PI DBox — Model Specific Installation
RS485 Style — RS485 DBox
Note all warnings in System Installation Warnings section.
RS485 Style PI DBoxes are used with Wayne CAT card reader, Tokheim DPT, Tatsuno dispenser, and
Nuovo Pignone dispenser. Note dispenser-specific instructions for use with each dispenser. For
overview, see RS485 diagrams 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. Dispensers using RS485 communication have three wires for
connectivity: +, -, and ground. For each RS485 dispenser being connected, bring dispenser
wires into the PI DBox and connect to +, -, and ground on an unused wiring position. Ensure
that wires are not crisscrossed at the DBox, as this will prevent communication with the
controlling device. Connect no more than four physical devices in each of the four groups of
connections (1-4, 5-8, 9-12, and 13-16). Two device addresses are equivalent to two
connections.
2. To connect to a PIE console over the PI DBox’s PiPort proprietary link, use PIE’s 9000 15
0034 cable. Jumper J6 must be set for LB. Jumpers J8 and J10 must both be jumpered for
PiPort. Jumper J3 should be set to GND. If connecting to PIE’s FuelDirect Fuel Control
Solution using the RS232 port, set J8 to /txd and J10 to RSTxd. If connecting to FuelDirect
using ethernet, set J8 and J10 to XPort. (Refer to IP Addressing section at end of this manual
for further instruction on ethernet connectivity.)
3. Proceed with programming of system.
