Troubleshooting 

Problem

Probable cause(s)

Remedy

LCS does not connect to any 
panels. LCS message bar reads 
“No RS232-DSP Interface 
found” at startup.

No power to DVI Buffer Box via DVI input 
cable.

Check the “DVI com.” LED. If it is not lit, check DVI 
input connections and verify that the media server 
is running. 

DVI Buffer Box not connected to a COM port 
from 1 to 4.

Check the RS-232 connections and verify that the 
device is connected to a COM port from 1 to 4. 
When connected properly, the “RS-232 com.” LED 
will flash in response to commands from LCS. Exit 
LCS and restart. 

Conflict with another device connected to 
COM port 1 to 4. 

Test system without other devices connected to 
COM ports 1 - 4. Assign the conflicting to device to 
COM port 5 or higher. 

Some panels respond to LCS, 
some do not.

The DVI splitter does not relay the 
DDCCLOCK and DDCDATA signals on pins 6 
and 7 to every output. 

Short term: reset panels and exit LCS.
Long term: replace DVI splitter. See LC Series user 
manual for recommendation. 

Outdated firmware

Update panel firmware.

Panels do not start up with the 
expected settings.

Failure to save settings in non-volatile 
EEPROM memory. 

Click Save Parameters after making changes to 
settings. 

Some panels set for a previous application.

Refresh wall, then apply factory default settings and 
save so all panels have same settings. Adjust 
settings as desired and save again.
