8.3.2. Connecting the Serial Port
Connect a straight-through RS232 cable (shipped with unit) to serial 3, 4 or 6 (if the additional AUX I/O
breakout is connected to the EMC). The other end of the cable will connect to the EAS decoder. (See
the section specific to your encoder manufacturer). For a permanent installation, you will require a
custom length cable that fits between the EAS decoder unit and the EMC. You can purchase any off the
shelf 9 pin straight-through serial cable, or you may make this cable yourself according to the cable
drawing in Table 8-2. This cable should not exceed 50 feet. Note that an RS232 serial port on the
EMC must
be used.
