running the wires are easy since all data communicates on either 2 or 4 wires depend-
ing on the protocol.

If the fueling system is to consist of only serial protocol dispensers, use the Site Prep
Checklist on the following pages instead of the standard site prep checklist. However, if
the system combines serial protocol dispensers and direct wire dispensers, use the
general site prep checklist and item 1 from the site prep checklist for serial protocol dis-
pensers.

Refer to the Field Wiring Diagram for Tokheim/Krause Serial Protocol Dispensers
(below) as a guide for connecting the M3000 with these types of dispensers.
