External Differential Connection

Differential corrections from an external beacon receiver can only be
connected to either the MX421-10 or the MX521/MX525 GPS model.
Connections are done directly through Pins 7 (yellow) and 8 (white) of
the antenna cable for the MX421-10, and Pins 9 (purple) and 10 (grey)
of the antenna cable for the MX521 and MX525. It will accept the
RTCM SC-104 signal at 2400, 4800, 9600, or 19200 baud.
