1 Wire serial

Scenario 1

Identified the COM port number of your device, I cannot find the COM port number inside the software. What I need?

For example: I've installed the software on Windows XP. When TEMPer1W v1.0.4 starts up it offers me a selection of COM ports to connect to - 0 to 15. However the USB9097 is reported to be on port 25. How do I resolve this?

Solution: Modify the COM port number of the device recognizes. (For example: win7 OS)

1.  Open “Computer Management”


2.  Find “Device Manager”->”Ports(COM &LPT)”->”USB-SERIAL CH340(COM25)”


3.  “USB-SERIAL CH340(COM25)”->”Properties” open


4.  Click “Port settings”, “Advanced”;

5.  Select “COM port Number”, Click “OK”;


6.  Unplug the device, then plug the device. Check whether the port is changed.
