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