2) Ensure the following file exists and its contents are not blank.

To do this:

1. Navigate to C:\ProgramData\DSI\DACSS\
   Note: ProgramData is hidden
2. Open the user.settings file in Notepad and see if it contains any contents. 
3. If it is blank, copy the following into the file:

</ArrayOfEntry>

4. Select File | Save.
5. Then close the user.settings file and open Ponemah.

 3) Ensure the computer IP address and the CLC IP address are properly configured.

 If there is a IP address conflict, the Ponemah debug log will have the following error:

This can happen, for example, in the following scenario :

• The CLC is configured in DHCP mode. When it boots up, it gets the following address from the DHCP server (router) : 192.168.1.101.
• The PC is (incorrectly) configured with the following static address : 192.168.1.101 (note it's the same as the CLC).
  The PC will detect the conflict and move to a different IP address, like 169.254.107.127.
• When Ponemah starts, the error "Digital Telemetry Files Not Found" is displayed.

Ensure the network settings of all system components (PC, CLC/MX2, E2S-1/APR-2, cameras) are configured correctly and consistently.
