Configuration is easy and trouble-free using T/Config, a Windows utility included free with your Remote Alarm Block. Using T/Config, a technician in the field can configure, provision, and turn up the unit, and also monitor alarm points, operate control relays, analyze communications traffic, and load firmware upgrades.

Firmware upgrades are free for the lifetime of the unit. Hardware upgrades are literally a snap. If the hardware module of your RAB ever needs to be replaced, you can remove the module without disconnecting a single wire.
