SS 16.4 Installation and Operation Manual
CONTROLS
Relay Outputs, 8 Port Output Control:
The SS 16.4 contains 8 spst (normally open) relays. Each relay may be latched on,
latched off or pulsed on by serial burst commands. The relay “pulse” time may be
set from zero to 9.9 seconds. The default pulse length is one second.
Serial Communication:
The SS 16.4’s serial communication may be configured for either multi-drop RS-
232 or RS485, allowing up to 8 - SS 16.4’s on the same computer’s serial port.
Burst mode allows a computer or ASCII terminal to control and interrogate the unit.
This section defines all burst mode commands. Each burst mode command starts
with an asterisk (“*”). Next is a single decimal digit that corresponds to the unit
(ID) address 0-3. Following that are one or more ASCII characters specifying the
command. No carriage-return or line-feed is required to terminate the command
except for those few commands of variable length, if the maximum length is not
sent. If acknowledgements are enabled, successful commands are responded to
with “RRR” while errors get an “EEE” response. The syntax of each command is
given below. The syntax shows the command exactly as it should be sent, except that
lower case characters represent values that should be substituted:
User Programming:
The SS 16.4 programming is stored in non-volatile memory. Configurations are set
with selection dipswitches and computer commands.
Inspection:
Please examine your SS 16.4 carefully for any damage that may have been sustained
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 16.4,
“Lump in the line” power transformer, Installation manual, reversed modular serial
cable and the 9-pin D-Sub (S 9) adapter.
Setting Operation “DIP” Switches:
The SS 16.4 is equipped with an 8-position “PGM” DIP Switch. The DIP Switch
specifies 2 bit unit ID, baud rate, audio modes (mix, interlock, overlap), power up
modes, remote control and other features listed below. The dipswitch (SW 24) is
located on the rear panel.
