Installing Universal D-Box
The D-Box provides an interface between Gilbarco consoles with TWI and third-party
controllers with RS-422 interface and dispensing units, CRINDs, or G-CATs. The PCB(s)
inside the D-Box includes jumper jacks which are used to select either the TWI or the 
RS-422 configuration. The required interface connector(s) to the controller is provided, with
the D-Box.
Note: Interface cables between the D-Box and the console/controller are not included, and
must be ordered separately. For proper length and type of cable required, refer to
“Data Cabling Requirements” on page 17.
The D-Box houses the power supply transformer and a removable tray with either one or two
PCBs. Each PCB contains a power supply, an opto-coupled current loop interface, an RS-422
interface, eight dispenser current loops, and automatic isolation circuitry.
Two four-channel MTA connectors are provided for each circuit board for field wiring 
(see Figure 8 on page 20). These are required only for T17651-G1 Boards. For M14301AXXX
Board, field wires are directly terminated on box type connectors on board.
The Transac System 1000 and PAM 1000 controllers require this D-Box. One D-Box is
needed for every 12 fueling positions (Transac System 1000 systems with three or four
consoles require an additional D-Box).

MDE-2713C Universal Distribution Box (D-Box) Installation Manual · August 2016 Page 7
Installing Universal D-Box
D-Box - Controller Interface
D-Box with T17651 PCA
There are eight individual current data loops for dispensing units on each distribution board
(see Figure 1 on page 8 to Figure 6 on page 13). D-Box with two boards can be configured as
either:
• Two separate inputs with each input controlling eight data loops [see Figure 1 (iii) on
page 8 and Figure 3 (iii) on page 10], or
• One input controlling 16 data loops [see Figure 1 (ii) on page 8 or Figure 3 (ii) on
page 10].
Each data loop has both current regulation and automatic isolation circuitry. The dispenser
data loop drivers operate from an unregulated 12 VDC supply at 45 mA for Gilbarco
dispensers and CRINDs, or 20 mA for G-CATs. The applicable configuration is set by jump
jacks on the distribution board(s) (see Figure 9 on page 20 to Figure 24 on page 20).
Each distribution board must be dedicated for use with either Gilbarco dispensing units,
CRINDs, G-CATs, or consoles (for Transac System 1000 multiple consoles). Do not mix
different current loop equipment on one distribution board.
D-Box with M14301 PCA
There are 16 current data loops for dispensing units on each board. This board can be
configured as either:
• Two separate inputs with each input controlling eight data loops [see Figure 2 (iii) or
Figure 4 (iii)], or
• One input controlling 16 data loops [see Figure 1 (ii) or Figure 4 (ii)].
When installing equipment, ensure that the boards are configured for 20 mA current loops if
connecting G-CATs to the D-Box. Damage to the G-CAT MPU boards will occur if the jump
jacks are not set correctly.
When installing equipment, connect only one dispenser or card reader to any one data loop
channel. The wiring length between the D-Box and dispensers must not exceed 2600 feet, and
requires stranded or solid 14 American Wire Gauge (AWG) wire. Do not use daisy chaining
with this unit.
For Transac System 1000multiple console installation, refer to MDE-2538 Pigtail Two-wire
Cable Kit K93391-01.

Preparing for Installation
Unpacking Equipment
When the equipment arrives at the installation site, each unit should be unpacked and
inspected for possible shipping damage. If damage is evident, it must be reported to the carrier.
Shipping damage is not covered under Gilbarco’s warranty policy. After visual inspection,
place the unit back in its shipping carton to prevent undue exposure to the elements, and store
indoors until ready for installation.
Returning of Components
Components returned to Gilbarco under warranty or for repairs are subject to severe shipping
damage if not packaged properly. If original packing materials are unavailable, use a durable
reinforced corrugated box and obtain suitable packing material such as “PAKON” polyfoam
chips, polyurethane foam chips, or polystyrene foam chips. Fill bottom of box with at least 
2 inches of packing material. Ensure that the component is firmly packed. It is also
recommended that the package be fully insured.
All returned items must be accompanied by a Returned Goods Authorization (RGA) form.
Remember to include return shipping information and a description of the malfunction.
Note: If the component arrives at Gilbarco in a damaged condition and it is ascertained that
the damage was a direct result of improper packing, such damage will not be covered
under the original factory warranty and the customer will be held responsible for the
cost of the repair necessary to correct said damage.
Basic Site Criteria
Installation of the D-Box must be in accordance with the NEC NFPA 70, the Automotive and
Marine Service Station Code NFPA 30A, and any state or local electrical requirements.
For Canadian installations use the Canadian Electrical Code CSA C22.1.
The site must be equipped with electric service allowing compliance with all installation
requirements of a complete fueling system.
An enclosed weather-protected structure must be located on the site for housing the D-Box.
Room ambient temperature must not exceed 130 °F (55 °C). This maximum temperature is
allowed only if the equipment is allowed free air flow.
Megger testing of field wiring must be completed prior to connecting wires to the D-Box.
The data cabling between the D-Box and the system controller must be kept separate from all
other power and control lines.

Installing Universal D-Box

Allow several inches clearance on the left side of the D-Box for the AC power cord. Allow 
2 inches clearance above the box for removing the cover.
Electrical Wiring Requirements
The receptacle providing power to the D-Box must be a properly installed isolated ground
receptacle (Hubbell #IG5261 or equivalent). This type of receptacle is easily identified by its
bright orange color and by the triangle embossed into the face of the outlet. The green
grounding screw must be attached to the grounding conductor.
• All electrical wiring must conform to NEC and local wiring codes, as well as the criteria in
this manual.
• One conduit from the breaker panel to the D-Box location is required. The conduit must
contain three 14 AWG wires: 115 VAC Hot, Neutral, and Ground; or 230 VAC L1, L2, and
Ground. Do not use the electrical conduit to provide earth ground.
• The circuit powering the D-Box must not power other devices. This circuit must not share
a conduit with wiring for devices drawing high amperage (compressor, freezer, etc.) or
devices that are sources of Radio Frequency Interference [RFI (TV, microwave, intercom,
etc.)].
• The AC outlet must be within 6 feet of the D-Box (see Figure 7 on page 17). Do not use
extension cords.
Note: For 230 VAC operation, a 9 feet detachable line cord is provided. It is the customer’s

Field Wiring Requirements
A wiring trough will be 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 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 will be needed
inside the D-Box.
When pulling wires, be careful to avoid damage to the insulation.
Installing D-Box
To install the D-Box, proceed as follows:
1Loosen two screws on bottom front of D-Box and lift lid.
2Carefully remove and discard any packing material from D-Box.
3Disconnect cable from the distribution board(s) T17651 at P101 and P102 (or P103). Also
disconnect wiring pigtails from P106 and P107. In case of M14301 Board, cables will be at
P101 and P102A/B (or P103A/B). For connector locations, refer to Figure 10 on page 21.
Working on PCBs without connecting to a ground or discharging static can damage
electronic parts. Use a wrist strap and store parts in antistatic storage bags.
CAUTION
4Slide mounting tray [with circuit board(s)] up and out of the D-Box.
Note: The boards are removed to avoid unnecessary damage to components while mounting
the unit to the wall.
5Mount D-Box to the wall.
• Allow clearance on left side to connect AC cable.
• Allow clearance above the D-Box so that the cover can be removed.
6Mount AC receptacle within 6 feet of the D-Box.
7Install conduit for data wires between the wiring trough and the D-Box. Pull data wires up into
the D-Box leaving 16 inches of wire inside the D-Box. This allows for easy installation of
wiring pigtails.
8Connect data wires to wiring pigtails. In case of M14301 Board, wires will be directly
terminated on box type connectors whereas in case of T17651 to wiring pigtails (see Figure 8
on page 20).
9Replace mounting tray [with circuit board(s)]. Reconnect cables as required to the circuit
board(s). For T17651 Board, reconnect P101, P102 or P103, P106, P107. For M14301 Board,
reconnect P101, P102 A/B or P103A/B.

10 Connect data cable(s) to 9-pin D-Sub connectors. In case of T17651 Board, plug MTA Pigtails
to the circuit board(s). In case of M14301 Board, connect cables directly to box connectors
present on board.
11 Verify that the jump jack settings are correct for your configuration. For correct jump jack
configuration, refer to “Jump Jack Configuration”.
Note: When installing the universal D-Box for a RS-422 application (Passport), jump jack
JP9 must be installed for the correct hardware configuration. Configure jump jack JP9
for 45 mA current loop for CRINDs/dispensers and 20 mA for use with G-CAT2 and

G-CAT 3.
