DIP-switch 4 sets the RS-485 bus termination of the VP-81KSi. Only the first and last physical units on the RS-485 bus must be terminated, all others must be unterminated. Moving the DIP-switch up turns the termination off (default), moving the switch down turns the termination on.

6.6.2Connecting and Controlling Multiple VP-81KSi Devices

You can daisy-chain up to eight VP-81KSidevices with operation via RS-232 from a PC or serial controller.

To daisy-chain up to eight VP-81KSi devices:

1.Connect the RS-232 port1 on the first VP-81KSidevice to the PC (see Section 6.3).

2.Connect the RS-485 terminal block port on the first device to the RS-485 port on the second device, and so on for all devices.

3.Set the DIP-switches (see Section 6.6.1) as follows:

The first device is machine number 1 and the following seven devices are machine numbers 2 to 8

Terminate the first and last physical devices, that is, in this example terminate machine numbers 1 and 8. Ensure that all other devices are unterminated

6.7Cascading Multiple VP-81KSi Devices

You can cascade up to eight VP-81KSidevices to build a single “virtual” switcher with up to 57 inputs and one output as illustrated in Figure 9.

To cascade up to eight VP-81KSi devices:

1.Connect the output on the Master VP-81KSito the video acceptor (for example, a projector).

2.Connect Input 1 on the Master VP-81KSito the output of the second device.

3.Connect Input 1 on the second VP-81KSito the output of the third device, and so on for all devices.

1 Alternatively, the RS-485 port could be used for PC control
