ELECTRICAL INTERFACES
Introduction
This section gives the pin assignments for all connector interfaces used on the CashFlow
®
validators and it also includes timing diagrams of the signals appearing on the input and
output lines.
Connector 1, Machine Interface.
The interface to the validator from the machine is exactly the same as those that apply to
the MS/ME series validators, with the exception of pin 8 of the 17-way connector.
Connector 1 can accept either 15 pin or 17 pin interface connectors.
