EXPANSION PORT MOUNTING

Interface behaviour of module Expansion port RS485/RS422 can be made by wiring
jumpers J4, J5 and J6 on this module. If RS485 is required, jumpers J4 and J5 must be
connected and jumper J6 disconnected. If RS422 is required, jumpers J4 and J5 must be
disconnected and jumper J6 connected.
Jumper placement can be seen in the picture below (module Expansion port
RS485/RS422 from TOP layer). We recommend that internal power supply is only chosen
in the event that it is not possible to ensure external power supply. If internal power supply
is chosen, converter RS485/RS422 is not galvanic separated.
