Communication (RS-485 Port)
The RS-485 port provides a path for commands and information transmitted between
field panels or other BACnet devices. This port provides communications over an RS-
485 BACnet MS/TP
The RS-485 port provides half-duplex, asynchronous serial RS-485 communications
over shielded twisted pair cable. The communication terminations (+ –
network. The communication speed is set during startup using the
DIP switch.
) are shown
on the inside unit cover.
The PPM can reside on any BACnet building controller’s sub network. Refer to other
device manufacturer’s PICs and BIBBs to determine interoperability. Up to 32 MS/TP
devices can be supported on a BACnet/IP network*.
* The MS/TP PPM is an 1/8 load device.
