6.7 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
. The factory
default delay is to 0sec.
To set the delay time, do the following:
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.
6.8 Setting the Machine Number
The MACH. # (machine number) determines the position of a VP-8x8AK
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.
6.9 Cascading Machines
You can cascade up to 16 VP-8x8AK units with control from a PC or serial
controller.
To cascade up to 16 individual VP-8x8AK 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
2
of the first VP-8x8AK unit to a PC.
3. Connect the RS-485 terminal block port on the first unit to the RS-485
port on the second VP-8x8AK unit and so on, connecting all the RS-485
ports.
4. Set the machine numbers of the connected machines, as described in
Section 6.8 , by set the first VP-8x8AK unit as Machine # 1 and the
following 15 VP-8x8AK units as Machine # 2 to Machine # 16.
