Your Module

I/O messages are sent to (consumed) and received from (produced) the
ArmorPOINT I/O modules. These messages are mapped into the processor’s
memory. This ArmorPOINT I/O input/output module produces 6 or 10
bytes of input data (scanner Rx - status). It consumes 2 or 4 bytes of I/O data
(scanner Tx). See the 1738 ArmorPOINT adapter User Manual, publication
