GENERAL
This document describes about Models ALR111 and ALR121 Serial Communication Modules (for FIO) that a field control station (FCS) uses to perform serial communication with subsystems such as FA-M3. These serial communication modules can be mounted on field control units (AFV30, AFV40, AFV10, and AFF50), ESB bus node unit (ANB10), optical ESB bus node unit (ANB11), and ER bus node unit (ANR10).
