Factory Reset
Should it be necessary to reset the ETH8020 to its shipped condition then the end two contacts of the
row of 5 holes near the large chip on the side nearest the Ethernet connection must be shorted together
at board power up. Keep the pins shorted until the green power LED starts to flash, this will take up to
5 seconds. The green LED will flash as the settings are reset, please wait until the LED finishes
flashing and do not remove power during this period.
Firmware Updates
The firmware is fully updateable by re-flashing the board using our custom windows program. The
updates currently available are:
V2 - 07/02/2014 - DNS and Gateway string lengths corrected in http config page, new latching
function added to config and board name now appears correctly on NBNS (WINS) meaning routers
display board name.
Using the Ethernet module update:
First you need to connect to the board, the program will scan the local network and provide any boards
in a list that it can see.
Next you will need to specify what port the board is located on, this will be 17494 unless you have
changed it in the settings.
If there is a TCP/IP password the program will require it to be entered by clicking the password button.
