For correct RS485 wiring: Follow the guidelines for RS485 wiring.
If the wiring shown in the table below is incorrect, please let us know.
There is no general consensus in the industry about the usage of A and B for the RS485 polarity, so it may be counterintuitive and opposite of what you might expect for some devices.

Device	a-TroniX Controller model OM1	a-TroniX Controller model IG8	RS485-USB converter	RS485-Ethernet converter
D1/+	RS485 A	RS485_POS	RS485 A	TX+
D0/-	RS485 B	RS485_NEG	RS485 B	TX-
0V	RS GND	GND	Not available	G

You MUST give each device on the RS485 bus a unique address. Check the manual of the device on how to do this.
Use lower addresses first (1, 2, ...) because the a-TroniX Controller will find them faster!
For each device, it is generally recommended to stick with the factory default baud rate, parity, and stop bits. The a-TroniX Controller will scan on those first.
