5-8 750/760 Feeder Management Relay GE Multilin5.2 S1 RELAY SETUP 5 SETPOINTS5b) PORT SETUPPATH: SETPOINTS Ö S1 RELAY SETUP ÖØ COMMUNICATIONS Ö PORT SETUPUp to 32 devices can be daisy-chained with one of them a computer or programmable controller. Either COM1 (the two wireRS485 or the four wire RS422 serial communication port) or COM2 (the two wire RS485 port) may be used. One relay canbe connected directly to a personal computer via the front panel RS232 port with a standard straight-through RS232 cable.• SLAVE ADDRESS: This setpoint selects the serial communications slave address of the relay. Both COM1 and COM2use this same address. The front panel RS232 port accepts any address for normal communications, but must be setto “1” when upgrading the relay firmware. Each relay on the same RS485/422 communications link must have aunique address.• COM1 and COM2 RS485/422 BAUD RATE: Selects the baud rate for the COM1 and COM2 RS485/RS422 communi-cation ports. All relays on the communication link, and the computer connecting them, must run at the same baud rate.The fastest response is obtained at 19200 baud. Slower baud rates should be used if noise becomes a problem. Thedata frame is fixed at 1 start, 8 data, and 1 stop bit.• COM1 and COM2 PARITY: Selects the parity for COM1 and COM2 communications ports.• COM1 and COM2 RS485/422 HARDWARE: Selects the COM1 and COM2 hardware configurations to be either two-wire RS485 or four-wire RS422 communications.• FRONT PANEL RS232 BAUD RATE and PARITY: These setpoints select the baud rate and parity for front panelRS232 serial communications port. When upgrading the relay firmware, the baud rate should be set to 9600.
