1. Introduction
The STG/OUT16-S2 remote modules are field mounted and connected via RS485 buses to
the control panel Mu+S2. They provide 16 Open Collector outputs (negative switch)
with programmable functions to remotely trigger Sirens, Solenoid valves, Relays, etc.
Each STG/OUT16-S module can be connected to up to 2 boards and 8 relays (optional) that
convert the Open Collector output to a powerless exchange contact.
Each module must be addressed using the rotary switches placed on the PCB. The address
must be univocal and between 1 and 255.
Please refer to the control panel manual for the appropriate module using and setting.

3. Addressing
The STG/OUT16-S2 modules are addressed using the two rotary switches in RSW 1 and 2
hexadecimals. Rotary switches permit hexadecimal settings (base 16). Each switch as 16
positions (0-F) and the pointer is positioned on the number chosen using a screwdriver to
create a decimal value between 1 and 255 (see table). For the maximum number of modules
that can be connected to the unit refer to the control panel manual.
