You need a terminal application to be able to use the service port commands of the HMDW110 series transmitter. You can download the PuTTY terminal application from http://www.vaisala.com/en/search/download or use a terminal application of your choice.
Before starting a terminal session, you must set the following parameters:
- Serial line settings. The default serial line settings of a HMDW110 series transmitter are 19200 N 8
- 19200 bits per second
- No parity
- Eight data bits
- One stop bit
Number of the virtual COM port that has been created for your cable by the Vaisala USB driver.
You can check which port the USB cable is using with the Vaisala USB Device Finder application that has been installed in the Windows Start menu. You can also access the USB finder directly from the Vaisala-supplied PuTTY application by selecting USB Finder... on the Serial & USB tab.
