Configuring the USB Interface

PC side connector Type A, hostUSB connection

GDS-1000 sideconnector

Type B, slave

Speed 1.1/2.0 (full speed)

Panel operation 1. Connect the USB cable tothe USB slave port on therear.

2. When the PC asks for the USB driver, selectdso_cdc_1000.inf which is downloadable fromthe GW website, www.gwinstek.com.tw, GDS-1000 product corner.

3. On the PC, activate a terminal application suchas MTTTY (Multi-Threaded TTY). To check theCOM port No., see the Device Manager in thePC. For WindowsXP, select Control panel SystemHardware tab.

4. Run this query command via the terminalapplication.*idn?This command should return the manufacturer,model number, serial number, and firmware

version in the following format.GW, GDS-1022, 000000001, V1.00

5. Configuring the command interface iscompleted. Refer to the other chapters for moredetails.
