ACS 8.2 Plus Eight Input, Dual Output StereoMatrix Audio Control Switcher
INSTALLATION
INSTALLATION GUIDELINES
Serial Interface:
The ACS 8.2 Plus is supplied with a reversed 4 conductor modular cable and a (S9)
9-pin D-connector modular adapter for serial control. Only use the reversed mod-
ular cord that is supplied with the ACS 8.2 Plus or a replacement that reverses, such
as Radio Shack Cat No. 2790347. Connect the cable between the ACS 8.2 Plus and
your computer. The ACS 8.2 Plus may operate at baud rates from 2400 to 38400
baud. The unit is shipped set for 9600 baud, with 8 data bits, no parity and one stop
bit. Load Windows HyperTerminal using the protocol of 9600-N-8-1. Set the mode
to: DIRECT, Flow Control to: NONE and emulation to: ANSI.
Connecting Two ACS 8.2’s to a Single Computer’s Serial Port:
Multiple ACS 8.2 Plus’s may be cascaded serially to operate from the same serial
port. The first step is to assign ID’s to each ACS 8.2 Plus. One suggestion is to
assign 1 to the first ACS 8.2 Plus and 2 to the second switcher. The second step is to
parallel the serial ports of the ACS 8.2 Plus’s. Plug the male end of the duplex mod-
ular adapter into the supplied female (S9) DB-9 to RJ-11 adapter, then attach the
supplied reversed modular line cords into each of the duplex modular adapter recep-
tacles (Radio Shack Cat No. 279-0357) and the other ends into each ACS 8.2 Plus
modular receptacles. See the diagram below.
NOTE: Three or more ACS 8.2 Plus’s may be daisy chained by using the above
description and a Radio Shack Cat No. 279-0410, 5-jack modular adapter.
Serial Control:
The unit is controlled in either Menu or Burst mode. The ACS 8.2 can operate at the
following data rates:
2400; 9600 Default; 19,200; 38,400
Serial communications is multi-drop RS-232. Commands may be entered either via
a menu (menu mode for unit ID 0 only) or a short form code (burst mode). All com-
mands and responses use normal ASCII characters, facilitating scripting.
The pin out of the adapter is shown below.
