KRAMER: SIMPLE CREATIVE TECHNOLOGY
Connecting the VP-31KSi 3x1 UXGA/Audio STEP-IN Switcher
14
To daisy-chain up to eight VP-31KSi devices:
1. Connect the RS-232 port 1
5.5
on the first VP-31KSi device to the PC (see
Section ).
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 5.6.1 ) 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
 Terminate the first and last physical devices, that is, terminate machine
numbers 1 and 8. Ensure that all other devices are unterminated
5.7 Cascading Multiple VP-31KSi Devices
You can cascade up to eight VP-31KSi devices to build a single “virtual” switcher
with up to 57 inputs and one output as illustrated in Figure 10 .
To cascade up to eight VP-31KSi devices:
1. Connect the output on the Master VP-31KSi to the video acceptor (for
example, a projector).
2. Connect Input 1 on the Master VP-31KSi to the output of the second device.
3. Connect Input 1 on the second VP-31KSi to the output of the third device,
and so on for all devices.
Note: Audio connections must follow the same connection scheme as the video
connections.
4. Set the DIP-switches (see
Section 5.6.1 ) as follows:
 The first device is machine number 1 (Master) and the following seven
devices are machine numbers 2 to 8
 Terminate the first and last physical devices, that is, terminate machine
numbers 1 and 8. Ensure that all other devices are unterminated
