3.3 CONNECTION WIRING DESCRIPTION
The GPS 35/36 features a stripped and pre-tinned cable
assembly for the greatest connection flexibility. The following
is a functional description of each wire in the cable assembly.
Red: VIN - Unregulated 10 - 30VDC 200 mA
(maximum). Typical operating current is
150 mA.
Black: GND - Power and Signal Ground
White: TXD1 - First Serial Asynchronous Output.
RS-232 compatible electrical specification.
This output normally provides serial data
which is formatted per
“NMEA 0183,
Version 2.0”
. Switchable to 1200, 2400,
4800 and 9600 BAUD. This output functions
in parallel with the NMEA output.
Blue: RXD1 - First Serial Asynchronous input.
RS-232 compatible with maximum input
voltage range-25<V <25. This input may
be used to receive serial initialization/
configuration data, as specified in Section
4.1.
Purple: TXD2 - Second Serial Asynchronous
Output. Electrically identical to TXD1.
Green: RXD2 - Second Serial Asynchronous Input.
Electrically identical to RXD1. This input
may be used to receive serial differential
GPS data formatted per
“RTCM
Recommended Standards For Differential
Navstar GPS Service, Version 2.0”
(see
Section 4 for more details).
Gray: NMEA-NMEA0183, Version 1.5 electrical
specification compatible serial output.
This output is also CMOS compatible with
