Serial Communication (SCOM) Interface
Installation in display
Connectorization
The remote control has either two or one 9 pin D-subs for communication. For systems with more
than one unit, the units are connected together through the unoccupied D-sub. It is regardless
which one is used, but normally COM-1 is connected to another unit, and COM-2 is connected to
the PC. On units with just one connector it is connected to the PC equipment for single
communication only.
Address
A display's address is set by a 5-bit dipswitch (red) on the backside of the display (own page in this
manual describes its location). Only bits 1-4 are currently in use. The position of bit 5 has no effect.
Address is adjusted according to the following table:
