TH2523 Series Operation Manual

Ver1.2

When user is using USBTMC interface, labview software can be used to access the

instrument.

6.4

USBCDC Virtual Serial Port

When “USBCDC” is selected, the USB interface can be configured as a virtual serial port

(VCom)

Connect PC and TH2523 to the USB interface through a USB cable.

Methods of installing USBCDC driver are the same with that of installing USBTMC driver.
When the installation of driver is finished, user can see “usb VCom port” in the PC device

manager, as is shown in figure 6-8.

Figure 6-8 VCom Display of PC Device Manager

Now, usb VCom port acts as a serial port. When PC has no serial port, the communication

software based on this serial port can be used as USB virtual serial port.
