C. Optoisolation RS485 Module (Optional)
Board description
On the VMP2 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 VMP2 are supplied with a customized
VMP2 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.
