Connecting a PC
You can connect a PC (or other controller) to the
VP-26
via the RS-232 port.
To connect using the null-modem adapter provided with the machine
(recommended method):
•
Connect the RS-232 9-pin D-sub rear panel port on the
VP-26
to
the null-modem adapter and connect the null-modem adapter with a
9-wire flat cable to the RS-232 9-pin D-sub port on your PC
To connect without using a null-modem adapter:
•
Connect the RS-232 9-pin D-sub port on your PC to the RS-232
9-pin D-sub rear panel port on the
VP-26
, as
Figure 9

Connecting via RS-485
You can control a
VP-26
unit via an RS-485 controller, or a Master
Programmable Remote Control system such as the Kramer
RC-3000
.
To connect an
RC-3000
to a
VP-26
unit (see
Figure 10
), connect the
RS-485 terminal block port on the
RC-3000
to the RS-485 port on the
VP-26
unit, 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 port of the
VP-26
unit
•
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 port of the
VP-26
unit
•
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
)
