Projector status
The projector “status” LED (A) lights up green while in operation. The same LED lights up red when the projector is switched to
standby.
Besides the projector status LED (A) the communication interface has also a “warning” LED (B) which blinks in case the projector
encounters an internal problem concerning fan speed, temperature, supply voltages, ... etc. These type of problems still allows
the projector to operate (the show can go on) but an action will be required within a short time period. More information about the
involved problem is given on the local LCD display of the projector.
A two character 7-segment display (M) shows, during normal operation, the selected input slot number. If an error has occurred
then an error code appears on this two digit display.
IR communication (RC5)
An IR receiver (L) is mounted on the communication interface. Note that there is also an IR receiver mounted at the front and at the
back of the projector. When using the remote control unit (wired or wireless), the “IR REC” (D) and the “IR OK” (C) LED’s will light
up indicating an IR signal was received and recognized.
Wired remote control
If desired the remote control unit can be wired and plugged in into the male XLR port (K) on the communication interface.

RS232/422 serial communication
The communication interface of the CLM HD8 supports RS232 and RS422 serial communication. You can use the RS232/RS422
input port (J) to connect a local PC to your CLM projector. This way you can configure and control your CLM projector from your
local PC.
Do not forget to set the projector’s baud rate to match that of the computer.
The communication interface has also an active RS232/RS422 loop through output port. Whenever the projector has no power, a
passive loop through is created from the RS232/RS422 input port to the RS232/RS422 output port. So, the following projector in
the daisy chain will still receive his RS232/RS422 commands.
Advantages of using RS232/RS422 serial communication:
• easy adjustment of the projector via PC (or MAC).
• allow storage of multiple projector configurations and set ups.
• wide range of control possibilities.
• address range from 0 to 255.
• sending data to the projector (update).
• copying data from the projector (backup).
