1.3 Internal Architecture
The TT8900 OPT is based on the next gen TT Fuel proprietary
modular T20 Dispensing Control System architecture, ensuring
maximum reliability and operational uptime.
The T20 DCS comprises of a range of modules that each provide a
dedicated set of functions and features that together provide a
multitude of solutions for various fuel dispensing control and
management applications.
These systems are all supported by a suite of
enterprise-level fuel management software
applications and web-services developed by TT Fuel
to form complete fuel dispensing control and
management solutions.
The T20 DCS modules share a common form-factor utilising a DIN rail mountable compact
enclosure system interconnected using TT Fuel’s proprietary HBus communication bus system.
The TT8900 OPT incorporates the following key modules:
»T20 System Control Module (SCM).
Conceptually similar to the former T6 Controller, this module is the next-
gen forecourt control unit, consequently the brain of the TT8900 OPT.
»T20 Terminal Support Module (TSM).
Specific to the OPT, this module combines the functionalities of CAS, PSM
and EIM.
»T20 Internal Interface Module (IIM).
This module is used for configuring the TT8900 OPT whenever
configuration via remote connection cannot be established.
»Cellular Router
This module provides secure connectivity to the TT Fuel’s back-end
services through the existent cellular network.
»Optional T20 Protocol Converter Modules (CGM / DGM / CNM) used to interface with
forecourt control systems using alternative communication network protocols.
Additionally, the TT8900 OPT accommodates the following internal components:
»AC/DC power supply.
»DC UPS.
»Battery pack.
»PINpad and display.
»Card reader.
»Receipt printer.

1.4 Tandem Configurations
Depending on the particularities and requirements of some
installation sites, the TT8900 can be deployed in tandem
configuration, having a primary OPT driving one or more
secondary OPT units.
The secondary OPTs lack the T20 SCM forecourt control unit
found in the primary OPT, therefore any peripherals a refuelling
site might have, such as Automatic tank Gauging or a Price Sign
can only be connected and controlled through the primary
TT8900 OPT.
Note: Secondary OPTs have a slightly different External Connections Label, applied inside the
unit, as covered in chapter 2.13 Forecourt Connections.
1.5 Offline Modes
Dealing with authorising electronic payments, the TT8900 OPT default mode of operation is the
Online Mode, where all transactions are validated in real time, through its permanent Internet
connectivity.
However, if Internet connectivity gets disrupted, the TT8900 OPT automatically switches to one
of its Offline Modes. Each having a distinctive behaviour, there are a total of 7 Offline Modes to
choose from prior to deployment, by filling in the Offline Mode Application Form.
Offline Mode
Description
Online Only
The only authorisation method accepted for any transaction is Online Mode.
Any Internet connectivity disruption will render the OPT unusable.
Retail 1
Total exposure is limited to the Total Offline Transaction Limit. Exposure
per Id is limited to the Transaction Number Limit multiplied by the Floor
Limit.
Retail 2
Total exposure is limited to the Total Offline Transaction Limit. All Ids can
run up the daily dollar limit each day the system is offline.
Commercial 1
The exposure per Id is limited to the Transaction Number Limit multiplied
by the Transaction Volume Limit per Id.
Commercial 2
All Ids can run up the daily volume limit each day the system is offline.
Basic 1
A basic offline authorization mode that disallows active Ids that haven't had
recent use. Offline authorizations are not subject to volume, amount or
frequency limits.
Basic 2
A very basic offline mode that has no refuelling restrictions. Offline
authorizations are not subject to volume, amount or frequency limits.
Note: Electronic payment authorisation can fall back to an (previously agreed on) offline mode
for local account cards only. Consequently, the only authorisation method accepted for bank
issued cards is Online Only.

2. Installation
This section must be read and understood prior to any installation or servicing work
commencing. For further clarifications, please contact Transponder Technologies.
For installation activities, it is assumed the installer possesses previous expertise and training
in Transponder Technologies equipment, particularly T6 Controller based DCAs and Forecourt
Controllers.
Tools Required: The only non-standard tools required to install the OPT is a Post Torx
(also known as Tamper proof Torx) size T30 security screwdriver. This is for the M6
screws that secure the access panel.
2.1 Standards and Safety
It is the responsibility of the installation staff to ensure that all relevant standards and
legislation relating to installation of this device are adhered to e.g. OH&S, electrical wiring codes,
and hazardous area works etc.
2.2 Applicable Standards
The following is a list of some of the standards that are relevant to the installation of the OPT.
Note: This list is NOT complete and the installation technician is responsible for determining
what other standards may apply.
»AS 3000 “Wiring Rules”.
»AS 1940 “The storage and handling of flammable and combustible liquids”.
»AS/NZS 2430.3.2 “Classification of hazardous areas” “Part 3.2: Examples of area
classification –Vehicle workshops, vehicle parking, fuel dispensing stations and aircraft
hangars”.
2.3 Safety Issues
This list is provided as a guide to some of the product specific safety issues that need to be
addressed when installing this device. It should not be considered complete.
»The complete TT8900 OPT tower weighs approx. 140kg, therefore handling precautions
are required.
»The upper cabinet assembly weighs approximately 30kg. Two people should be used
when lifting it into position within the tower.
»The TT8900 OPT has an internal Uninterruptable Power Supply (UPS). This means that
even if the device is isolated at the switch board, there will still be voltages present
inside. Before operating on the device, the UPS should be switched off using the switch
located on UPS battery pack and the UPS battery should be disconnected.
»The door assembly of the TT8900 OPT weighs approx. 10kg. The oil filled struts that
prevent the door from opening too quickly, and restrict its travel, should be inspected
regularly to ensure that they are working and are fastened to the door and cabinet
securely.

TT8900 OPT –Installation and Service Manual
Page 12 of 41
»When the door is open, the corners of the door represent a hazard particularly if
someone is working inside in the lower section of the tower enclosure.
2.4 Installation Guidelines
It is recommended that the 240VAC supply to the OPT come from a separate circuit that is
protected by an RCD. Local electrical standards must be adhered to when selecting these
devices.
Where possible, the 240VAC feed line to the OPT should not be used for power to other high-
current or “noisy” electrical devices e.g. pumps or dispensers.
Steps to be completed:
»Pre-installation site survey including signup for a Merchant account with the bank.
»Site preparation, including cabling and installation of required services.
»The actual hardware installation.
»Electrical connections to, and inside, the OPT cabinet.
»Initial power-on check.
»OPT forecourt configuration check.
»PIN Pad bank logon check.
»Testing of all connected components on the forecourt.
»Pump calibration / NMI certification and site commissioning.
»Operator Training.
Location Considerations
The following aspects need to be considered when selecting a location for the OPT. This list is
not exhaustive and the site surveyor should also consider any other criteria that may come from
the customer or from legislative requirements.
»Needs to be installed outside of the applicable hazardous area. Transponder
Technologies recommend that the OPT is installed at least 1m outside the reach of any
fuel dispensing nozzle even if this is further away from any dispenser than what the
applicable standard requires.
»Should be shaded from the sun (particularly the aluminium fascia) by a suitable external
structure. This is to help keep the internal temperature of the unit down and to prevent
the metal surfaces of the OPT from becoming too hot to touch.
»Users must not be unreasonably exposed to danger from moving vehicles, either while
using the OPT or while approaching it.
»Should be sheltered from high winds and saltwater spray.
»Should not be installed where water is likely to pool or flood.
»If the OPT is at risk from being struck by a moving vehicle, then bollards should protect
it.
»The mounting plinth should be installed so the top side is clear of the surrounding ground
to provide an adequate water barrier, but not so high that the PIN Pad is too high for
shorter users.
»If the OPT is to be used at night, then adequate lighting should be provided (as per AS
1940). These suggestions are based on the industry best practices and our technicians’
hands-on experience.

2.8 Supporting Cabinet Installation
Once the plinth is installed, the supporting cabinet can be lifted onto the plinth and bolted down
with the supplied fasteners as shown below.
Note: Recommended tightening torque is approximately 40 Nm (30 foot-pound or 360 inch-
pound).
2.9 Installing the TT8900 OPT inside the Optional Supporting Cabinet
Once the supporting cabinet has been fastened to the plinth, follow these steps to install the
TT8900 OPT into the supporting cabinet:
1. Using two people, one positioned each side of the supporting cabinet, lift the TT8900
unit up to the level of supporting cabinet’s aperture and rest it on the internal supporting
shelves inside the supporting cabinet.
2. Carefully slide the TT8900 OPT unit inside the supporting cabinet until it stops –at this
point the hole-plugs in the bottom of the TT8900 OPT unit will have come up against the
bottom shelf of the supporting cabinet.
3. Lifting the front of the TT8900 OPT and sliding it in will allow the hole plugs to clear and
the unit to be fully inserted.

Important: Take care that the sides of the aluminium door bezel do not scrape the inside
faces of the supporting cabinet when inserting the TT8900 OPT unit.
4. Looking inside the supporting cabinet and up at the bottom of the cabinet, roughly align
the mounting holes in the bottom of the cabinet with the round holes in the support
shelfs.
5. Insert the bolts and washers into the mounting holes of the support cabinet as shown in
the diagram below. Do not tighten the bolts at this stage, tighten by hand only.
6. Pull the TT8900 OPT unit towards the front of the supporting cabinet until the mounting
bolts prevent it from coming any further forward.
7. While looking at the front of the TT8900 OPT, ensure that the aluminium bezel is sitting
square inside the supporting cabinet aperture and that the gap between the bezel and
the side faces of the aperture is the same on both sides.
8. Once the TT8900 OPT unit is correctly aligned, tighten the mounting bolts.
9. Open the TT8900 OPT door and check it doesn’t scrape the sides of the supporting
cabinet and that it opens fully without obstruction.

2.10 TT8900 OPT Cabinet Cable Entry Holes
The TT8900 OPT Internal Cabinet has provision for cable entry via seven holes located in the
base of the cabinet. The holes accept a standard plastic or metal 20mm cable gland.
Note: Unused holes must be fitted with blanking covers or sealed with a suitable tape to stop
insects entering the cabinet space.
2.11 Connecting the Power Supply Unit to the AC Mains Power
TT8900 OPT has been greatly simplified, now offering a much more
robust and quicker way to connect it to the mains power.
Follow these steps to correctly connect your TT8900 OPT to the
main power:
1. Route the power cable from the customer’s junction box
inside the OPT, using one of the far-right cable entry holes
(conveniently located next to the PSU, as shown in Figure 6).
2. Connect the Live (brown) conductor on the DIN rail mains
terminal –connector 1.
3. Connect the Neutral (blue) conductor on the DIN rail main
terminal –connector 2.
Figure 5: TT8900 OPT Internal Cabinet Overall Dimensions
Figure 6: TT8900 OPT
Mains Power Connection

TT8900 OPT –Installation and Service Manual
Page 19 of 41
4. Connect the Ground (green - yellow) conductor to the OPT chassis (by first disconnecting
then reconnecting the door grounding cable).
5. Make sure the output voltage is set to +26VDC +/- 0.1, or adjust if necessary, using a flat
head screwdriver.
Note:
The Live and Neutral of the AC mains supply conductors should be fitted with crimp-on boot-
lace ferrules and inserted into the DIN rail mains connectors 1 and 2 as shown in Figure 6.
The Ground / Earth conductor must be fitted with a crimp-on M6 ring terminal and secured
to the earth stud underneath the supplied M6 flat washer and nut on the OPT chassis.
The DIN rail main connector 3 should NOT be used; It is present for test purposes only.
2.12 Connecting the UPS Battery
Follow these steps to mount and connect the UPS battery:
1. Aling the battery’s bottom side of the locking mechanism to
the DIN rail.
2. While pushing the battery upwards, swing the top side
against the DIN rail until it snaps in. (Figure 7)
3. Connect the battery’s cable to the OPT’s UPS.
4. Switch ON its power button.
2.13 Connecting the Cellular Network Antenna
Follow these steps to connect the Cellular Network Antenna:
1. After having secured the Cellular Network Antenna, route its cable inside the
OPT through one of its entry holes.
2. Screw in the SNA connector ensuring it is finger tight.
2.14 Forecourt Connections
The TT8900 OPT comes standard with support for two PEC/NZ pump
communication channels (loops). It can also be optionally fitted with
support for one Gilbarco pump communication channel and/or one Email
pump communication channel.
Alternatively, the OPT can be optionally fitted with a Postec FCC interface
which is an RS232 standard interface. In this case no pump communication
channels are required as the forecourt pump network is connected to the
Postec FCC not the OPT.
All pump communication or RS232 wiring is terminated into the DIN rail
mounted SL protection devices located on the centre of the front DIN rail.
The number and type of SL protection devices fitted to the centre of the
front DIN rail in a particular OPT, and therefore the arrangement of them
on the DIN rail, will depend on whether the following options are included:
Figure 7: UPS Battery
Installation
Figure 8: Cellular
Antenna Connection

TT8900 OPT –Installation and Service Manual
Page 20 of 41
»Gilbarco pump communication channel.
»Email pump communication channel.
»Postec FCC interface.
»Automatic Tank Gauge (ATG) interface.
All standalone or primary TT8900 OPT units are pre-configured from the factory and have the
following label (Figure 9) applied on the inside of their enclosure, displaying the connection
information (marked in green) for the peripherals attached to the OPT (ATG, Price Sign, FCC,
POS).
A separate connection matrix is also present (also depicted in Figure 9), displaying the optional
interface modules (Gilbarco, Email, ATG & Postec) and the channel / serial interface they are
wired to (marked in blue).
Secondary TT8900 OPTs have a slightly different label (depicted in Figure 10) attached on the
inside of their enclosure, displaying the connection information.
Note: For more information regarding a Primary OPT driving Secondary OPTs, read chapter
1.4 Tandem Configurations.
Note: We recommend having all connections fitted with crimp-on boot-lace ferrules before
inserted into the connection terminal. Bare wires (especially multi-stranded) should not be
used with this type of connection terminal.
