4.2 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
enabled when the device’s USB cable is not connected.
To show the MAC address of the device, press keypad buttons Left function key 6 2 2 Right
function key.
To show the current IP address of the device, press keypad buttons Left function key, 4 7 2 Right

To show the device’s network configuration information such as mode (DHCP/Static), IP address,
subnet mask, and default gateway, press keypad buttons Left function key 2 4 8 Right function key.
To change the device’s network configuration, such as mode (DHCP/Static), IP address, subnet mask,
and default gateway, press keypad buttons Left function key 2 4 7 Right function key, then follow
