External or internal power supply of expansion port RS485 can be made by wiring
jumpers J2 and J3 on this module. If external power supply of the module is required, jumper
J2 must be connected to pins 2 - 3 and jumper J3 must be disconnection. Internal power
supply is made by connecting jumper J2 to pins 1 - 2 and connecting jumper J3. Jumpers
placement can be seen in the picture below (expansion port RS485 from TOP side). We
recommend that internal power supply be only used in the event where it is not possible to
ensure an external power supply. If internal power supply is chosen, converter RS485G is
not galvanic separated.
