Controlling Several VS-88HCB Units
25
8.2 Control
Configuration via RS-485
To control up to seven single
VS-88HCB
units via an RS-485 controller, for
example, a Master Programmable Remote Control system, such as the Kramer
RC-3000
, or a PC (equipped with an RS-485 interface), as Figure 13
illustrates, do the following
1
:
1. Connect the video sources and acceptors, the appropriate audio sources and
acceptors, and the power cord to each
VS-88HCB
unit.
2. On each
VS-88HCB
unit, set the SELF ADDRESS # dipswitches, as required.
For example, set the first
VS-88HCB
unit to SELF ADDRESS # 2, the second
VS-88HCB
unit to SELF ADDRESS # 3, and so on - up to SELF ADDRESS
# 8 for the seventh
VS-88HCB
unit (see section 6.5.1).
3. Terminate the RS-485 line on both the
RC-3000
2
and on the last
VS-88HCB
unit (set DIP 4 to ON).
4. Connect the RS-485 ports on the
RC-3000
to the RS-485 ports on each of the
VS-88HCB
units, 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 ports of the
VS-88HCB
units
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 ports of the
VS-88HCB
units
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
)
1 Switch OFF the power on each device before connecting it to your VS-88HCB. After connecting your VS-88HCB, switch
on its power and then switch on the power on each device
2 Refer to the RC-3000 user manual for details of how to terminate the RS-485 line
