6.3 Controlling via RS-485
You can control a
VP-4x8
unit via an RS-485 controller, for example, a PC
(equipped with an RS-485 interface) or a Master Programmable Remote
Control system such as the Kramer
RC-3000
1
.
To connect an
RC-3000
to a
VP-4x8
unit (see
Figure 5
):
1. Connect the RS-485 terminal block port on the
RC-3000
to the RS-485 port
on the
VP-4x8
unit, as follows:
Connect the “ A” (+) PIN on the RS-485 rear panel
port of the RC-3000 to the “ A” (+) PIN on the
RS-485 rear panel port of the VP-4x8 unit
Connect the “ B” (-) PIN on the RS-485 rear panel
port of the RC-3000 to the “ B” (-) PIN on the
RS-485 rear panel port of the VP-4x8 unit
If shielded twisted pair cable is used, the shield may
be connected to the “ G” (Ground) PIN on one of the
units (for example, on the RC-3000)
2. Set the
VP-4x8
unit as Machine # 1, according to
Table 6
(that is, DIP 1,
DIP 2, DIP 3, and DIP 4 OFF), and set the other dipswitches on the
VP-4x8
unit, as follows:
Set DIP 5, DIP 6, and DIP 7 OFF
Set DIP 8 ON (for RS-485 Line Termination with
120 )
