Connecting a PC to UCM/Eth2

May also be worth trying to discover the UCM via DSExplorer (you can get from Tibbo website) rather than DSManager.

Hi Julian,

Correct regarding the ETH Port light - the Yellow LED never lights unless I press SW101 and then the green LED goes out.

After a module reset the Green LED comes on and pulses once a second, which doesn\'t look correct - especially if this is the \'link\' light...


Also the intensity of the LED changes when I plug in the CAT5 (that has a switch on the other end)

The meaning of the leds from the UCM manual are

Ethernet LED Indicators
D101 - Link Status LED (Red) - This turns on when ‘active’ Ethernet cable is
plugged into the Ethernet port and blinks whenever an Ethernet packet is
received.


RJ45 connectors LEDs (Green and Amber) - dual-function Ethernet status
LEDs. The Green LED should be on when connection is established, and
blinking while connection is being established. The Amber LED should be off
in normal operation and on as error indication.

D101 should be always on
The RJ45 led should be steady green. Blinking means it is trying to establish a connection

SW101 is for programming mode and should not be used normally

I suggest you use DS Explorer and try to upgrade the firmware on the EM500
download cytech3_13.bin from https://www.cytech.biz/eth02_firmware.ht...ory_id=101

Note that this is NOT the UCM firmware on the base board
The instructions for DS Explorer upgrade if ETH02 firmware is in the UCM Manual

Vangelis, did you get it working?

Superb (NOT)  Now I think I have fubar\'d the ETH2 Module by following the instructions...

Fired up DS Explorer and it discovered my UCM (only the hammer and not the Blue barrel) so there was only one line visable, with an IP address in the same subnet as my hub (weird)

Downloaded the firmware .bin file and uploaded it via DS Explorer - progress bars stayed blank, so I waited...and waited (instruction state it should only take seconds)

So I hit cancel (think this is what broke things), I the refreshed on DS Explorer and got the same \'hammer\' identifyer but now with a 1.0.0.1 IP address (again, weird)

Tried uploading again and still no progress bars, so hit cancel. Now when I hit Refresh on DS Explorer I don;t see the UCM module and on the RJ45 Connector both the Green and Yellow LEDs are flickering very fast

Unplugged the module from the power and plugged back in again - still flashing RJ45 Connectror LEDs - hence suspician is it is now fubarred  - Not happy

Thoughts?

Ok..progress..after reading the manual (doh) I found you could reset the ETH module by holding down SW101 for 7 secs on powerup (Now I know what that buttons for )

This brought the module back into life - DS Explorer refresh again, and can see hammer again. Perform the upload and I can now see progress - yay!

Once complete I refresh again and now see two lines (hammer and barrel). DS manager now sees the IP and I can set it - wahoo

Now and reading in Config to the PC from Comfort

Thanks good. You\'re off now...

Upgrading ethernet firmware by DS Explorer is normally prevented by firewalls liek Zone alarm
If you turn off the firewall, it will go ahead

Hello,
I\'m currently experiencing the same connection issue with my ETH02 module.
I can get the module worked in the following states  (neither with DS explorer neither with DS Manager):- RJ45 green LED blinking about twice a second (normal operation ?)- RJ45 green LED frozen when entering in programing mode (SW01 pushed down for 7 sec at start)- RJ45 green and amber LEDs blinking alternately very fast (overfilling of buffer ?)
Anyway, for none of the above states, I\'ve succeeded in connecting to ETH02 from the computer. I tried direct connection between PC and ETH02 as well as through a switch. Also, I\'ve tested with static IP on the computer but of course I have no idea of what is the exact ETH02 IP. From my understanding, this is not a needed information to detect with DS explorer and DS Manager? Of course, I\'ve disabled also the computer firewall.
Nothing detected by DS explorer and DS manager. So, its not possible to upload the firmware to latest revision (3.13) as I cannot see it in DS Explorer. 
As additionnal information, the ETH02 module worked previously and was configured with a static IP. For some reasons, I\'ve changed the subnet IP range (192.168.1.x to 192.168.0.x). I have also some mapping between MAC and IP address in the router. But as I tested the direct connection between PC and ETH02 module, I don\'t think it might be related to my issue.
Any suggestions to make it worked ?
Thanks.

Perhaps you can set your PC IP address to the old subnet 192.168.1.x fixed IP address and try pining or connecting to the ETH03 at the old IP address?

The ETH02 possibly may be faulty. The Tibbo modules tend to heat up. It may be better to buy a new ETH03 submdoule. Your UCM baseboard should still be usable, and can be upgraded to the latest UCM firmware
