For stand-alone applications:
For applications using PIE products, see description earlier in this section.
3. Referring to Diagram: Key Components of PI DBox — Tokheim Style for Stand-Alone
Application, connect using the Tokheim standard proprietary interface of Tokheim RS422
interface. Jumpers J13 and J14 must be configured to correspond to the interface selections
(Std for standard or 422 for RS422).
If connecting through RS422, in addition to selecting RS422 on jumper JP13, jumper
selections on positions JP11 and JP12 should be configured to either invert or not to invert
the RS422 signal. To invert RS422 signal, jumper the 4 pins farthest from labeling of the
position. To choose not to invert the RS422 signal, jumper the 4 pins closest to the labeling
of the position. See Diagram: Jumpering for RS422 Signal Inversion on Tokheim Style for
Stand-Alone Application which follows.
4. If linking dispensers, link through the Link Port of the PI DBox to the next PI DBox. There is a
normal/isolate switch associated with each link. Position JP9 should be jumpered to isolate if
not linking to a second DBox. JP9 should be jumpered to normal for two DBoxes. See
Diagram: Key Components of PI DBox — Tokheim Style for Stand-Alone Applications.
5. Proceed with programming of system.
