Setting the Switching Delay Time
You can achieve clean transitions when switching between non-genlocked
sources by setting the delay time—ranging from 0sec to 3.5sec
1
To set the delay time, do the following:
. The factory
default delay is to 0sec.
1. Press the VIDEO and AUDIO front panel buttons simultaneously.
The 7-segment display shows the current switching delay time.
2. Use the + and – front panel buttons to set the delay time as required.
To exit the Delay mode, press the TAKE front panel button.

Setting the Machine Number
The MACH. # (machine number) determines the position of a
VP-4x8AK
unit when cascading units.
To set the MACH. #, do the following:
1. Press the STO and RCL front panel buttons simultaneously.
The 7-segment display shows the current machine number.
2. Use the + and – front panel buttons to set the machine number as required.
To exit the MACH. # mode, press the TAKE front panel button.

Cascading Machines
You can cascade up to 16
VP-4x8AK
units with control from a PC or serial
controller.
To cascade up to 16 individual
VP-4x8AK
units via RS-485 (as illustrated in
Figure 10
), do the following:
1. Connect the sources and acceptors, as
Section 6.1
describes.
2. Connect the RS-232 port

3. Connect the RS-485 terminal block port on the first unit to the RS-485 port on
the second
VP-4x8AK
unit and so on, connecting all the RS-485 ports.
of the first
VP-4x8AK
unit to a PC.
4. Set the machine numbers of the connected machines, as described in
Section
6.8
, by set the first
VP-4x8AK
unit as Machine # 1 and the following 15
VP-4x8AK
units as Machine # 2 to Machine # 16.
