Configure Digi devices
Serial Bridge profile
The Serial Bridge profile configures one side of a serial bridge. A serial bridge connects
two serial devices over the network, each of which uses a Digi device, as if they were
connected with a serial cable. The serial devices “think” they are communicating with
each other across a serial cable using serial communication techniques. There is no need
to reconfigure the server or the serial device. Neither is aware of the intervening network.
Serial bridging is also known as serial tunneling.
This profile configures each side of the bridge separately. Repeat the configuration for the
second Digi device of the bridge, specifying the IP address of the first Digi device.
Local Configuration profile
The Local Configuration profile allows for connecting standard terminals or terminal
emulation programs to the serial port in order to use the serial port as a console to access
the command line interface. Profile settings enable and disable access to the command
line.
Modem Emulation profile
The Modem Emulation profile allows a Digi device to sends and receive modem
responses to the serial device over the Ethernet instead of PSTN (Public Switched
Telephone Network). This profile allows maintaining the current software application but
using it over a less-expensive Ethernet network.
The commands that can be issued in a modem-emulation configuration are described in
the Digi Connect Family Command Reference.
