The unit accepts TIA-232-F (RS-232) level inputs andtransmits voltage levels that swing from zero V (ground) to 5 VTIA-232-F (RS-232) polarity.The GPS 18 PC can cause an issue with Windows operating systemsif the DB9 connector is plugged into the computer before thenavigation software is up and running. The Windows operatingsystem may interpret the serial connector on the GPS 18 as a serialmouse. Please refer to Appendix D: GPS 18 PC/ LVC/18-5Hz &Windows Serial Mouse Issue for complete details.1.4.3 GPS 18 LVC, GPS 18 LVC-5m, and GPS 18-5HzThese products interface to a serial port. The units accept TIA-232-F (RS-232) level inputs and transmitvoltage levels that swing from ground to the positive supply voltage, TIA-232-F (RS-232) polarity. Theyalso have reverse polarity protection. The cable contains wires for power, ground, receive, transmit, andmeasurement pulse output.At the end of the cable, the wires are terminated in a connector that isused by Garmin for testing purposes. Most customers will remove thisconnector and replace it with another connector of their own choosing.Removing the factory installed connector and/or replacing with anothercustomer-supplied connector will have no affect on the warranty (seeSection 1.2 Limited Warranty). The factory-installed connector will matewith JST right-angle PCB-mount connector (model BM06B-SRSS-TBT)or side-entry PCB-mount connector (model SM06B-SRSS-TB). You mayobtain technical information on these PCB-mount mating connectorsfrom the JST Web site: http://www.jst.com/.Note: Unless otherwise specified, all references to the GPS 18 LVC also include the GPS 18 LVC-5m.
