Connect the RS485 slave interface of the second AMC

If a second device receives its power supply from a first,
then please connect the power lines (pin 1 and pin 2) as
well as the data lines (pin 3 and pin 6).
If the devices have their own power supplies then the
cable shielding should be grounded at one end only. The
loose end should be insulated to prevent any inadvertent
contact.
If one device passes power through to another, then the
cable shielding should be grounded at both ends.
