Data Communications:
The Wireless Communication Interface can receive data
communications through one of two wiring media: either
RS-485 half-duplex or RS-232. Before wiring, determine
which data communication wiring medium is to be tied to
the Wireless Communication Interface and proceed as fol-
lows (Refer to Setup section for further explanation).
1) RS-232 Connection (if applicable):
(See Figure 8) A

Silo
Track
/PC system can be connected
directly to the Wireless Communication Interface using
the PC’s RS-232 serial port. RS-232 is intended for
use in office environments where interconnection dis-
tances are short (less than 12 feet) and where heavy
electrical circuits (motors, contactors, etc.) are not
present. The interconnection must be done point-to-
point (no multi-dropping or networking) with a 3-
conductor cable (such as Belden 9533 or Alpha 6303).
Determine the type of connector on the PC, source a
suitable mating connector (See Table 1) then intercon-
nect as described in Table 2.
