Register Locations
Each Enabled Analog Expander channel will store data in a Register held by the Protege Integrated System
Controller. Each Register is assigned an address, and the register address range used by each Analog Expander
channel depends on the AExxx address of the module. Each Analog Expander Module uses 4 Register
Addresses, with Register addresses starting from 000. This means that Analog Expander Channels will link to
registers as shown in the table below.
