How to Configure Ethernet Settings
The device’s Ethernet port is equipped with Auto-MDX, which allows it to automatically detect and adapt
to being connected using either straight-through or crossover Ethernet cables.
When the device is connected to the host via Ethernet, on power-up the device attempts to contact a
DHCP server to acquire a dynamic IP address. If the device is configured to use a static IP address, it
uses its preconfigured IP address instead.
If the device fails to obtain an IP address from a DHCP server, the device assigns itself a link-local IP
address using APIPA (also known as auto-IP). To find the link-local address, you can use a utility
program such as
finder.exe
(supplied by Texas Instruments).
The default port for the host to communicate with the device via the network is
port 26
.
On some devices, network functionality and the following network-related keypad commands are only
