SS 4x4 Installation and Operation Manual
INSTALLATION
Serial Communication
The SS 4.4’s serial communication is supplied with a multi-drop RS-232 port, allow-
ing up to four SS 4.4’s on the same computers serial port. Commands may be
entered either via a menu (menu mode) or a short form code (ASCII serial string-
burst mode).
All commands and responses use normal ASCII characters, facilitating scripting. A
burst mode command starts with an asterisk (*) followed by the device (ID) address
as a single decimal digit, then the command. The command to enter menu mode is:
*0MM. The menu mode displays certain parameters, and allows for the control
and/or configuration of most switcher functions.
User Programming
The SS 4.4 programming is stored in non-volatile memory. Configuration is set with
selection dipswitches and computer commands.

during shipping. If any is noted, please notify the shipper immediately and retain
the packaging for inspection by the shipper.
The package contains the SS 4.4, universal input, multi-voltage DC switching power

Installation Guidelines
Setting “OPTION” Dipswitches
The SS 4.4 is equipped with an 8-position “OPTIONS” dipswitch. The dipswitch
specifies 2-bit unit ID, baud, audio modes (mix, interlock, overlap), and other features
listed below. Access to this switch is on the rear panel. Follow the description below.
CAUTION! The DIPswitches are read from RIGHT to LEFT (SW 8 on the left and
SW 1 on the right). You will also need to use small needle-nose pliers to turn the
switches ON. In later versions of the PCB assembly, this will be corrected.
