Multi Unit connection

RS485 Communication Port
The Multi Unit uses an RS485 port to perform the communication operations
with both the AFC1500 Servo (SAN) Controllers and the AFC User Console
(computer). Two RJ45 connectors are provided. Both connectors are internally
jumpered in parallel. Each port has two channels CH1 and CH2. CH1 is
dedicated to handle the communication with the User Console, that is to say,
all preset data upload and download, fastening results monitoring and
collection.
Channel CH2 is a high speed connection to all AFC1500 Servo Controllers. It
controls all required commands to perform the fastening cycle.
