FEATURES
You can program the year, month, day, hours, minute,
and second for the main unit. All modules derive their
time from the base unit's time-of-day clock. You can
also program the Unit Number from 1 to 30.
5.2 BASE UNIT BASIC OPERATION
The M Series base unit acts as a switch between the
host control module(s) and the I/O modules. The base
unit also allows configuration for the entire M Series
system from the service port or service modem and
limited configuration from the front panel.
The base unit contains the system power supply (M8 &
M16 only), an optional LCD display with front panel
controls (optional on M8 & M16), or LEDs (available on
all units), a service port, an optional service modem, a
main unit PC board with system control firmware and
time-of-day clock(optional on M3 & M4), multiple
expansion slots for host control modules and I/O
modules, a POWER LED, and a power ON/OFF switch.
When the unit is powered up, the POWER LED
illuminates. Units equipped with LEDs go through a self
test before the LEDs turn off. Units equipped with LCD
and front panel controls scroll through several menus as
shown below and on the following page for the M16.
