Optional settings
If your unit is the first or the last unit on the Modbus RTU network (see
Example 1
and
Example 2
), enable the NBT resistor via 3SModbus or Sensistant. If your device
is not an end device, leave the NBT disabled (default Modbus setting).

ATTENTION
If an AC power supply is used with any of the units on a Modbus network, the
GND terminal should NOT BE CONNECTED to other units on the network or
via the CNVT-USB-RS485 converter. This may cause permanent damage to the
communication semiconductors and / or the computer!
