Product Overview
GPS Technology Support
The IR1800 obtains GPS service through either the installed PIM modules, or from the dedicated
IRM-GNSS-ADR module. Cisco supports GPS only with the initial IOS XE release 17.7.1. Please inquire
with your sales representative for a roadmap of support for additional constellations.
Power Supply
IR1800 comes with an external DC power connector. The 4-pin power entry connector (receptacle) is mounted
to the unit. The 4-pin power-entry mating connector (plug) is attached to the receptacle. It is removed during
installation and used to connect to the DC power source, and then reattached to provide power to the unit.

Serial Ports
IR1800 supports up to two RJ-45 RS232 ports (depending on the model) that conform to EIA-561 standard.
The pinout is shown in the table below.
One RS232 RJ45 serial port (S0) is intended as a DTE port supporting legacy RS232 equipment. The second
serial port (S1) is intended as a DCE port, capable of both RS232 and RS485. RS485 can support full or half
duplex.
The RJ45 pinouts are shown in the following figure and table:
