Connecting the GPS 310 to an Autopilot Device
To connect the GPS 310 to an autopilot or other external
device you may need to cut off the DB9 connector and “hard
wire” the cable to the device. The cable configuration is as
follows:
Orange: Data Out
Yellow: Data In
Black: Ground
Red: Power (DO NOT USE)
Refer to the manual on the external device and connect the
wires to their proper place. Be careful and double check your
connections before applying power to the external device as an
improper connection could damage the GPS 310 and void its
warranty.
Connecting the GPS 310 to a DGPS Receiver
The GPS 310 is capable of receiving differential corrections
from a differential receiver for improved accuracy. By
connecting a differential beacon receiver (DBR), such as the
Magellan DBR IV, to the GPS 310, corrections are automati-
cally applied to the position and velocity computed by the
receiver. If corrections are being applied to the GPS 310,
“DGPS” will appear on the top of the position screen.
The GPS 310 accepts standard RTCM v2.1 messages at 4800
baud rate. You can use either the Data Cable, Power/Data
Cable or PC Cable with Cigarette Lighter to connect the GPS
310 to the DBR.
