4 Summary of how to Operate a Single Machine
By default, the VP-1608 is setup for use as a single machine. This means that
it is a 16x8 RGBHV / Balanced Audio Matrix (in audio-follow-video mode),
with all setups empty and each input connected to its corresponding output
(for example, input 1 to output 1). The dipswitches are set up for a typical
application using a single machine (see Figure 1):

6.4Setting the MACHINE # Dipswitches
The MACHINE # determines the position of a VP-1608 unit in the sequence,
specifying which VP-1608 unit is being controlled when several VP-1608 units
are controlled by a PC or serial controller. Set the MACHINE # on a VP-1608
unit via DIPS 1, 2, and 3 (DIP 4 is for RS-485 termination), according toTable 4.
When using a stand-alone VP-1608 unit, set the MACHINE # to 1 (see Figure 1).
When connecting more than one VP-1608unit, set the first machine (the Master)
connected via RS-232,as MACHINE # 1. The Master connects to the PC via the
RS-232 port. The other VP-1608 slave units (each set to aMACHINE # between
2 and 8) interconnect via their RS-485 ports to the RS-485 port onthe Master.

7.2 Control Configuration via RS-485
To control up to seven single VP-1608 units via an RS-485 controller, for
example, a Master Programmable Remote Control system, such as the
Kramer RC-3000
1
, or a PC (equipped with an RS-485 interface), as Figure 12
illustrates, do the following
2
:
1. Connect the video sources and acceptors, the appropriate audio sources
and acceptors, and the power cord to each VP-1608 unit.
2. On each VP-1608 unit, set the MACHINE # dipswitches, as required.
For example, set the first VP-1608 unit to MACHINE # 2, the second
VP-1608 unit to MACHINE # 3, and so on - up to MACHINE # 8 for
the seventh VP-1608 unit (see section 6.4).
3. Terminate the RS-485 line on both the RC-3000
3
and on the last
VP-1608 unit (set DIP 4 to ON).
4. Connect the RS-485 ports on the RC-3000 to the RS-485 ports on each
of the VP-1608 units, as follows:
 Connect the “A” (+) PIN on the RS-485 rear panel port of the
RC-3000 to the “A” (+) PIN on the RS-485 rear panel ports of the
VP-1608 units
 Connect the “B” (-) PIN on the RS-485 rear panel port of the
RC-3000 to the “B” (-) PIN on the RS-485 rear panel ports of the
VP-1608 units
 If shielded twisted pair cable is used, the shield may be connected to
the “G” (Ground) PIN on one of the units (for example, on the
RC-3000)
1 Previously known as VS-3000
2 Switch OFF the power on each device before connecting it to your VP-1608. After connecting your VP-1608, switch on its
power and then switch on the power on each device
3 Refer to the RC-3000 user manual for details of how to terminate the RS-485 line
