8 Controlling Several VS-88HCB Units
You can connect up to eight single VS-88HCB units with control from a PC
or serial controller via RS-232 and RS-485, or up to seven single units via
RS-485.
8.1 Control Configuration via RS-232 and RS-485
To control up to eight VS-88HCB units – with control from a PC or serial
controller – via RS-232 and RS-485, as Figure 12 illustrates, do the following:
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, set the SELF ADDRESS # as required 1
3. Connect the RS-232 port on the first VS-88HCB unit to the PC using the
Null-modem adapter provided with the machine (see section 6.2).
4. Interconnect the RS-485 ports on all the VS-88HCB units: from the
RS-485 port on the first VS-88HCB unit, to the RS-485 port on the second
VS-88HCB unit, and so on – up to the RS-485 port on the eighth VS-88HCB
unit.
1 Set the first unit to SELF ADDRESS # 1 (Master), the second unit to SELF ADDRESS # 2, and so on - up to SELF
ADDRESS # 8 for the eighth unit
