Controlling the VA-8xl
You can control a single
VA-8xl
unit (see
Section 6.1
) or configure up to a 120
channel balanced stereo audio amplifier, using 15 units via RS-485 or RS-232
(see
Section 6.3
).
6.1
Controlling a Single VA-8xl Unit
To connect and control a single
VA-8xl
unit, connect the following to the rear
panel:
•
PC or other controller, see
Section 6.2
: “Preparing the RS-232
Port on a Single Unit”
•
Set the DIP-switches, see
Section 6.2.1
•
Power cord
6.2
Preparing the RS-232 Port on a Single Unit
You can connect to the unit via a crossed RS-232 connection, using for example,
a PC. A crossed cable or null-modem is required as shown in method A and B
respectively. If a shielded cable is used, connect the shield to pin 5.
Method A
(
Figure 7
)—Connect the RS-232 9-pin D-sub port on the unit via a
crossed cable (only pin
2
to pin
3
, pin

need be
connected) to the RS-232 9-pin D-sub port on the PC.
Note:
There is no need to connect any other pins.
Figure 7: Crossed Cable RS-232 Connection
Hardware flow control is not required for this unit. In the rare case where a
controller requires hardware flow control, short pin 1 to 7 and 8, and pin 4 to 6 on
the controller side.
