USB LOI Override Function

The USB LOI override function allows dedicated access to RS-485 multi-drop bus when the USB is connected. This allows a Technician maintenance access to the connected RS-485 devises without removing or changing field wiring. The USB connection also allows technicians to perform maintenance tasks using modern laptops which lack physical serial (RS-232) Ports.

RS485 and RS232 Output

Allows flexibility in SCADA Installations where both RS-485 and RS-232 instruments need to be interfaced without adding extra converters or serial splitters.
