output level and EQ., master audio output level and microphone level

 Recalls previous setup via the non-volatile memory

 Is controllable via the front panel buttons or by RS-232 serial commands

transmitted by a touch screen system, PC, or other serial controller

 Includes an additional audio switching section that routes one of the

pre-selected audio inputs from the other switching sections to a separate

output

 Supports changing the master audio output levels via RS-232 commands

To connect the VP-23xl, connect as follows

to the rear panel

1. The required Composite, s-Video and VGA/XGA video sources and

acceptors as well as the appropriate balanced audio sources and acceptors.

2. A dynamic

microphone or a condenser

, if required.

3. The power cord.

software or other controller).

2. An audio amplifier to the Master Audio Out connector

1 Switch OFF the power on each device before connecting it to your VP-23xl. After connecting your VP-23xl, switch on its

power and then switch on the power on each device. Switching on the VP-23xl, recalls the previous setup from the non-

volatile memory

2 You do not need to connect all inputs

3 Use the Con / Dyn switch (refer to the rear panel, item 2 in Figure 1) to select a dynamic microphone or a condenser

4.1.1 Connecting a PC

You can connect a PC (or other controller) to the VP-23xl via the RS-232

port.

To connect using the Null-modem adapter provided with the machine

(recommended method):

 Connect the RS-232 DB9 rear panel port on the VP-23xl to the

Null-modem adapter and connect the Null-modem adapter with a 9 wire

flat cable to the RS-232 DB9 port on your PC

To connect without using a Null-modem adapter:

 Connect the RS-232 DB9 port on your PC to the RS-232 DB9 rear panel

port on the VP-23xl, as Figure 2 illustrates (depending on whether the PC

has a 9-pin or 25-pin connector)
