CAUTION: The CAT-5 connector on the side of the Smart-Trak 2 is NOT an
Ethernet connector. Do not plug an Ethernet cable here as damage may result.
All electrical connections for your Smart-Trak 2 instrument are made on the left
(inlet) side panel.
Figure 5-1: Smart-Trak 2 Connections
If you do not have the Pilot Module display, you can connect pins 7 (serial
transmit), 13 (serial receive) and 3 (analog ground) on the instrument’s 15-pin mini-
D Connector to an appropriate serial port using a standard DB-9 connector instead
of using the supplied CRN cable (see Chapter 2 for wiring instructions). If you use
the mini-D connector for your RS-232 communication, please shield the cable to
prevent EMI from disrupting communications.
