5-12 B90 Low Impedance Bus Differential System GE Multilin5.2 PRODUCT SETUP 5 SETTINGS55.2.5 COMMUNICATIONSa) MAIN MENUPATH: SETTINGS PRODUCT SETUP COMMUNICATIONSb) SERIAL PORTSPATH: SETTINGS PRODUCT SETUP COMMUNICATIONS SERIAL PORTSThe B90 is equipped with up to three independent serial communication ports. The faceplate RS232 port is intended forlocal use and is fixed at 19200 baud and no parity. The rear COM1 port type is selected when ordering: either an Ethernetor RS485 port. The rear COM2 port is RS485. The RS485 ports have settings for baud rate and parity. It is important thatthese parameters agree with the settings used on the computer or other equipment that is connected to these ports. Any ofthese ports may be connected to a computer running EnerVista UR Setup. This software can download and upload settingfiles, view measured parameters, and upgrade the relay firmware. A maximum of 32 relays can be daisy-chained and con-nected to a DCS, PLC or PC using the RS485 ports.
