PRODUCT SETUP
5.3.5.2 Serial ports
5
The T60 is equipped with up to two independent serial communication ports. The faceplate RS232 port is for local use and
is fixed at 19200 baud and no parity. The rear COM2 port is used for either RS485 or RRTD communications.

It is important that the baud rate and parity settings agree with the settings used on the computer or other equipment that
is connected to these ports.
The RS485 port can be connected to a computer running EnerVista UR Setup. This software can download and upload
setting files, view measured parameters, and upgrade the relay firmware. A maximum of 32 relays can be daisy-chained
and connected to a distributed control system (DCS), power line carrier (PLC), or a computer using the RS485 ports.
The baud rate for standard RS485 communications can be selected as 300, 1200, 2400, 4800, 9600, 14400, 19200, 28800,
33600, 38400, 57600, or 115200 bps.
For the RS485 port, the minimum time before the port transmits after receiving data from a host can be set. This feature
allows operation with hosts that hold the RS485 transmitter active for some time after each transmission.
