For high data rate Ethernet logging using TCP/IP, disable Windows Delayed Ack Algorithm (DAA)
for complete data logging. If you do not disable DAA, there will be data gaps due to the Windows
Ethernet buffer.
If done incorrectly, changing the Windows Registry may impair the operation of the
computer. Editing the Windows Registry is for advanced Microsoft Windows users
only.NovAtel Inc. is not able to provide any technical support for any actions taken
