To see Comfort Server Manager, Go to Options > Settings > UCM Connection> select UCM Interface = Network (Local). Click on Comfort Server Manager
The main cause of Comfort Server Manager not being able to see the ETH03 IP address is due to the presence of another network Adaptor in the PC, eg a Virtiual Machne. Comfort Server Manager sends the request on the other network adaptor and does not find the ETH03Go to Control PanelNetwork and InternetNetwork Connections to see the network adaptors.

If the firmware is corrupted and the ETH03 IP address cannot be seen in Comfort Server Manager, reset the ETH03 module to default and DHCP mode
- Press and hold SW2 switch.
- Press SW1 RESET once.
- The Green D2 LED on the ETH03 will turn off for about 5 seconds and then turn back on.
- Maintain the press-and-hold of the SW2 switch until another cycle of turning off and turning on of the D2 LED on the ETH03 module. This will take around 10 more seconds.
- Run the CS Manager software to discover the ETH03 module.
If a DHCP server is not on the network, the ETH03 will have an IP address of 192.168.0.109
ETH03 LED Indicators
D2 STATUS LED (Green) - Steady on to indicate ETH03 application is running correctly.
D3 PWR (Red) - Steady on to indicate power to the ETH03 module.
RJ45 connector LEDs (Green and Amber) - These are dual-function Ethernet status
LEDs. Both LEDs are off when there is no connection. The Green LED should be on when it is connected to the LAN. Amber LED blinks slowly when the connection is idle and flashing fast when there is data transfer.
Other causes of ETH03 not seen in CS Manager

NOTE THAT COMFORT SERVER MANAGER CAN ONLY WORK ON THE SAME NETWORK AS THE UCM/ETH03, NOT FROM INTERNET
[/color]
If the UCM/ETH03 cannot be seen in Comfort Server Manager after doing a Reset to Default as described in the previous post, it could be due to the router blocking UDP port 30303 which is used for discovery.
Try using another Router or connect the UCM/EH03 directly to the PC LAN port as a test
Connect the ETH03 ethernet port directly to the computer to verify that the ETH03 IP address can be discovered. A LAN cross cable may be needed, although modern computers may not need cross cables.
You can set the computer IP address using a Fixed IP address as there will be no DHCP
If the PCs IP address is not in the same subnet as the ETH03 (default IP address 192.168.0.109) then the IP address will appear in RED
If the ETH03 can be discovered when it is connected direct to the PC but not when it is connected to the LAN, there may be a problem with the router or the network
Try disabling the Firewall on the router and PC
Also connect the UCM/ETH03 direct to the router bypassing other switches and Hubs in the network
Use PING to the ETH03 IP address
Go to Start, type CMD in the text box
In the DOS Box type Ping 10.0.0.55 for example
If there is a reply that means the ETH03 is working.
You can use Comfigurator with the ETH03
Discovery of ETH03 in Comfort Server Manager - Technical Information
Comfort Server Manager uses UDP Port 30303 to discover the ETH03 IP address
ETH03 will reply to the query also using UDP Port 30303
The screenshot below is from Wireshark, which is a useful free tool for network troubleshooting
Set \"Promiscuous mode\" on Wireshark
Apply filter UDP==30303 to the captured packets
In line 110, Comfort Server Manager running on the PC (192.168.1.2) sends a broadcast on UDP port 30303 to destination port 30303
In Line 111, the ETH03 replies on UDP port 30303 to destination port 30303 of the querying IP address. Its IP address (source ) is 192.168.1.204
Hence if UDP port 30303 is blocked on the router or switch or PC, there will be no reply from the ETH03 and the discovery will not work
Note that Comfort Server Manager will send the discovery broadcast only
Once (it may repeat the request if there is no reply). If there is no reply after repeating, it will not broadcast again, unless the
Refresh button is pressed on Comfort Server Manager.
Try disabling all Firewalls which may be blocking the UDP port
If the ETH03 IP address appears and disappears repeatedly, this is due to a network error, which is probabaly caused by a loop in one of the switches or network devices. Note that this condition was actually seen at a site. This problem is not caused the ETH03 or Comfort Server Manager
If the UCM/ETH03 IP address cannot be seen in Comfort Server Manager due to one of the causes above, try connecting the LAN Cable from UCM/ETH03 direct to the PC Lan port.
Set a Static IP address for the PC, since there is no DHCP server in this configuration.
For instructions for different versions of Windows, see
http://www.howtogeek.com/howto/19249/how...windows-7/
Once the PC has a static IP address, run CS Manager again. You should be able to see the UCM/ETH03 IP address. If it still cannot be seen, disable any firewalls on the PC temporarily.
If the ETH03 IP address can be seen, change the IP address to a valid fixed IP address on the network. At the same time, upgrade the ETH03 firmware if necessary
Connect the PC and UCM/ETH03 back to the router or switch as before
You can now use the IP address and port that was set by CS Manager to communicate with the UCM/ETH03
For those running Windows 10 on Mac using Parallels, and cannot see ETH03 in Comfort Server Manager;Try changing the network mode from Shared to Bridged. This allows the IP addresss to be in the same network as the home network so CS Manager can talk to ETH03.

Alternately if you still camnot see the ETH0 IP address in Comfort Server Manager, use the router to find the IP address of ETH03 In the router page you should be able to see the IP Addresses or Devices which are connected by LAN to the router. Remove the cable from ETH03, check the IP Addresses, then plug in the cable to ETH03 and check devices again and see if a new IP address has been added
