Wiring Diagram of SeTAQ AD-S321：
If the RS485 signal wires are too long, or there are several AD-Smodules are connected on the same bus, these modules may not be found due tolack of driving capacity. Then please connect a module’s RA with +5V through a 1kΩ pull-up resistor R1, and connect the module’s RB with GND through a 1kΩ pull-down resister R2. Note that if there are severalAD-S modules are connected on the same bus, you can only add a pull-up resistor R1 and a pull-down resistor R2 to the AD-S module which is the farthest from PCconverter or PLC. If this does not solve the problem, you can also add a pull-up resistor R3 and a pull-down resistor R4 to the other end of RS485 wires.
