6.1 Connecting via a PC or Serial Controller
To connect up to eight single VP-1608 units from a PC or serial controller via
RS-232 and RS-485, as shown in
Figure 8, do the following:
Always switch off the power to each device before connecting it to your
VP-1608. After connecting your VP-1608, connect its power and then
switch on the power to each device.
1. Connect the video sources and acceptors, the appropriate audio sources
and acceptors, and the power cord to each VP-1608 unit.
2. On each VP-1608 unit, set the MACHINE # DIP-switches, as required (see
Section
5.3).
Set the first unit to MACHINE # 1 (Master), the second unit to MACHINE # 2, and so on
- up to MACHINE # 8 for the eighth unit.
3. Connect the RS-232 port on the first VP-1608 unit to the PC (see Section
5.1).
4. Interconnect the RS-485 ports on all the VP-1608 units: from the
RS-485 port on the first VP-1608 unit, to the RS-485 port on the second
VP-1608 unit, and so on – up to the RS-485 port on the eighth VP-1608 unit.
