placed at pins 7 & 8 is the GPS port. Refer to Table 17: DB9 Serial Y Splitter Cable Pin Connections and
Table 29: RS-232 Serial Port DB9 Pin Assignments for the pinout of the DB9 connector.
The DB9 Serial Y Splitter Cable, part number W6001, is available to attach to the DX-2200 DB9 connector
and provide two separate DB9 (female) sockets with one port on each connector. This cable may provide a
more convenient connection of the Control Port device and also the GPS to the DX-2200. The cable is not
supplied standard with the DX-2200. It must be ordered separately.
Figure 21: DB9 Serial Y Splitter Cable (Part # W6001)
GPS receivers will typically not have the required DB9 connector attached to the data cable and it will be
necessary to install the connector. The wiring of the GPS receiver to the DX-2200 will depend on the model
of GPS receiver that is used. Refer to the GPS receiver documentation for details.

An example connection is shown in Figure 22 for the Garmin GPS18x LVC Receiver. The example uses the
COM Port DB9 Serial Y Splitter cable. Note that if the splitter cable is not used and the GPS receiver is
wired directly to the DB9 on the DX-2200 instead, different pin numbers must be used. Instead of wiring the
green and white wires to pins 2 & 3, use pins 8 & 7. (Refer to Table 29: RS-232 Serial Port DB9 Pin
Assignments.)
The DX-2200 does not provide power for the GPS, therefore an external power source or battery operated
GPS will be required.
