3.3.1 Communication Converters (OpenBAS-ACC-RS485, OpenBAS-ACC-
RS232)
By default, the COM1 communication terminal is configured as RS-485 through factory-
installed modules. It can be changed to RS-232 or optically isolated RS-485 by installing the
OpenBAS-ACC-RS232 or OpenBAS-ACC-RS485 converters.
Attention: This job must be performed only by a certified technician as dangerous
voltages might be present inside of the enclosure.
Always disconnect the power before installing accessories.
