Controlling the VP-88K

1. Connect the video sources and acceptors, the appropriate audio sources and

acceptors, and the power cord to each VP-88K.

2. Connect the RS-232 port on the first VP-88K to the PC (see

Section 6.2

3. Set the Machine # to 1 of the unit connected to the PC.

4. Set Machine 1 RS-485 termination to On (see

Section 6.5

5. Set the Machine # on all VP-88K units other than Machine 1 to a unique

number between 2 and 16 (see

Section 6.5

6. Set the termination on all VP-88K units other than Machine 1 to Off.

7. Interconnect the RS-485 bus on all VP-88K units:

 From the RS-485 connector on the first VP-88K unit, to the RS-485 port

on the second VP-88K unit, and so on. Up to sixteen VP-88K units can

be connected.

8.2 Controlling the VP-88K via RS-485

To control up to fifteen VP-88K units via an RS-485 controller or a PC

equipped with an RS-485 interface

Figure 22: DIP-switch Setting for Machine 2

1. Connect up to 15 VP-88K devices to the controller via RS-485 (see

Section 6.3

2. Connect the video sources and acceptors, the appropriate audio sources and

acceptors, and the power cord to each VP-88K unit.

3. Set the Machine number on the first VP-88K to be Machine 2 (see

Section 6.5

4. Terminate the RS-485 line on both the Controller/PC and on the last VP-88K

(set DIP-switch 1 to ON).
