Optoisolation RS485 Module (Optional)

Board description

On the VMP1 it is possible to utilize a transition module which provides optoisolated

RS485 functionality (half and full duplex).

Users who require an optoisolated version of the VMP1 are supplied with a customized

VMP1 on which the standard RJ45 connector is omitted and also with this module which

comes with a substitute RJ45 connector routed through optoisolation circuitry on the

module.

The module has been designed so that it does not increase the board width, which

remains unchanged at 4TE with the module in place.
