SS 4.1 Plus Installation and Operation Manual
INSTALLATION
Status
The status signals are supplied through the “Remote” control connector TB-3 as
individual open collectors. The open collectors may be used to provide status to a
remote control point to indicate which source is selected. The status open collector
(OCx) output for the selected channel will go low providing a return for an LED
indicator, TTL/CMOS logic or relay. External pull-up resistors may be required in
some installations.
Connecting the remote control, PIP / Trigger Inputs and OC’s / SS Relay
Most front panel functions of the SS 4.1 Plus may be remote controlled via the plug-
gable euroblock screw terminals located on the rear panel. The SS 4.1 Plus accepts
momentary contact closures (sustained, if break before make); open collector or
TTL/CMOS input logic levels. Connections to the remote control and/or PIP (trig-
ger) inputs are made on the TB-4. The following information is a comparison chart
to be used when connecting external devices.
