Hello, everyone! This post describes how to configure the ATN910C's ALMI / O interface to an external sensor case.
【Problem Description】
ALMI/O interface on the system control board of ATN910C is used to connect to external sensor such as mainframe door sensor or temperature sensor.
How to configure ALMI/O interface to connect to external sensor?
Handling Process
None
Root Cause
None
Solution
The following procedure explain how to configure ALMI/O interface to connect to external sensor such as cabinet door sensor:
1. Connect RJ45 network cable to ALMI/O interface and the other ends will be connected to the external cabinet door sensor.
2. By default, ATN910C will not detect the status of the digital input signal of the external sensor, we must configure the normal status of the digital input signal.
3. Run display io-alarm to check the status of the io alarm before configure the alarm name and status of the alarm; the Default-status and Alarm-name is "NA".

ATN910C's io-alarm status:
Index Status Default-status Alarm-name Alarm-status
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
1 open NA NA Normal
2 open NA NA Normal
3 open NA NA Normal
4. Configure the Alarm-name as "mainfail" and default-status to "open". Run the display io-alarm again, Default-status and Alarm-name is updated and the current Alarm-status is "Normal".

ATN910C's io-alarm status:
Index Status Default-status Alarm-name Alarm-status
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
1 open open mainsfail Normal
2 open NA NA Normal
3 open NA NA Normal
5. Verify the configuration to check if is correct by loop wire of the network cable.

ATN910C's io-alarm status:
Index Status Default-status Alarm-name Alarm-status
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
1 close open mainsfail Abnormal
2 open NA NA Normal
3 open NA NA Normal
Above is an example of configuration steps and testing result for one external sensor.
1. Connect RJ45 network cable to ALMI/O interface and the other ends will be connected to the external cabinet door sensor.
2. By default, ATN910C will not detect the status of the digital input signal of the external sensor, we must configure the normal status of the digital input signal.
3. Run display io-alarm to check the status of the io alarm before configure the alarm name and status of the alarm; the Default-status and Alarm-name is "NA".

1 open NA NA Normal
2 open NA NA Normal
3 open NA NA Normal
4. Configure the Alarm-name as "mainfail" and default-status to "open". Run the display io-alarm again, Default-status and Alarm-name is updated and the current Alarm-status is "Normal".
