CNI2 Operating and Installation Guide

"Route To" Port Selection in Transparent Mode

Port-1 is the on-board port (or the first channel of the Serial Port Multiplexer board). Port-2 is
the second channel of the Serial Port Multiplexer board.
"Sequential" will cause the CNI2 to select the next enabled port with each call. For instance if
Ports-1,2 and 3 are enabled then Port-1 will be selected on the first call, Port-2 on the next call,
Port-3 on the third call and back to Port-1 on the next call.
With each call the CNI2 will send the following message to the host system:
<cr><lf> CONNECTED TO PORT- xxxxxx<cr><lf>
where "xxxxxx" is the ID of the serial port, <lf> is a line feed character and <cr> is a carriage
return character.

Low Battery Alarm

When the batteries get low the CNI2 will start logging and reporting low-battery alarms to the
data collection system. The voltage level is preset at the factory for most applications. If you
check the "Immediate Call on Low Battery Condition" box the unit will immediately call in
whenever the low battery point is reached. If this box is unchecked then the low battery
condition will be reported on the next call.
NOTE
® ®
Even if the "immediate call" box is checked the data collection system (DC-2009 or MV90 )
has the ability to override it.
The CNI2 will record the time of the day that the alarm event occurred and this time will be
reported to the central office.

Queue Size

The CNI2 can count electrical pulses from up to siz sources although the data collection system
® ®
(DC-2009 or MV90 ) will only accept up to 4. Pulses are counted over a specific time interval
and the total for that period is saved as one record. It then starts the counting process over for
the next time interval and this process continues indefinitely. The place where this is stored is
called the "queue".
