RS-485 EXPANSION
The HazPAC R9-8.4 provides a RS-485 Expansion Port. The port is available on the left side of
the enclosure via the RJ-45 connector labeled “RS-485 OUT,” as well as via a 4 pin terminal
block.
The HazPAC R9-8.4 includes a RS-485 expansion connector on the left side of the unit that is
internally connected to the same pins on the screw terminals, also on the left side of the unit.
This offers two convenient options for adding additional expansion modules.
The RJ45 port on the left side of the HazPAC R9-8.4 is a RS-485 Expansion Port (labeled
“RS-485 OUT”) and is NOT an Ethernet port. Damage to Ethernet networking equipment
can result if connected to the RS-485 RJ45 connector.
