No Response, No Twisted Pair Output | Altinex UT250-101 instruction

DESIGNER SOLUTIONS

8.3 NO RESPONSE

Cause 1: The unit is not recognized.

Solution: Reset the unit by turning the system power off and then on again. Send the [STATUS] command to see if there is communication with the unit. If there is no feedback, see Cause 2.

Cause 2: Unit is disconnected from RS-232.

Solution: Check the RS-232 connection to the unit. Make sure the terminal block connector is pushed all the way in and that all the wires are connected. If the unit is still not recognized, see Cause 3.

Cause 3: Communication settings are bad.

Solution 1: Verify the communication software settings. The UT250-101default settings are as follows:

Baud Rate ..	9600	Flow	None
Data Bits	8	Parity	None
Stop Bits	1

Solution 2: Verify the correct port is selected in

the communications software: COM1, COM2, etc. If there is still a problem, please call ALTINEX at

(714)990-2300.

8.4NO SOUND/SOUND TOO LOW Cause 1: The source has a problem.

Solution: Check the source and make sure that it is working at an appropriate volume level and all source connections are correct. If the source is working and there is still no sound, see Cause 2.

Cause 2: The wrong output is selected.

Solution: Check the status of the unit using the RS-232 commands in section 7. Verify the correct input-to-output connection is selected and enabled. If no sound is present, see Cause 3.

Cause 3: Cable connections are incorrect.

Solution: Make sure that cables are connected properly. Also, make sure that the continuity and wiring are good. If there is still no sound present, see Cause 4.

Cause 4: Destination amplifier has a problem.

Solution 1: Make sure that the destination amplifier is powered. If there is still no sound, see Solution 2

Solution 2: Set the volume of the destination amplifier to a reasonable level. If there is still no sound, see Solution 3.

Solution 3: If the video output is working and only the audio is missing, there may be a problem with the UT250-101, call ALTINEX at (714) 990-2300.

8.5 NO TWISTED PAIR OUTPUT

Cause 1: The output is not selected.

Solution: The TP output is the same as the VGA output. Verify the connection status of the UT250-101. (See RS-232 accessible commands in Section 7.) If no display is present at the TP receiver, see Cause 2.

Cause 2: No input signal applied.

Solution: Make sure that the selected input has a valid image applied. Connect a local monitor to the VGA output of the UT250-101that corresponds to the TP output. If an image is present, there may be a problem with the UT250-101. Call ALTINEX at (714) 990-2300.
