5.3.1 Register – Detcon Type

The Detcon Type is a unique identifier of the type of device and associated register map. A controller can

therefore perform a search and determine what Detcon devices are present on a Modbus™ system. A

controller can look for this value when search Modbus™ addresses 161 to 192 to find the Modbus™ address

of the RXT-300 that it is attached to.

5.3.2 Register – Alarm Outputs

There are four registers that give the status of the four open collector Alarm Outputs. A value of 0 denotes the

Alarm Output is not grounded and a value of 1 or non-zero value denotes the Alarm Output is grounded. The

default value for all Alarm Outputs upon power up or reset is 0.
