Table 7-2, ENV Connector and Pin Descriptions
Steps to configure DM3X Transponder to monitor I/O device.
1. Set atiMgmtSysIoSelect appropriately (SNMP or Web) for device to monitor.
OID 1.3.6.1.4.1.926.1.3.2.8.1.0
1 = Generic
2 = LAP Only
3 = Heater/Cool Control Only (Heater Mat)
4 = DC Emergency Generator Only
5 = Heater/ LAP
6 = DC Gen LAP
The device can be selected through the Web page by navigating to ‘Advanced Configuration’,
‘I/O – Environment’ and selecting from the pull-down list
2. Configure alarms (Generic Only – See below section for details)
3. Monitor appropriate SNMP parameters (See each section below for details)
7.6.3 Configuring I/O Port Connections
Alpha has created logic for control and reporting of specific devices or combination of devices. The Alpha proprietary
SNMP MIB atiMgmtSysIoSelect, 1.3.6.1.4.1.926.1.3.2.8.1.0 must be set appropriately before the device status will
be correctly reported. The monitored device can also be set through the transponder’s “Advanced Configuration -
I/O” Web page pull-down. The status of the generic I/O Pins can still be monitored and alarmed via the SCTE-HMS
discretePropertyTable even when specific devices have been selected.
