The N60 is equipped with two independent serial communication ports. The faceplate RS232 port is intended for local use
and is fixed at 19200 baud and no parity. The rear COM2 port is RS485. The RS485 port has settings for baud rate and par-
ity. It is important that these parameters agree with the settings used on the computer or other equipment that is connected
to these ports. Any of these ports can be connected to a computer running EnerVista UR Setup. This software can down-
load 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 DCS, PLC, or computer using the RS485 ports.
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 which hold the RS485 transmitter active for some time after each transmission.
NOTE
c) ETHERNET NETWORK TOPOLOGY
The N60 has three Ethernet ports. Each Ethernet port must belong to a different network or subnetwork. Configure the IP
address and subnet to ensure that each port meets this requirement. Two subnets are different when the bitwise AND oper-
ation performed between their respective IP address and mask produces a different result. Communication becomes
unpredictable when more than one port is configured to the same subnet.
