The B90 is equipped with up to 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
parity. It is important that these parameters agree with the settings used on the computer or other equipment that is con-
nected to these ports. Any of these ports cam 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 DCS, PLC, or PC 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
When using more than one Ethernet port, configure each to belong to a different network or subnet using the IP addresses
and mask.
Example 1
IP1/Mask1: 10.1.1.2/255.255.255.0 (where LAN 1 is 10.1.1.x/255.255.255.0)
IP2/Mask2: 10.2.1.2/255.255.255.0 (where LAN2 is 10.2.1.x/255.255.255.0)
