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 ports on the Connect IT provide console access to connected critical equipment through the

cellular network or a connected Ethernet LAN. You can connect up to four network devices to the

Connect IT serial ports. For pinout information, see

Serial port pinout and

You must use a cable with an RJ45 connector to connect to the Connect IT with an 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 ports are enabled by default. The network devices connected to the serial ports may be

accessed using Digi 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.

The RS232 standard requires support for baud rates up to 9600 baud on shielded multicore cable up

to 50 feet (15 meters) long. For the Connect IT 4, 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.
