2.2.4.1 Digital Input Contacts
The digital input channel is used to interface a potential free
contact, e.g., a relay. It could be a fire alarm sensor, door sensor,
or failure signal from a power supply in a base station site. The
DI can read the digital input channel status and determine its
alarm state. The INPUT and GND pins are used to make a digit­
al input connection.
Pin Label Description Specification
INPUT Digital Input Channel Logical level 0/1.
Max. Input DC +30V, 100mA
GND Ground of I/O Channels Ground

menu.
2.2.4.2 Digital Output Contacts
This module has two relay outputs. The relay outputs are dedic­
ated circuits that can be directly connected in­line with the
desired control or indicating device.

2.2.5 Ethernet Port
An Ethernet port labelled “LAN 10/100M” is provided on the
front of the controller.
This port is used to provide access to the
web‐based user interface either by connecting directly to a local
PC or to a router for remote access.
2.2.6 USB Port
A USB port labelled “USB 2.0” on the front of the controller
is reserved for future expansion.

2.2.7 Reset Button
A recessed reset button is provided on the front of the control­
ler to perform a hard power‐on reset. Press the button
momentarily to restart the AISG‐RM3 controller. Press and
hold the button for approximately 6 seconds to restore network
settings to the factory default.
2.2.8 Power Connector
A 3‐port pluggable power connector is provided on the front of
the controller to power the unit. The input voltage range for the
