6.3 Controlling via the RS-485 Port
To cascade up to eight individual
VS-41HD
units, via RS-485 (with control
via a Master Programmable Remote Control system such as the Kramer
RC-3000
), as
Figure 5
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-41HD
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-41HD
unit as MACHINE # 1 and the following seven
VS-41HD
units as MACHINE # 2 to MACHINE # 8, according to
Table 3
.
