8.2 Control
Configuration via RS-485
To control up to seven single
VP-88ETH units via an RS-485 controller, for
example, a Master Programmable Remote Control system, such as the Kramer
RC-3000
1
, or a PC (equipped with an RS-485 interface), as Figure 16
illustrates, do the following
2
:
1. Connect the video sources and acceptors, the appropriate audio sources and
acceptors, and the power cord to each
VP-88ETH unit.
2. On each
VP-88ETH unit, set the SELF ADDRESS # dipswitches, as
required. For example, set the first
VP-88ETH unit to SELF ADDRESS # 2,
the second
VP-88ETH unit to SELF ADDRESS # 3, and so on - up to SELF
ADDRESS # 8 for the seventh
VP-88ETH unit (see section 6.5.1).
3. Terminate the RS-485 line on both the
RC-3000
3
and on the last
VP-88ETH
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
VP-88ETH 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
VP-88ETH 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
VP-88ETH 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 Previously known as VS-3000
2 Switch OFF the power on each device before connecting it to your VP-88ETH. After connecting your VP-88ETH, switch
on its power and then switch on the power on each device
3 Refer to the RC-3000 user manual for details of how to terminate the RS-485 line
