14 PM45 and PM45c Accessory User Guide
RS-485 Isolated, Full Duplex (reconfiguration required)
Note: The RS-485 circuit is available as a spare part.
Connector Configuration (RS-485 on “uart2”)
Note: The increased use of LAN networks has made the RS-485 interface somewhat
obsolete, because RS-485 requires a special communication protocol and a
dedicated wiring system limited to 1,200 m(4000ft). We only recommend RS-485 for
existing application and advise the customer to consider a LAN network solution for
new applications.
