5. Clear memory, if necessary.
The following paragraph tells you how to clear the memory in
the MAP. Follow these instructions
only
if you are installing
the MAP in a system for the first time or if you need to clear all
memory.
The MAP has a battery-backed memory that can retain system
configuration in the event of a power interruption to the MAP.
To clear the memory, follow these steps:
♦
Set switch S5-7 in the UP position (refer to Fig. 10).
♦
Plug the MAP into your system and apply power.
♦
Wait ten seconds, then turn off power to the MAP.
♦
Remove the MAP from the system and set switch S5-7 in the
DOWN position.
6. Configure the system.
Before you can use the system to poll remote devices, you must
specify how you want it to operate. Without this configuration
step, the system will not poll. Refer to the
Switch Settings
chapter.
Before making connections, refer to the block diagram that
comes with the shelf.
7. Test the system.
Once you have configured the system, test it for proper opera-
tion:
♦
Apply power and perform a simple operation check-out. If
the MAP is communicating through the data port, the XMT
DATA light on the front panel will be blinking.
♦
Create some alarms. Observe that the correct responses are
going through the master or printer port to the alarm center
or to a standard ASCII terminal connected to the printer
port.
♦
Operate some control points and verify correct operation.
If the MAP does not function properly, check the following:
♦
Switch settings and/or the communications wiring at the
MAP slot.
♦
Switch settings on modules the MAP is communicating with.
