Configure serial interfaces
Digi routers support a variety of serial interfaces, either inbuilt or as optional add-on modules. Each
asynchronous serial (ASY) port may be configured to operate at different speed, data format etc.
These parameters may be changed using the web interface or from the command line using AT
commands and S registers.

1. Go to Configuration > Network > Interfaces > Serial.
2. A list of supported serial interfaces displays below the Serial link. Click one of the interfaces to
configure basic serial configuration.
Note On models fitted with W-WAN modules, one of the interfaces and its associated web page
are dedicated to the W-WAN module. The title will reflect this. Similarly, on models fitted with
an analogue modem, one of the interfaces will be entitled PSTN port.
Enable this serial interface
When disabled, this is the only item that appears in the section. Enabling this setting displays
additional configuration parameters.
Description
A description for the interface. For example, if the serial interface is connected to a card
payment device, the description could read Till 1 or similar appropriate text.
Baud Rate
The required baud rate for the associated serial port.
Data Bits / Parity
The required data format for the interface. 8 data bits, no parity is a very common
configuration.
