External or internal power supply of module Expansion port RS485/RS422 can
be made by wiring jumpers J2 and J3 on this module. If external power supply of the module
is required, jumpers J2 and J3 must be connected to pins 2 - 3. Internal power supply is
made by connecting pins 1 - 2 with jumpers J2 and J3.
