After Market Kit Installation Overview
Identify components included in the kit.
(1) Communication gateway
(2) Cellular antennae
(1) GPS antenna
(1) Wifi antenna (not required for typical installation)
(1) Easy connect harness
(1) Ethernet network cable
(1) 120VAC power supply (not required for typical installation)
(1) RS232 comm port breakout board and cover
(1) Din railIdentify existing din rail for mounting of gateway or find suitable location to mount included piece. Gateway should be mounted in interior of gen controller enclosure where possible to limit vibration and weather exposure.
Connect included cell antennae to AUX and ANT ports on top of the gateway. Mount as close to outside of gen enclosure as possible. Antennae ends should be separated approximately 12”-18”. Installation of a drip loop is required to keep water from entering unit.
Connect included GPS antenna to GPS port on top of gateway. Mount as close to outside of gen enclosure as possible. Installation of a drip loop is required to keep water from entering unit.
Inspect wiring harness and identify customer and gateway ends. Gateway end will have 3 pre-wired green terminal blocks.
Route customer end to be near generator termination points. See generator controller specific reference pages for recommended terminations.
Make final connections on customer end per documentation.
Connect 7 pin terminal block (TB1) with Red, Black, Orange/White, White/Orange, and Blue/White wires to terminal block receptacle on top of communication gateway.
Confirm data cable connections are correct on gateway side for either RS485 (A/B) or RS232 (TXD/RXD) applications.
Connect 8 pin terminal block (TB2) with Yellow, White, Green, Purple, and Orange wires to front side, top terminal block receptacle.
Connect 8 pin terminal block (TB3) with Brown, Black, and Blue wires to front side, bottom terminal block receptacle.
If included ethernet cable is being used for communications, connect to the bottom port on front of gateway labeled ‘GE0/2’.

*If gateway power lights blink on gen crank this can indicate a brief loss of power to gateway. To correct, please make power connections directly to battery posts.
**Gateway can support either positive or negative inputs for ‘On’ condition. If Orange wire is terminated to DC- then gateway will sense an ‘On’ condition when input wires (Purple/Green/White/Yellow) have DC+ signal applied. If Orange wire is terminated to DC+ then gateway will sense an ‘On’ condition when input wires have DC- signal applied.
Troubleshooting
Check gateway side data cable connections on TB1 (OR/WH, WH/OR, BLU/WH).
For RS232 applications (for example, G or H Panel):
TXD—Orange / White
RXD—White / Orange
GND—Blue / WhiteFor RS485 applications (for example, DSE 7300 or Generac PZ Pro):
A—Orange / White
B—White / Orange
GND—Blue / WhiteCheck customer / device side connections.
For RS232 applications use provided breakout board:
2 RXD (Receive)—Orange / White
3 TXD (Transmit)—White / Orange
5 GND (Ground)—Blue / WhiteFor RS485 applications:
Modbus POS—Orange / White
Modbus NEG—White / Orange
Modbus REF—Blue / WhiteConfirm ethernet connected devices are programmed with the correct IP address.
