7 Connecting the VP-747 Control Ports

This section describes how to connect the VP-747control ports, that is, the:

•RS-232 port, see Section 7.1

•TO AUDIO UNIT port, see Section 7.2

•TO CONTROLLER port, see Section 7.3

•ETHERNET port, see Section 7.4

7.1Connecting a PC (via RS-232)

You can connect a PC (or other controller) to the VP-747via the RS-232 port for remote control.

To connect a PC to a VP-747unit, using the Null-modem adapter provided with the machine (recommended):

•Connect the RS-232 9-pin D-sub rear panel port on the VP-747unit 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-747unit, 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-747unit, forming a cross-connection1, as Figure 6 illustrates
