Connecting Multiple R364 Boards
Multiple R364 modules can be controlled from a single computer port. Each module is assigned a unique address character, and the RS485 bus ports are wired in parallel. Unless you have a RS485 I/O card in your computer you will need the RS485 to RS232 Converter Card (ACC-01, sold separately) to control the multiple R364 boards using your PC serial port. (See Section 11 in the manual)
NOTE: RS485 to RS232 Converter Card is not necessary for single board connections. A single R364 board can connect using the onboard RS232 or RS485 connectors.
