TSC3 NMEA Depth Input is different to echosounder output depth

Hi there, 


Hope someone can help.  I have recently purchased an echo sounder with its own acquisition software.  the software has the option to output NMEA.  I am able to receive data into the controller, however the depth being shown on the controller (continuous topo) is different to that being output by the 3rd party software.  I have checked the data being output using hyperterminal and the correct depth is being sent however there seems to be something amiss with the controller.  


I have noticed that when i vary the depth (transducer in test tank), the controller does not reflect the same level of change.

I have tried multiple baud rates (4800 to 38400) all with the same solution.


has anyone come across this before.


Many Thanks
