Preliminary Preparation
Data Cabling Requirements
For the correct controller to the D-Box data cable, refer to
.
Neatly install all cables so that they are protected from damage or accidental disconnection.
Route the cables along a wall or under a counter and secure with cable-ties or suitable cable
clamps.
Do not route data wires over fluorescent light, compressor wiring, etc., nor within 12 inches of
electronically noisy devices, such as variable speed STP controllers or associated wiring.
Use a 9-pin D-Sub receptacle to 8-pin Modular Jack Gender Mender (Q13180-11) to convert
the Transac System 1000
™
console 9-pin plug D-Sub on underside panel to modular jack
receptacle to connect the cables above. That can also be used for pre-existing sites on end of
molded D-Sub cable if that cable must remain due to difficult prior installation.
Field Wiring for Data Cables
Use the following modular jack parts for field wiring:
Number
Description
Q13241-01 In-line 8-pin modular jack receptacle to receptacle coupling.
Q13241-02 Wall-mount single 8-pin modular jack receptacle to field wiring.
Q13241-05 3-way splitter
Note: Use 14 AWG stranded or solid wire between wall receptacles.
Field Wiring Requirements
A wiring trough is required in the vicinity of the D-Box for terminating the conduit runs from
the dispensers. Three 1-inch knockouts are provided on the bottom of the D-Box for running
conduit between the box and the wiring trough.
Use 14 AWG stranded twisted-pair wire for data wires to Gilbarco dispensing equipment.
Leave plenty of wire exposed as a service loop in the wiring trough. 16 inches of exposed wire
is needed inside the D-Box.
Note: In the main conduit, for communications use only twisted-pair, two-wire data pairs. Do
not use shielded wire.
Unshielded Twisted-pair (UTP) wire is required for two-wire communication wiring for new
installations. Previously wired stations may continue to use tested existing non-twisted pair
wiring that has been tested for short circuits and continuity and passed. However, twisted pair
wiring is recommended for existing wired stations known to have communications problems
between the console and dispensers.
When pulling wires, be careful to avoid damage to the insulation.
