INTRODUCTION
This section explains the inputs and input circuitry, control
logic, logic power and connections for the Pulse Input Slave
Module (DSM). The DSM is a digital input interface to a
Multi-Function Processor (MFP) module. The slave has eight
pulse input circuits that condition process signals, see Figure
. Input signals are processed, stored and sent to the master
module. The master module communicates with its slave mod-
ule on a 12-line slave expander bus shown in Figure
. Each
slave on the slave expander bus has a unique address set by
the slave address dipswitch.
