BASE UNIT AND MODULE OPERATION
BASE UNIT USER-PROGRAMMABLE 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.
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.
The base unit contains the system power supply (M8 & M16 only), LEDs, 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 control switch.
When the base unit is powered up, the power LED illuminates. The base unit
conducts a self test during which the LEDs cycle from the lowest to the highest,
stopping on the CX LED. After a brief moment, several LEDs will light to indicate
the module slots that are currently occupied. These will extinguish and all LEDs will
sequence from the CX LED to the lowest LED. If all modules are operating properly,
all LEDs will extinguish. Any module that is not operating properly will be indicated
by the light for that number module coming on and remaining on.
NOTE: The CX LED may stay on after the self-test if the service port is
connected to a terminal.
Once all module LEDs are out, the unit is in operations mode and ready to accept
commands and/or data. The commands consist of data commands, dynamic
configuration commands, and menu-driven configuration commands. Data and
dynamic configuration commands are issued by a host control module. Menu-driven
configuration commands are issued by a host control module, the service port, or the
service modem.
NOTE: Any modules (except host modules) that are not operating properly
will most likely not affect the other modules. However, the equipment being
tested, switched, or monitored by the defective module will be inaccessible
until the problem is resolved.
