Installation and Startup  

You can use the I/O pin in conjunction with events reporting to configure the LX40 to send  

a report when the state of the monitored router changes, for example when a switch is  

opened or closed. For more information, refer to the ALEOS Software Configuration User  

Guide (Events Reporting chapter).  

Pulse Counter  

You can use the green wire to connect Pin 4 to a pulse counter. The digital pulse counter  

is not available in Standby mode.
