GPS 18 SERIES
There are several different versions of GPS 18 available. Refer below for a list of the three major divisions
of the GPS 18 Series.
of the GPS 18 Series.
1.4.1
GPS 18 USB
The GPS 18 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. 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.

1.4.2
GPS 18 PC
The GPS 18 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.

transmits voltage levels that swing from zero V (ground) to 5 V
TIA-232-F (RS-232) polarity.
The GPS 18 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 18 as a serial
mouse. Please refer to

1.4.3
GPS 18 LVC, GPS 18 LVC-5m, and GPS 18-5Hz
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

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
