GND	4-		-5	NC

Protocol

Modbus RTU (Wikipedia). Serial baudrate defaults to 115200/8n1 and Modbus slave address defaults to 1. Both can be changed in the main menu at any time. There is also an option using WiFi instead of USB/Serial, which uses a fixed Baudrate of 115200/8n1.

Also see the RDTech_DPS_series page. External sources exist which combine communication to DPS as well as UM as well as RD devices in a single project. Protocols may be similar enough to make a common driver desirable.
