Connect equipment to the Connect IT serial ports

After your device is connected and powered up, you can connect equipment to the device using the
serial ports.
The serial port on the Connect IT Mini provide console access to connected critical equipment through
the cellular network, and optionally through a connected Ethernet LAN. Connect your network device
to the Connect IT serial port. For pinout information, see Serial connector pinout.
You must use a cable with an RJ45 connector to connect to the Connect IT Mini with a RJ45, DB9F or
DB9M connector, as determined by your device type, to terminate to your device. Consult the user
guide for the device you are connecting to the Connect IT to determine the connector type, cable type,
and pinout positions for your specific device.
The serial port is enabled by default. The network devices connected to the serial ports may be
accessed using Remote Manager, the local web user interface, TCP, telnet, or SSH connections. TCP,
telnet and SSH connections to serial ports are disabled by default and must be enabled by a device-
specific configuration.

Serial connector pinout

The RS232 standard requires support for baud rates up to 9600 baud on shielded multi-core cable up
to 50 feet (15 meters) long. For the Connect IT Mini the use of standard CAT 5 cables enables serial
communication at all baud rates up to 50 feet. CAT5 unshielded twisted pair cable lengths much
longer than 50 feet have been verified at 9600 baud but are non-standard and are not guaranteed.
The Digi Connect IT Mini RS232 serial port is DTE and has the following pin configuration.
