3.1 Files Required for WinMux2k Driver Installation
3.2 Installing the WinMux2k Driver
Before starting the installation make sure that all files are located in the same folder as the wmuxinst.exe:
• winmux2k.inf
• winmux2k.sys
• wmuxprop.dll
1 Start the program wmuxinst.exe.
2 Ensure that the module is connected to a serial port and turn the module power on.
3 Press the “Scan” button of the application. All Siemens modules found will be listed in a box. If no modem has
been installed yet, the virtual ports can be selected. If it is properly installed, the virtual ports are shown. If at
least one modem is found, the “Install” button becomes active. Pressing this button will cause the selected
modules to be installed.
4 Use the Device Manager to check that the installation was successful.
The virtual ports are available without reboot. The driver instances are visible in the device manager class “Multi-
port Serial Adapters”. If you wish to uninstall the driver see
Section 3.3 .
When migrating from TC45 or XC18 to another module type or vice versa we recommend to uninstall the driver
and reinstall it with the new module. This way, you can take advantage of the module specific power down
sequence determined during the driver installation and executed each time after closing the last virtual port (see
Section 2.8.2 and Section 4.2 ).
Although it is not recommended, it is possible to modify the driver’s factory defaults by editing, prior to the driver
installation, the parameters contained in the winmux2k.inf file. This approach can be used, for example, if you
want to use another default baud rate or if you want to replace the string AT+CFUN=0 with one of the CYCLIC
SLEEP mode settings supported by your module, such as AT+CFUN=5 or 6 or 7 or 8 or 9. See also
Section 4.2 .
Note: During the installation a pop-up dialog with "Digital Signature Not Found" will appear. Please ignore this
message and continue the installation process. The reason for the message is that the driver has not been reg-
istered with Microsoft, but its correct functionality is ensured.
