CONNECTING TO THE SMART-MR10
Cable connectors are illustrated in
. One DB-9
connector can be used to connect to a PC/laptop serial (RS-232)
communication port. The others can be connected to a modem
or radio transmitter to receive differential corrections (refer to
your user-supplied modem or radio transmitter information for its
connectors). In addition, there are a number of bare wires where
the outer insulation is cut away at the ends to expose tinned
wires. See
for their pinouts. Cables are
RoHS compliant.
The SMART-MR10 cable provides a means of supplying power
from a battery. The bare power wires (red for positive and black
for negative) are connected to a battery capable of supplying at
least 5 W. A 5 AMP fuse must be installed between the positive
terminal of the battery (or power distribution point) and the
positive supply lead of the cable to protect the wiring from short
circuit damage.

RS-232 access to the AUX port and COM1 has no flow con-
trol. If the MODE pin is tied LOW, pins 8 and 22 provide
TXD1- and RXD1- for COM1 RS-422, and the AUX port
(RXD3, TXD3) is not available. If the MODE pin is tied
HIGH, pins 8 and 22 provide RTS1 and CTS1 for COM1
flow control, and the AUX port (RXD3, TXD3) is not avail-
