Digital Output Communication Buffers
Remote digital communication is provided by Digital Output Communications
Buffers (DOC) via a two wire RS485 serial channel using the COMLI protocol.
Each Digital Output Communications Buffer can accept one analog input and
produces one analog output. Each buffer block also holds two parameters, Mode
and Identity. Each block may be given a twenty letter identification name by
configuring the parameter Identity.
