12 Tokheim Pump Interface Manual v1.3
Gasboy CFN Series 03/20/03
Mode 26
Mode 26 in the Tokheim pump must be set to 1, if the dispenser is a blender. For the Premier,
mode 26 should be set as 2.
Mode 29
Mode 29 (DPT Keyboard programming) does not have to be set up. However, you may want to
program the START key so the pump can operate in stand-alone mode when the DPT is down.
Under normal operating circumstances, the Site Controller will download this information which
was configured in SYS_PAR.
Tokheim 98 Box Resistors
The following changes are necessary for the CFN3 or SCII without a splitter. Make the following
connections inside the 98 box:
• TALK DISP should be connected to +9V with a 1K Ohm resistor.
• DC COM should be connected to GND.
Tokheim Splitter
The Tokheim Splitter, which requires SCII version 2.0b or later, is part number is C05851. For
complete installation information, please refer to the Site Controller II Installation Manual.
For CFN3 the splitter is built into the boards, you do not need this part.
SCII - Interfacing to Tokheim pumps via a Tokheim Splitter
The Tokheim splitter (P/N C05851), along with the proper cabling, allows up to 32 electronic
pumps to be controlled through one SCII communication port (port 1 or port 3). The Site
Controller must be running Version 2.0B for channels 1 and 2 on the splitter to be used. If a site is
running Version 1.0 software then only channel 1 can be used.
A Tokheim 67 box controls the 262, 262A, TCS, and Premier families.
The 67B is a standard 67 box is configured for operation with a VX100 or VXDHC. This
box works in the 422 mode when talking between the a 67 box and the Controller. The 67B box
must be converted back to a standard 67 box to operate correctly.
The Tokheim 98 box controls the 162, dumb MMD’s, mechanical pumps, etc. By using a 67
or 98 box, the Tokheim splitter can interface to all of the previously listed Tokheim electronic
pumps.
The splitter is not needed for a Tokheim 69 box which has a totally separate communication
line which controls the Premier/TCS DPTs.
Site with Single Tokheim 67 or 98 Box - requires a C05578 cable assembly. This assembly
includes the Tokheim splitter (C05851).
Site with Two Tokheim 67 or 98 boxes - requires a C05876 cable (dual channel). This assembly
includes the Tokheim splitter (C05851).
Site with More than two Tokheim 98 boxes - requires a C06694 assembly to supply the correct
cabling. It consists of one C05851 (splitter), one C05878 cable, and two C05577 cables.
