 Serial mode allows normal serial operation.
 Input mode allows input of GPIO signals. Alarms can be issued when GPIO
pins change state. Input mode is used in conjunction with alarms to trigger
emails or SNMP traps when a particular signal change is detected (see
"Alarms" on page 39).
 Output mode allows output of GPIO signals. This mode can be used to toggle
the output of GPIO signals between high and low.
The configuration and current state of GPIO pins can be easily viewed, through the Web
user interface or by issuing commands from the command line.
DHCP Server
The Digi Connect WAN device is running a DHCP server. The DHCP server is enabled by
default but can be disabled in the setup wizard. Configure the setup device to obtain IP
adresses automatically. This eliminates subnet errors.
