This USB device will show up on your system as a serial device and allow for a fully isolated serial communication with CyberPower UPS devices that have support for RMCARD202/RMCARD205 interface.
It was inspired with Jeff Mayes Serial Interface and wouldn't be possible without his extensive research.
To connect to the device, access serial device using 2400,8,N,1 (2,400 baud rate, 8 data bits, no parity, 1 stop bit) parameters. Protocol is described here.
Tested devices:
- OR500LCDRM1U
- OR700LCDRM1U
