Chapter 5 Configure Ports 67
Recommended sequence for configuring port settings
If using the Basic and Advanced configuration settings to configure serial
ports, the sequence is:
1. In the Web interface for the the Digi Passport unit, go to
Serial Port > Configuration.
2. Before connecting any serial devices to the Digi Passport unit,
configure the Automatic Detection feature. On the Configuration page,
click Port automatic detection configuration. Create a port automatic
detection list, which is a set of common serial port characteristics used
to determine which kind of device is attached to the Digi Passport unit,
such as baud rate, data, parity, stop bits, and a string sent to the device
to detect its operating system and host name. The port automatic
detection list is used as probe criteria when Automatic Device
Recognition is activated and the serial ports are tested. For more
information on Automatic Detection settings, see "Configure Automatic
Detection" on page 77. Here is a typical example of probe criteria.
3. Click Save & apply.
4. Enable Automatic Detection for all ports: In the serial ports view
(Serial Port > Configuration), click All to select all ports. Change the
Automatic Detection setting from Off to Active.
5. Click Save & apply.
6. As needed, change configuration settings for individual ports, using
either Basic configuration or Advanced configuration settings.
Basic configuration settings are described on page 68. Advanced
configuration settings are described on page 92.
