Hi,
Let's resolve the issue. So, that scales software does not work correctly when using NSPK virtual port. Usually the problem is related to timing issues. Could you please play a bit with "Network Latency Compensation" option.
If does not help, let's see it in details.
We need investigate serial traffic to know exactly why it appears and to find the proper solution.
Usually we use portmon program to monitor serial traffic.
Please download it from here:
http://download.sysinternals.com/Files/PortMon.zip
Please use the following portmon setting:
Edit -> Max Output Bytes -> 1024
Options -> Show Time [x]
Options -> Show Hex [x]
Options -> Clock Time [ ]
Experiment 1
============
Remote PC (physical COM port)
1) Launch portmon
2) Configure portmon to capture data from physical COM port: Capture -> Ports -> ...
3) Launch communications program and work with your device for some time. Then close communications program.
4) Save captured data to file: File -> Save As -> remote1.log
Experiment 2
============
Remote PC (physical COM port)
1) Launch NSPK and share physical COM port
2) Launch portmon
3) Configure portmon to capture data from physical COM port: Capture -> Ports -> ...
Local PC (virtual COM port)
1) Launch NSPK and create virtual COM port connector (redirected to physical COM port of the remote PC)
2) Launch portmon
3) Configure portmon to capture data from virtual COM port: Capture -> Ports -> ...
4) Launch communications program and work with your device for some time. Then close communications program.
5) Save captured data to file: File -> Save As -> local2.log
Remote PC (physical COM port)
4) Save captured data to file: File -> Save As -> remote2.log
Please send us there 3 log files: remote1.log, local2.log and remote2.log
