C.2 RJ-45 Connector
Lantronix servers are RS-423 compliant, and are thus limited by the
equipment at the remote end of the serial line. If the Server is connected to an
RS-232 device, it is subject to RS-232 limits.
RS-232 lines are limited to 15m (50 ft.) in length at 9600 baud, and to 2m (6 ft.)
at 115.2K baud, although they will generally work at longer lengths.
