5-28 C70 CAPACITOR BANK PROTECTION AND CONTROL SYSTEM – INSTRUCTION MANUALPRODUCT SETUP CHAPTER 5: SETTINGS5 5.3.4.2 Serial portsSETTINGS PRODUCT SETUP COMMUNICATIONS SERIAL PORTSRS232 BAUD RATE, RS485 COM2 BAUD RATE, and PARITY — The C70 is equipped with two independent serial communicationports. The faceplate RS232 port is intended for local use and has two options for baud rate. The rear COM2 port is RS485and has settings for baud rate and parity. It is important that these parameters agree with the settings used on thecomputer or other equipment that is connected to these ports. Any of these ports can be connected to a computerrunning the EnerVista software. This software can download and upload setting files, view measured parameters, andupgrade the relay firmware. A maximum of 32 relays can be daisy-chained and connected to a DCS, PLC, or computerusing the RS485 ports. If IEC 60870-103 is chosen as the protocol, valid baud rates are 9600 and 19200 bit/s, and validparity is Even.RS485 COM2 RESPONSE MIN TIME — This setting specifies the minimum time before the rear RS485 port transmits afterreceiving data from a host. This feature allows operation with hosts that hold the RS485 transmitter active for some timeafter each transmission.
