3.3.1 Communication Converters (OpenBAS-ACC-RS485, OpenBAS-ACC-
RS232)
By default, the field bus ports (labeled COM1, COM2 and COM3) are configured as RS-485
through factory-installed modules. They can be changed to RS-232 or optically isolated RS-
485 by installing the OpenBAS-ACC-RS232 or OpenBAS-ACC-RS485 converters.
The communication converters OpenBAS-ACC-RS485 and OpenBAS-ACC-RS232 attach to
the connections labeled P1, P2, and P3 in Figure 5 below. Figure 5 also shows the relationship
between the 3 converters and the field bus connections (labeled COM1, COM2, and COM3).
P1 controls COM1, P2 controls COM2, and P3 controls COM3.
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.
