Troubleshooting

Problem: Test Communications Interface operation fails.

Solution: Check that:

• Each display is correctly congured to use either then LAN or RS232 interface by conrming the EXTERNAL

CONTROL setting on the OSD menu (for models that support RS232 daisy-chaining). Newer models that support

LAN daisy-chaining don’t have this setting.

• The MONITOR ID is set correctly on the OSD and matches the value assigned in the software.

If using RS232:

• If using daisy-chaining, conrm that no other displays on the same chain have the same MONITOR ID.

• Make sure that each display is connected via a NULL modem cable and that the correct IN our OUT socket on

the display is used.

• Make sure that no other application or process is using the specied COM port.

If using LAN:

• Make sure that the IP address of each display is set correctly and that each display has a unique IP address.

• Make sure that the IP address assigned to each display matches those assigned in the software.

• Make sure that no other device on the LAN is assigned the same IP address.

• The IP address of each display must be congured using a web browser. The default IP address is 192.168.0.10.

• Make sure that the displays are on the same subnet as the host PC being used.

• Make sure that there are no rewall settings or antivirus applications that may be preventing the application from

accessing the LAN. Displays communicate using Port 7142.

• Try resetting the LAN settings from the OSD.

• If using LAN daisy-chaining, make sure that LAN 2 (output) connects to the LAN 1 (input) on the next display in

the daisy-chain. The start of the daisy-chain should be to LAN 1 (input).

• Try resetting the monitor power.
