Serial port 2
The serial port 2 is a general-purpose RS232 port with all control signals according to EIA-
561 that defines RS232 on a modular connector.
The signals are available on the RJ-45 connector located on the bottom side of the C350
pro unit.
Serial port 2 can also be allowed to hand over functionality to the internal GSM module to
work as GSM modem. Using this mode will effectively 'hand over' the GSM module inside
the C350 pro unit, so that it is exclusively controlled by any external device connected to
serial port 2 on the unit. Please consult the M2M Control IDE on-line help for further
information.
