The OR-485 is an externally powered, isolated converter or repeater with diagnostic leds. There are two input ports which can be jumper selected for either RS232 for connection to a PC as a converter, or RS485 for bus repeater mode. The  isolated,half-duplex RS485 output port has two separate connectors to make dividing the network easy during troubleshooting.  The diagnostic LEDS show common wiring mistakes such as shorts & open circuits. All protocols such as Bacnet, Modbus or generic RS485 protocols are supported since the device is a hardware only repeater, however some of the diagnostics such as bad CRC and Modbus error reporting are available only with Modbus at 19.2k or 9600 baud.
