Appendix A:
Troubleshooting
a. Can’t establish one-way Serial communication:
- Make sure Serial settings are: 9600 Baud, 8 bits, No Parity, 1 Stop Bit. No
Flow Control
- Double check to make sure flow control is turned off.
- If you connect the ARQ’s Rear Serial Port to a PC Serial Port, run a terminal
program at the above baud rate and type ‘3’,’c’,’3’,’g’ you will see feedback
on the terminal program. This is a good sanity check to verify a good cable.
- If you have an ARQ1 make sure it has a serial port. There were early models
that did not have a serial port. Call ReQuest Multimedia with the hardware
version if you are not sure. (You can find the hardware version in MENU-
>SYSTEM INFORMATION)
- Check to make sure the AudioReQuest is not encoding or doing any File
Transfers.
- If you are trying to establish communication with a ZONE though serial using
the included cables and you received your zone before December 15
th
then try
putting a NULL Modem adapter (the wrong cable was included during that
time frame on ZONE’S)
b. Have one-way control, now can’t get any text out of AudioReQuest onto
my Crestron touch panel:
- Make sure you are sending the “Data Request” command. AudioReQuest will
not send any data until it is requested. The most commonly used data
request (used in all demo Crestron Programs) is Delimited GUI. Send the
following hex numbers and you should see feedback: [0x33,0x63]
[0x33,0x67]. In the ARQ Crestron Macro this is the START-
COMMUNICATIONS line. Make sure that this is being sent in Test Manager.
- If you connect the ARQ’s Rear Serial Port to a PC Serial Port, run a terminal
program and type ‘3’,’c’,’3’,’g’ you will see feedback on the terminal program.
Now, if you connect it back to the control system and it works (shows text on
touch panel) it is because you did a ‘Data Request’ in the terminal program.
Power off/on the ARQ and Crestron control processor and if there is no
feedback the ‘Data Request’ command is not being sent.
- Check the firmware version in AudioReQuest. (You can find the software
version in MENU->SYSTEM INFORMATION) Much of the feedback sent
requires firmware version 1.6.0 or higher. (Software updates can be done
either by CDROM or online)
- Check www.request.com
under SUPPORT->DOWNLOADS to make sure you
have the latest version of the ARQ Crestron Demo Program and corresponding
touch panel files.
