Overview
2.3.1 Connecting Interfaces
uses numbered labels to show the location of the interfaces for connections.
This manual uses these numbered labels at various places for your convenience.
The table below uses these numbered labels to describe the type and usage of the
interfaces.

1
Ethernet 1
J4
Primary Ethernet port (Eth1) that can permanently connect the
gateway board with the CLSS Gateway services or a Modbus
client/server.
The Ownership Code (OC) on it confirms the ownership of the
board. It should be registered in the
CLSS Site Manager
during
the first time installation of the CLSS Gateway.
Cable: CAT 5 standard Ethernet cable with RJ45 connector
2
Ethernet 2
J3
Secondary Ethernet port (Eth0) providing a TCP/IP connection
to a configuration computer.
Cable: CAT 5 standard Ethernet cable with RJ45 connector
3
RS-485B
P5 Receives the alarm data and device data from an RS-485 port
of a panel.
4
RS-485A
P1 Receives the alarm data and device data from an RS-485 port
of a panel.
5
UART/TTL
P4 Receives the alarm data and device data from a UART/TTL port
of a panel.
6
NUP
(RS-232)
P7 Transfers fire-related and device-related data from the panel to
the
CLSS Site Manager
through the gateway. It also helps in
administering the fire detection system.
Connects the gateway board to a panel’s RS-232 port.
If the connected panel supplies power, the gateway would get
power from the panel through the RS-232 port.
7
Power
P2 Connects to an external 24-volt DC power when required. It
uses a power-limited, regulated, power-supply-listed
connection for fire-protective signaling.
Twisted-unshielded pair, 12 to 18 AWG (3.31 mm² to 0.82 mm²)
It is used only when the gateway board is connected with:
• A network card
or
• When power is not supplied to the NUP connector
8
USB
J5
For future use.
9
Wireless
Aerial
E4 Wireless antenna
10
Cellular
4D 40-pin connector for the compatible cellular module.
