1.5  GPS 18x SERIES 
There are several different versions of GPS 18x available. Refer below for a list of the three major divisions of the 
GPS 18x Series.  
1.5.1  GPS 18x USB 
The GPS 18x USB interfaces to a computer with an available USB port. Drivers 
are available for use on Windows computers. Macintosh and Linux drivers are 
not available from Garmin. After the drivers are loaded, the device appears to the 
Windows operating system as a USB-connected device and appears in Device 
Manager as a Garmin USB Device.  
1.5.2  GPS 18x PC 
The GPS 18x PC interfaces to a serial port of a computer via a DB-9 
connector and receives power through a 12-volt cigarette lighter adapter. 
The unit accepts TIA-232-F (RS-232) level inputs and transmits voltage 
levels that swing from zero V (ground) to 5 V TIA-232-F (RS-232) 
polarity.  
The GPS 18x PC can cause an issue with Windows operating systems if 
the DB9 connector is plugged into the computer before the navigation 
software is up and running. The Windows operating system may 
interpret the serial connector on the GPS 18x as a serial mouse. Please 
refer to 
 for complete details.  
1.5.3  GPS 18x LVC, GPS 18x LVC-5m, and GPS 18x-5Hz 
These products interface to a serial port. The units accept TIA-232-F (RS-232) level inputs and transmit voltage 
levels that swing from ground to the positive supply voltage, TIA-232-F (RS-232) polarity. They also have reverse 
polarity protection. The cable contains wires for power, ground, receive, transmit, and measurement pulse output.  
At the end of the cable, the wires are terminated in a connector that is used 
by Garmin for testing purposes. Most customers will remove this 
connector and replace it with another connector of their own choosing. 
Removing the factory installed connector and/or replacing with another 
customer-supplied connector will have no affect on the warranty (see  
section
). The factory-installed connector will mate 
with JST right-angle PCB-mount connector (model BM06B-SRSS-TBT) 
or side-entry PCB-mount connector (model SM06B-SRSS-TB). You may 
obtain technical information on these PCB-mount mating connectors from 
the JST Web site: 
Note: Unless otherwise specified, all references to the GPS 18x LVC also include the GPS 18x LVC-5m.
