You can connect a PC (or other controller) to a standalone
VP-727A-BA
via
the RS-232 port for remote control and for upgrading the firmware.
To connect a PC to a
VP-727A-BA
unit, using the Null-modem adapter
provided with the machine (recommended):
•
Connect the RS-232 9-pin D-sub rear panel port on the
VP-727A-BA
unit
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 a PC to a
VP-727A-BA
unit, 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-727A-BA
