The GPI-1501 is a 2RU Densité card that provides 20 dedicated GPI (General Purpose Interface) inputs plus eight terminals that can be individually configured as either a GPI input or GPI output. When paired with an iControl Application Server, the GPI-1501 provides alarm aggregation from older devices that do not offer Ethernet port connectivity. The Application Server can report alarm status information to operators via iControl or SNMP. It can also trigger external events, such as selecting an alternate source.

In iControl, you can configure GPI outputs to respond to alarms triggered on another card on the network.
