To avoid confusion, the RS and RS signals of WMT700 are named as follows:
• Inverting: –
• Non-inverting: +According to the EIA-485 standard, the lines are named as follows:
• Inverting: – <=> A
• Non-inverting: + <=> B
The AB naming used by some manufacturers is in conflict with the standard. To ensure proper operation, verify the polarity of the signals when using the device on the bus with signals named as AB. Opposite polarity causes data inversion on the bus, but it does not damage the device.
