If a rack is not air conditioned, you need to space all active equipment with a minimum of one rack space. Even with a closed rack it's good to do, many engineers place draw fans in the top of the rack to pull the A/C upwards and vent the heat. The closer you can keep the equipment to 68/70 degrees the better.

NO. Only AQM firmware version 1.4 or higher is compatible.

NO.

AQT units with firmware version 5.1, 5.2, and 5.3 does not lock to some QAM channels and the AQT firmware must be updated to 5.5 version.

The AQT_PCM firmware version 3.1 will work just fine if the AQT is being used to transmodulate 8VSB to QAM; However, If AQT input signal is QAM then the AQT-PCM needs to get upgraded to latest version which is 3.3.

The AQT_PCM can be remotely updated using an AQT-RCS (with a network connection) or a using an AQT-PCM Upgrader. If the firmware version of the AQT-PCM is 3.3 then there is no need to update the firmware. This is a latest update as of July 2008.

The AQT software can be updated using handheld programmer. Or the Units can be sent back to factory for an update. Use a Handheld programmer supplied by Blonder Tongue, then you will be able to upgrade the AQT Stock#6275 at the headend without removing it from the rack assembly. Simply follow the instruction on the handheld programmer. The units can also be sent back to factory for the firmware update also.

Please note that the QAM mode selection for locking to QAM must be set to “PASSTHRU” mode. Do not set the QAM mode to “Normal”. 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.

No, but it is important to note that the 5.1 firmware will not lock to HI VHF channels. Also the latest firmware version 5.5 resolved the issue that the AQT did not lock to some QAM channels. If the AQT is used in the UHF frequency range only, then there is no need to update the firmware, however, it is important to note that the 5.1 firmware version will not lock to VHF channel 7 through 13 and also the AQT will not lock to some input QAM channel.

Make sure the Power/data cable is plugged in securely, if this connector is ¾ 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.

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 a AQD software upgrade is required to implement the information correctly. Regarding Closed Captioning: AQD supports both the SCTE20 (608) and 608-in-708 captions.

Make sure the Power/data cable is plugged in securely, if this connector is ¾ 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.

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.

Yes, if the DAP software is upgraded with the TV Guide feature.

YES.

The settings selected in the AFD menu (section 5.22 of manual) takes priority over the settings selected in the “Picture Shape” option (section 5.6 of manual). If you want the “Picture Shape” option to take priority, you must turn the AFD option off. In other words, you can change the setting on the “Picture Shape” parameter and receive the “input accepted” message, but it will not have any affect on picture aspect being displayed if the AFD option is turned on.

Referring to the Reference Manual, per step 3 of Section 4.2, you must download the appropriate *.hex file. Make sure to select and download the file for DAP – not the file for AQD. Re-install the correct file and the unit will become operational again.

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.
