Serial
Configuration – Network > Interfaces > Serial
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.
The Configuration – Network > Interfaces > Serial menu item opens out when clicked,
to show the list of supported serial interfaces.
Note:
On models fitted with W-WAN modules, one of the interfaces (and its associated web page)
will be 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.
The Configuration – Network > Interfaces > Serial menu has the following sub-menu
options:
• Serial Port n
• Sync Rate Adaption
• Command Mappings
• Protocol Bindings
• TRANSIP Serial Ports
• RealPort
• Multitx
