GATEWAYELECTRONICSMODULE
The Gateway Electronics Module (GM20) is a small plastic enclosure which is DIN rail mounted
inside the outer metal enclosure of the gateway. The GM20 contains an electronics board with 5V
DC supplied through the gateway cable. The GM20 has screw terminals for the gateway cable (2
cores for 5V DC, 1 core for LED diagnostics, 3 cores for RS232 serial data) and a socket to connect
to the supplied gateway antenna with the supplied cable.

INSTALLATION INSTRUCTIONS
Identify gateway location
The Gateway should be mounted:
On a building with 5V DC availability and an Ethernet LAN connection.
Within 50m line-of-sight of the nearest Permasense WT100 sensor locations.
Away from a metal clad wall/roof.
The antenna should be on the top of the enclosure and be vertical.
The whole of the antenna should protrude above the top of a wall (if wall mounted).
At least 2.5m (8’) above solid obstacles in the space between the gateway and the
nearest sensor.
At least 1.5m (4.5’) from other wireless antennas or other Permasense Gateways to avoid
any possible ‘blinding’ effects.
Generally, the gateway should be mounted as high as possible to give the best wireless
range.
The gateways are supplied with a steel mounting plate but ideally the gateway can be mounted
on top of the sealed conduit carrying the cable.
Setting up the gateway enclosure outside
1. Feed the supplied 25m (80ft) 6-core screened cable through the mounted conduit into the
explosion-proof gateway enclosure.
2. Connect the cable to the GM20 gateway electronics module inside enclosure: The end of
the cable is labeled, as are the screw terminals on the GM20.
3. The shield of the cable should be connected to GND terminal of the GM20.
4. Check that the earthing cable inside the enclosure is connected from the earth screw
inside the enclosure to GND connection on the GM20.
5. Check that the antenna is connected between the gateway electronics module inside the
enclosure, using the supplied cable (BNC to SMA).
6. Use a ¾” NPT certified sealed conduit (NOT supplied) to seal the cable into the enclosure.
7. Mount the gateway electronics module onto the DIN rail inside the enclosure.

CB14 connection box wiring instructions
The CB14 connection box should be located inside the control room or building on which your
Permasense gateway is mounted. Permasense recommend mounting the CB14 within an
enclosure or cabinet - if possible - for added protection.
The CB14 features; Integral DIN rail mounting clips
Screw terminal connections
Replaceable 500mA fuse (installed from manufacture)
Diagnostic LEDs for power, data Tx/Rx, and gateway activity
The supplied 6-core screened cable has the wiring schedule attached at each end. Cores should
be attached like-for-like to terminals on the CB14 and the Gateway Electronics module inside the
gateway enclosure. The connections for the CB14 connection box are shown in the diagram
below.
The DB9 connection socket on the front of the CB14 is for connection to the Digi Port Server (not
supplied), and uses a female DB9-to-RJ45 crossover cable (supplied with Digi Port Server).
CB14 Connections
Connection notes:
-Terminate terminal X to ground for GT1xx gateways ONLY.
-DO NOT terminate terminal X for GT2xx gateways. The GT2xx series of gateway are earthed
at the enclosure outside
-All cables should be strain relieved in order to avoid maintain integrity of connections.
