OPERATION
MAP O
PERATION
T
he front panel of the MAP has a green LED labeled XMT
DATA. This LED flashes when data is being transmitted
from the data port.
On the front panel of the MAP, there is a recessed reset button.
When you push this button, it executes a complete, or hard,
reset. The effect is the same as removing power from the MAP.
When power is restored later, the information in the MAPs
memory is saved ...
only
if you have set the switches to retain it
(see
Switch Settings
). If you have not set the switches to save
the memory, it will be erased.
For operation of the printer port using Printer Syntax, see the
Printer Syntax
chapter.
If you install a subassembly on the master port, refer to the
subassembly manual for operation information.
MAC O
PERATION
The MAC may be used to display alarm and communication
status. The firmware affects the operation of the LEDs and
switches on the 46022-12 MACs. The following operating in-
structions apply only when this firmware is used in a MAP that
is operating with a 46022-12 MAC.
Applications
One MAC front panel has a capacity of 32 displays (See
Fig. 16). This represents 2,048 alarm and control points.
Through the use of function switches, the MAC front panel
reports individual alarm point status.
If the MAP communicates with more than one MAC (whenever
more than eight serial ports are needed), only the number one
MAC provides all front panel functions. Other MACs provide
only communications status reports for their own ports.
