version later than 1.0.3 (available since 6/14/12)

Q: Encoders - HDE-2H/2S-QAM / HDE-4S-QAM - I cannot see the QAM output even though I have turned the “Output Control” ON on the “Main > QAM” screen and have selected the QAM RF channel number on the “Main > Output” screen.
A:

Ensure “QAM Modulator” option has been selected under “TS Bitrate” on the “Main > QAM” screen

Q: Encoders - HDE-2H/2S-QAM / HDE-4S-QAM - Some of my TV sets, set-top boxes or other digital demodulators are not picking up the QAM output of the HDE-4S-QAM (or HDE-2H/2S-QAM), yet the majority of devices on my system are working just fine.
A:

Here are a few of the units we found that will not work with standard QAM; Extron ATV 200 HD tuner, Contemporary Research 232-ATSC (the newer 232-ATSC+ works fine), some Sansui TV sets, & Digital stream DCS1000 Digital Cable STB.

Some devices will only recognize inverted QAM signals, check the software version of the DDQ module. IF the version is 1.7 then the QAM out is normal, if version 5.7 then the QAM is inverted. Contact Blonder Tongue technical support for additional help and for the upgrade files.

Q: Encoders - HDE-2H/2S-QAM / HDE-4S-QAM - I have SDI inputs without embedded Audio. Will your unit allow me to add audio to my existing SDI input?
A:

Yes, both the HDE-2H/2S-QAM and HDE-4S-QAM allows the user to add audio from one of the other inputs (analog audio, digital audio or audio from the HDMI input). The unit allows the mixing of any of the audio and video inputs.

Q: Encoders - HDE-2H/2S-QAM / HDE-4S-QAM - Is the unit capable of adding a second audio (example if incoming source is HD-SDI with embedded audio, can another audio be added through the component audio connections or other audio input?
A:

No, the unit cannot add two different audio sources together. It can take the audio from any of its input sources and embed them with any of its video inputs, but only one audio source can be embedded at a time.

The unit can pass multiple audio channels, if they are already embedded on the SDI input stream.

Q: Encoders - HDE-2H/2S-QAM, HDE-4S-QAM, HDE-2C-QAM & HDE-2H-QAM - If there is no input connected or to your encoder, what can I expect on the output QAM?
A:

The units will internally generate color bars (720p @ 60fps).

Q: Encoders - HDE-4S-QAM (6374) - I have 2 HDE-4S-QAM units and one has a software 1.0.13 and the other has a 1.0.13g, what is the difference?
A:

The newer HDE-4S-QAM units had a physical parts change, the g indicates that the unit has one IC verses another, this helps us track the different units.

Q: Encoders - HDE-4S-QAM (6374) - When I view the Audio and Video LEDs from one side they appear GREEN, when I view then from the other side they appear AMBER. Which is the correct state?
A:

The LEDs used in this product will appear to be a different color when viewed from one side or the other.

The correct way is to look straight/ head-on at the LEDs from the front. The LEDs status would be displayed as below:

 

   Audio LED

            Green = Audio input type detected is Analog (L/R)

            Amber = Audio input type detected is Digital Audio (PCM)

            Red = Audio input with error

            Off = Audio input not detected

 

   Video LED

            Green = Video input type detected is Component (YPbPr)

            Amber = Video input type detected is HDMI or HD-SDI

            Red = Video input with error

            Off = Video input not detected

 

However, software revision 1.0.12 or later corrects this issue by changing the LED indicator status:

   Audio LED

Green = Audio input type detected is Analog (L/R)

Green Blinking On/Off = Audio input type detected is Digital Audio (PCM)

Red = Audio input with error

Off = Audio input not detected

   Video LED

Green = Video input type detected is Component (YPbPr)

Green Blinking On/Off = Video input type detected is HDMI or HD-SDI

Red = Video input with error

Off = Video input not detected

Q: Encoders - HDE-CHV-QAM - When using a 1080p input source, why do I have picture issues?
A:

The unit is not designed to work with a 1080p input source. The inputs formats supported are: 480i, 720p, & 1080i.

Q: Encoders - HDE-CHV-QAM - When I use the IP Reset button, why doesn’t the encoder go back to the default setting?
A:

To reset the IP address to the default address, the unit must be powered up and the reset button held in for at least 10 seconds. This helps prevent accidental resets from momentary button taps.

Q: Encoders - HDE-QAM - My picture will drop out or I may just lose color after the device has been running for a while.
A:

The source device connected to the HDE-ASI may have lost its DTCP communication. This can be corrected by unplugging the HDMI cable then resetting it. If that does not work then power cycle the device connected to the HDE-ASI. This is a HDCP communication issue that is more prevalent on some consumer devices than others.

Q: Digital CATV - AP-60-860A - Will the AP-60-860A process 8VSB input to 8VSB output?
A:

No, the AP-60-860A has three operating modes.
i. Analog input to Analog Output
ii. QAM input to QAM Output
iii. QAM/8VSB input to Analog Output

Q: Digital CATV - AQD - Will the AQD pass all programs from the off-air channel?
A:

No, the AQD will pass only ONE program from the selected RF channel, not the entire channel.

Q: Digital CATV - AQD - Is the AQD compliant with SCTE 127? TV Guide requires the host station to be SCTE 127 compliant in order to do “VBI in MPEG”.
A:

If the source contains the XDS data (TV Guide Information) in CEA 608 format, then the AQD software will pass the information on line 21. This means the decoder will extract and insert VBI with the Closed Captioning data. However, if the Guide data is embedded in the PSIP tables, then the AQD will not pass that data. Regarding Closed Captioning: AQD supports both the SCTE20 (608) and 608-in-708 captions. AQD has not been tested through Cable labs for SCTE 127 compliance.

Q: Digital CATV - AQD - How is the CC (Closed Captioning) handled by DAP/AQD?
A:

When the CC option is enabled in DAP/AQD, then the CC, if present, will be displayed on the TV, PROVIDED THAT the TV itself is enabled for CC. If TV is disabled, no CC will be displayed. Conversely, if the CC option is disabled in DAP/AQD, regardless of whether the TV is enabled or disabled, the CC will not be displayed on the TV.

Q: Digital CATV - AQD & AQD-PCM - Will the AQD-PCM damage the AQT if it is mistakenly plugged in to it?
A:

Yes, the pin-outs on the connectors are different for pins 8 and 9, and will cause damage if the AQT module is plugged into the AQD-PCM.

Q: Digital CATV - AQM - Does the AQM perform remapping of PIDs?
A:

No, the AQM does not remap PIDs. You cannot make any changes to PSIP values either, all of this must be done with the ASI stream before the AQM.

Q: Digital CATV - AQM - I have a rack of AQM units that work while set in “normal” mode, while all the other QAM output units in the same system must be set to “inverted” mode for my set-top boxes and TV’s to lock on. Why is this?
A:

When the AQM is set to “inverted” or “normal” via the LCD front panel controls, it is referring to the internal QAM IF. During the IF up-conversion process to generate the output channel, the QAM channel gets inverted again. So the “inverted” IF turns to a “normal” QAM channel and the “normal” IF setting turns to an “inverted” QAM. So when the AQM is set to standard, the QAM output is “inverted” and when the unit is set to “inverted”, the QAM output is “normal”.

Q: Digital CATV - AQT - I have both AQT version 5.5 and AQT-PCM 3.3, but still have issue locking to QAM at all time.
A:

In the normal mode, the AQT will perform packet processing which if the input clock rate is higher than the output clock rate then the QAM may not lock at all times. “PASSTHRU” mode will resolve this issue by simply passing through the input signal to the output QAM block of the AQT. Refer to the updated manual for detail description of these. modes

Q: Digital CATV - AQT - I powered the chassis off and swapped some modules. When I powered the unit back on, the LED was solid ON, but the freq 000.
A:

Make sure the Power/data cable is plugged in securely, if this connector is 3/4 way then you could get “000” for frequency since the Control module is unsuccessful in trying to read the status of the module because the socket/pin is not connected correctly.

Q: Digital CATV - DAP - How is the CC (Closed Captioning) handled by DAP/AQD?
A:

When the CC option is enabled in DAP/AQD, then the CC, if present, will be displayed on the TV, PROVIDED THAT the TV itself is enabled for CC. If TV is disabled, no CC will be displayed. Conversely, if the CC option is disabled in DAP/AQD, regardless of whether the TV is enabled or disabled, the CC will not be displayed on the TV.

Q: Digital CATV - DAP - Will the embedded guide information from the digital broadcaster be present in the DAP’s Analog RF output?
A:

No.

Q: Digital CATV - DAP - Will the embedded guide information from the digital broadcaster be present in the ASI’s output of the DAP PLUS equipped with ASI module?
A:

Yes.

Q: Digital CATV - DAP - I have successfully scanned all the input channels from a cable feed – many of them QAM channels. When I use front-panel up/down keypad to try to select a channel, however, on the LCD screen sometimes I see the “Check Module” message, and sometimes simply illegible characters.
A:

DAP firmware has a bug that acts up when too many QAM channels are scanned. To avoid the problem described above, use the “UP” button (not the DOWN button) to reach the desired channel.

Q: Digital CATV - DQMx - To what extent can PSIP information be manipulated or created?
A:

Units manufactured since January 2011 have the ability to assign a virtual channel and short program name to each program stream (CVCT mode). Units prior to this date had firmware that could only offset the minor channels.

Q: Digital CATV - MDDM - Will the MDDM pass all programs from the off-air channel?
A:

No, the MDDM will pass only ONE program from the selected RF channel, not the entire channel.

Q: Digital CATV - MDDM - Is the unit’s software field upgradable?
A:

Yes, this unit is field upgradeable, through the Mini-USB port.

Q: Digital CATV - MDDM-860 - How do I get my MDDM-860 to output both audio and video when feeding it from a Drake DSE24 with a HDMI 1080i input as I only get audio? I’ve substituted other digital demodulators and TV’s which work fine.
A:

Check that the video profile is set to MP@HL on the Drake DSE24. Some tuners will not lock in if the profile is not correct. Profile settings for the DSE24 should be MP@ML for 480 @30fps and MP@HL for 720 @ 60fps or 1080 @ 30fps.

Q: Digital CATV - MUX-12A-IP - Will the MUX-12A-IP pass program guide information as related to off-air programs?
A:

No, the latest available software version (1.0.17) does not pass program guide information. Please check the Latest Software section of Blonder Tongue’s website for the latest released firmware and features.

Q: Digital CATV - MUX-12A-IP - When using commercial satellite receivers as input source to the MUX-12A-IP, why do I observe intermittent tiling and macro-blocking when the output is viewed on a QAM 256 channel (using an external QAM modulator or an EdgeQAM device)?
A:

Update the firmware to version 1.0.17 or later (available since 07/30/2013). Also verify if the ASI input stream/s are not peaking as it can cause the output stream to go above 38.8 Mbps limit for QAM 256. It has been noticed during lab tests that some of the ASI streams can intermittently peak up to 4 Mbps for a brief period of time above the Actual bitrate as displayed on the “Main > Status” screen.

Q: Digital CATV - MUX-12A-IP - I connect the MUX-12A-IP to my network, but get no output.
A:

The MUX-12A-IP must be connected from its GigE port to a GigE port on a switch for data transfer. It will not pass data if it is only hooked to the 10/100 BaseT port. The 10/100 port on the MUX-12A-IP is for local control only.

Q: Digital CATV - MUX-12A-IP - Will the MUX-12A-IP handle EAS (Emergency Alert System) signals?
A:

Yes, the 12th ASI input can be configured to handle the EAS input signal. This must be set up in the web interface.

Q: Digital CATV - MUX-12A-IP - What is the maximum bandwidth the MUX-12A-IP can handle?
A:

The maximum data throughput of the GigE port is 214 Mbps. However, if the IP output is going to a QAM modulator device, the limitation would be the QAM modulator, which is 38.8 Mbps for QAM 256.

Q: Digital CATV - MUX-2D-QAM - I am receiving two off-air channels, and every once in a while it seems that the channel numbers change. Why does this happen?
A:

If receiving two off-air channels, sometimes the PID information is the same. If the unit loses lock on the first channel, it may substitute the second channel for the first, since the PIDs are the same. It is recommended to increment the second channel’s PIDs (by 100) to prevent this from happening.

Q: Digital CATV - MUX-2D-QAM - With the MUX-2D-QAM, the QAM output constantly freezes and disappears. When it comes back, sometimes channel X is there, and sometimes it is not.
A:

If the incoming signal or SNR is weak, the MUX-2D will constantly recalculate the MUX output when it loses or gains that channel. During the MUX recalculation process, the output will not be present (5-15 seconds). Ensure the SNR is well above the threshold (18 dB for 8VSB, 23 dB for QAM 64, 30 dB for QAM 256), and that the incoming level is above the threshold (-20 dBmV for 8VSB and QAM 64, -15 dBmV for QAM 256)

Q: Digital CATV - QTM-HD / QTM-HD-NPU - QTM-HD/QTM-HD-NPU CANNOT lock to transponders of ECHOSTAR 8 @ 77º W. For firmware versions 3.4 and 3.5 (most likely shipped after 4/2006).
A:

Units will lock to these transponders in manual mode only. To configure the unit for “Manual” mode:
1. Power cycle the units.
    i. The QTMPCM will read current settings from each QTM modules. Configure the parameters as outlined below in any sequence. If the current setting of a parameter is the same as below, then skip and go to the next parameter.
2. Set desired transponder frequency (see page 19 of instruction manual)
3. Set mode to “MANUAL” (see page 21 of instruction manual).
4. Set decoder to “ADVANCED”.
5. Set Input baud rate to 22.500
6. Set Output modulation to “QAM256”
7. Set Alpha to 15%.
8. Set interleaver to I12, J17.
9. Set Output baud rate to 4.836. If QTM module is not locking, check feed and repeat from step 1 above.

NOTE:
Version 3.4 cannot be upgraded to V 3.7 due to hardware differences.
Version 3.5 is upgradeable to V 3.7 if desired, but upgrade is not necessary for manual mode operation.

Q: Digital CATV - QTM-HD / QTM-HD-NPU - QTM / QTM-HD CANNOT lock to transponders of ECHOSTAR 8 @ 77º W. For firmware versions 3.6 (most likely shipped after 8/2007).
A:

Firmware must be upgraded to version 3.7 in order to lock to these transponders. After upgrading to V 3.7, QTM will lock in “Manual” as well as “Auto” modes.

Q: Edge/IP - EQAM 420A-2-32 - Some TV sets on my system cannot lock to the QAM output of the EQAM unit?
A:

Most likely the TV set you are using only tunes to inverted QAM channels and the current DDQ version (1.7 or lower) on your EQAM does not support this. Verify the DDQ version on the “Network” screen and contact Blonder Tongue’s Technical Solutions Group to update the DDQ version to 5.6 or later.

Q: Edge/IP - EQAM-420 - Why can’t I communicate with the unit when I connect an EQAM-420A’s GigE and Control data ports to the same switch?
A:

The GigE and Control ports of the EQAM-420A must be connected to different unmanaged switches or subnets. If connected to a managed switch, ensure the two ports belong to different VLAN’s or subnets.

Q: Edge/IP - EQAM-420 - I downloaded the config file in .txt format and re-formatted. I then uploaded the file and subsequently received the following error: ERROR: Config File validation NOT successful! Please correct the issue and try again.
A:

Follow the steps below:
i. Open the .txt file in Notepad
ii. Take a print of the .txt file to check if there is any extra space between the two lines
iii. Ensure there are no hidden spaces between the lines using “Backspace” key
iii. Ensure there are no hidden spaces at the end of the line using the “End” key
iv. Save the changes and upload the config file using the “Config” tab

Q: Edge/IP - EQAM-420 - Will the EQAM pass GUIDE information or PROGRAM information that can be displayed on the television screen?
A:

No, it will not.

Q: Edge/IP - EQAM-420 - Will the EQAM-420A support more than 6 programs per stream?
A:

The EQAM-420A has the capability for Pro:Idiom™ on the output. Because of this feature, the unit is limited to 6 programs per stream maximum.

Q: Edge/IP - EQAM-420 - My output QAM channel is tiling and freezing. What should I do?
A:

Check what mode the unit is operating in, MPTS or SPTS?
1: If operating in SPTS verify the input streams selected are good and that the total bitrate does not exceed 38.8 Mbps at all times.
2: If operating in MPTS mode verify the input is clean and under 38.8 Mbps at all times.

NOTE:
Input streams can be verified by using a VLC player, TS reader or other test equipment capable of looking at IP streaming video.

Q: Edge/IP - IPAT - What IP format does the unit accept?
A:

The IPAT will accept RTP or UDP streams. Ensure that the correct stream type is selected in the unit, or it will not see the stream.

Q: Edge/IP - IPAT - What bandwidth will the unit handle?
A:

The IPAT can handle 270 Mbps on the ASI port, but if you are going to a QAM modulator you cannot exceed 38.8 Mbps for QAM 256.

Q: Edge/IP - IPME - Occasionally my units receiving the stream will go blank. When I reboot the IPME it recovers and then may run for a week or so before it happens again.
A:

Enabling the SYSTEM INTEGRITY in the IPME will allow it to auto-recover if there are incoming video glitches. This setting can be done in either the HyperTerminal interface or the web interface.

Q: Edge/IP - IPME - I have a new unit and cannot access it via web interface.
A:

By default, the web interface is disabled. You must go into the unit via HyperTerminal and enable the web interface, as well as assign an IP address for the unit.

Q: CATV - BIDA Series - Is the 5800/5900 series amplifier set up for return path capabilities out of the box?
A:

The 5800/5900 series BIDA is set for PASSIVE return capability out of the box. To activate the return amplifier you must open the unit and move jumpers around to enable the return amplifier stage.

Q: CATV - FIBT / FIBR - Can I use FC/UPC connectors in my system?
A:

No, it is strongly recommended to use APC (angle polished connectors) throughout the system. Anywhere there is a flat connection in the fiber plant, reflections can occur, causing problems with the signal. Worst-case scenario is where the flat connector is near the transmitter, and it could reflect enough signal back into the transmitter as to cause damage.

Q: CATV - FIBT / FIBR - Do I have to maintain my channels below channel 110?
A:

These units are rated to 860 MHz, so you could run up to channel 135. If these units see more than 110 channels, you will need to lower the total input level into the unit, so the composite power does not exceed operating input.

Q: CATV - Will the CEF (Channel Elimination Filter) work to eliminate a digital channel?
A:

NO. The CEF was designed for analog channels, and we do not make it for digital currently.
