6.6 Controlling via the RS-485 Port
To cascade up to eight individual VS-44HD units, via RS-485 (with control
via a Master Programmable Remote Control system such as the Kramer
RC-3000), as Figure 6 illustrates, do the following:
1. Connect the “A” (+) and “B” (-) PINS on the RS-485 terminal block port
of the RC-3000 to the “A” (+) and “B” (-) PINS, respectively, on each of
the eight VS-44HD units. (If using shielded twisted pair cable, the shield
is usually connected to the “G” (Ground) PIN of the first unit).
2. Set the first VS-44HD unit as MACHINE # 1 and the following seven
VS-44HD units as MACHINE # 2 to MACHINE # 8, according to Table
3.
