Connecting
Cables
Dual Ethernet and RS485 ports enable
point-to-point networking demos on a
single TWR-P1025 module. Any Ethernet
cable can be connected between the
Ethernet ports and the ports will auto-
configure for proper communication. Auto-
configure also enables a direct connection
from either Ethernet port to a host
computer Ethernet port. All TWR-P1025
headers have pin 1 marked with a white
dot printed on the board and increasing
pin numbers proceeding top to bottom,
right to left from pin 1 while looking into
the header pins.
For cable connections on other interfaces,
refer to the user manual.
Controlling
the Board
Upon power-up, you can also hit any key
on a connected serial terminal to get to
the u-boot prompt, otherwise the board
will boot to the Freescale Linux OS.
You can also log in to the module via
the OpenWRT interface by opening your
browser to 192.168.1.1 (you will need to
connect your PC LAN port to the module’s
Eth0 port and reconfigure your PC IP
address to 198.168.1.54). The OpenWRT
interface will allow for easy configuration
of the module’s network settings. Use the
following information to log in:
Login: root
Password: root
Standard u-boot and Linux commands are
supported.
