PI DBox — Model Specific Installation
Tokheim Style — Tok-DBox
Note all warnings in System Installation Warnings section.
Tokheim Style PI DBoxes are used with Tokheim dispensers. Note dispenser-specific instructions for
use with each dispenser. For overview, see Diagram: PI DBox — Tokheim Style on following page.
Follow instructions in the installation section of the accompanying product manual before connecting
PI DBox as follows:
1. Connect PI DBox to dispenser. Tokheim dispensers have three wires for connectivity: TTD,
TTC, and DCC. For each Tokheim dispenser being connected, bring dispenser wires into the
PI DBox and connect to TTD, TTC and DCC on an unused wiring position. Ensure that wires
are not crisscrossed at the DBox, as this will prevent communication with the controlling
device.
Note: A recent DBox board redesign has eliminated the need to set Isolate Jumpers. For Tokheim
DBoxes with an Assembly Number of 900-11-6412, proceed to Step 3 in this section. If installing a PI
DBox with an Assembly Number of 900-11-6312, follow instructions in Step 2.
2. Note that above each wiring position in the PI DBox, an isolation jumper is present (positions
J2-J5 and J7-J10). Leave these jumpers in isolate position until the controlling devices are
connected to the DBox. After connecting all dispensers to be used, move jumpers to normal
for each position connected. Refer to Diagram: Key Components of PI DBox — Tokheim
Style.
Note: Steps 3-5 in the Tokheim -Style installation procedure are dependent upon the type of
application — PIE application or stand-alone application. Give careful attention to which steps are
needed for your particular application. Also, refer to the appropriate drawings for jumper settings,
interface connections and dispenser wiring.
For applications using PIE products:
For stand-alone applications, see description later in this section.
3. Set the jumper on JP2 to the interface type to be used. The PiPort interface is used by the
PIcon Console. The RS232 and Xport are used by the FuelDirect Fuel Control Solution.
