Connecting a PC to UCM/Eth2

[Vangelis]

Running Comfort II Ultra with a UCM/Eth2

Needing to upgrade the firmware of both the Comfort and KP06 (see other thread) I finally got around to connecting the PC to Comfort (or as the case turned out...I tried )

Looking at the instructions there are three ways to connect..

1) PC to Hub with Comfort to Hub (all straight thru CAT5)
2) PC to Comfort (straight thru CAT5)
3) PC to Comfort (x-over CAT5)

Assumption was that the Comfort (like a PC) would pick up a DHCP lease once connected, however the instructions mentioned that Comfort was preconfigured with an IP in the range of 10.0.0.51-10.0.0.60.

This was a pain as my Home Hub runs the 192.168.x.x range.

Scenario 1

Loading up ComFigurator, the instructions stated to set an IP (in the range of your choice) under Settings -> UCM Connection and then via DS manager, let the PC \'Discover\' the IP address of Comfort.

It\'s this last bit I have trouble understanding as DS Manager is running on a PC (that already has an IP address from my Hub) and it fails, stating no connection to UCM

Scenario 2

Now I set my PC with an IP in the 10.0.0.x range, in the hope DS manager will see Comfort with it\'s pre-defined IP (10.0.0.51-60)
This also fails and it cannot discover the UCM

Scenario 3

This will be tried later as my x-over cable is at work.

All the LEDs look good and the Green RDY light is on. The RED LED on the ETH2 module is on and blinks occasionally and the RED & Green LEDS for comms back to the Comfort CPU are blinking furiously

Soooo I guess I am missing something here, and doing something wrong. The instructions are a little mis-leading as what IP address Comfort has and how to set it up.

The problem is in order to go through the usual check and potential firmware upgrade I need the UCM/Eth2 to get an IP and I do not have the serial interface...

So my questions are....

1) Do I use a straight thru or x-over CAT5 cable?
2) Do I plug Comfort into my Hub and will it get a DHCP lease? If not, how do I change it\'s pre-defined IP when DS Manager cannot see it..?
3)Do I plug Comfort into my PC and set a local IP range?? If so what settings do I use?
4) Have I missed a guide on the forums as to how to connect to Comfort for the first time?

Firstly dsmanager should be able to see the ucm irrespective of it\'s IP address as it is discovering devices on the network based on their MAC address. So first thing is to discover why dsmanager isnt finding it; try switching off your firewall for a few minutes to see if that then allows the discovery to work.

Once you can see the ucm in dsmanager then you set the IP address and or whether it should use dhcp or static IP via right clicking that discovered device.

Only once setup via dsmanager do you then if set the IP address to match in comfigurator.

Personally I would give the ucm a static address rather than a dynamic one.

Hope this helps you get a bit further.

Thanks Julian,

Just seen the comment about the different IP subnetting not being an issue in http://www.comfortforums.com/forum92/3398.html

So would you connect your PC direct to Comfort or via my Home Hub.

When I look at the Home Hub details, I cannot even see that the Ethernet port (from Comfort) is connected, but suspect that is because it doesn\'t yet have IP?

Do you use straight or x-over cables?

I suggest you connect Comfort and PC to your Home Hub (not sure what that is but assume it is a router or switch) with a straight cable

If you cannot see Comfort in DS Manager it means that it is physically not connected, or the UCM/Ethernet is not powered on. Check that there are leds lighted on the UCM annd the ETH submodule. When you plug in the lan cable the leds on the ETH port should show some activity

The UCM/ETH will always have an IP address even if unconfigred, so that cannot be a problem

Thanks...

The HomeHub is an ADSL Router - I might power cycle that (as Julian suggested).

My understanding, moving forward, is do NOT configure an IP address under UCM in Comfigurator, but use DS Manager to \'discover\' it first.

As a side note - I have not changed anything with the UCM ID as its the only UCM connected, so assuming out of the box this is default to 1

All the lights on the UCM/Eth2 are on and flickering. Have seen post whereby you need to power cycle the UCM/Eth2 (as opposed to a Comfort reset) in order to kick things back into life.

It does not matter which is done first, DS manager or setting IP address in Comfigurator

The correct way  to look at it is the IP address /Port in Comfigurator Options > Settings should be the same IP address/Port assigned to the UCM/ETH DS Manager.

Correct

All the lights on the UCM/Eth2 are on and flickering. Have seen post whereby you need to power cycle the UCM/Eth2 (as opposed to a Comfort reset) in order to kick things back into life.

Not sure if that is relevant but try that and see if you can discover the IP address
also check the lan cable

Did some more testing last night but still with no luck, I am still unable to see the IP/MAC address of the UCM/ETH2 in the DS Manager.

Looking at the UCM/ETH2 module, all the lights look ok...

D10/D9 are flickering, RDY light is green, No error lights, D101 is on

However when I press SW101 on the little module card the lights on the ETH socket alternate?? Any ideas?? Is this Duplex??

 

[Vangelis]

One thing I did notice is that the Green LED on the ETH Socket flashes about once a second, and I would expect that to be solid??

If I press SW101, then the Yellow LED opposite the Green on the ETH Socket lights up??

When I look at the status lights on the switch, where the PC and Comfort are plugged into, when I issue the \'Refresh\' cmd on DS manager I can see traffic going out - but DS manager never see\'s the IP/MAC come back.

I have used numerous (working) cables - suspicion lies with the LEDs on the ETH socket however as they don;t look right??

 

[Vangelis]

btw - I reseated the small ETH module and thats why it\'s not sitting on the PCB rider posts properly

Suspect this will require warranty testing, however the distributer doesn\'t distribute anymore  Will I be ok to send this back to Cytech for checking if required?

Maybe just timing of the shot but interesting that the LED on the Ethernet port is showing no activity.
