5. Connections
Wired remote control
If desired the remote control unit can be wired and plugged in into the 3,5 mm mini jack socket (L) or, when using a rugged wire
with XLR plugs, plugged in into the male XLR port (M) on the communication interface. Besides the XLR input port a female XLR
connector (N) for wired RC5 output is provided. This connector creates a buffered RC5 signal, available for the next projector in
the daisy chain. Whenever the projector has no power, a passive loop through is created from the remote control input port to the
female XLR output port (N). So, the following projector in the daisy chain will still receive his RC5 code. Note that the RC5 in/out
signals are without carrier.

RS232/422 serial communication
The communication interface of the FLM HD20 supports RS232 and RS422 serial communication. You can use the RS232/RS422
input port (O) to connect a local PC to your FLM projector. This way you can con
fi gure and control your FLM projector from your
local PC.
Do not forget to set the projector’s baud rate (default = 115200) to match that of the computer.
The communication interface has also an active RS232/RS422 loop through output port (E). Whenever the projector has no power, a
passive loop through is created from the RS232/RS422 input port (O) to the RS232/RS422 output port (E). 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 con fi gurations 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).
