E. CP320-TR1 (Optional)
Board Description
On the CP321 it is possible to utilize a transition module which provides optoisolated
RS485 functionality either half or full duplex where half duplex is the default.
Users who require a CP321 with an opto-isolated serial interface are supplied with a
customized CP321 on which the standard RJ45 connector is omitted (SER) and also
with this module which comes with a substitute RJ45 connector routed through optoiso-
lation circuitry on the module.
The module has been designed so that it does not increase the board width, which
remains unchanged at 4HP with the module in place.
