INTERFACE OVERVIEW INTERFACE OVERVIEW This manual describes how to use the remote command functionality and lists the command details. The Overview chapter describes how to configure the GDS-200/300 USB remote control interface.
PAGE 6
GDS-200 & GDS-300 Programming Manual Interface Configuration The GDS-200/300 uses the USB device port for remote control. When using the remote control function, the GDS-200/300 acts as a virtual COM port (VCP). Note New drivers can be downloaded from the GW Instek website, www.gwinstek.com.
PAGE 7
INTERFACE OVERVIEW Remote Control Function Check Functionality check Invoke a terminal application such as Realterm. In the terminal program, set the COM port, baud rate, stop bit, data bit and parity to match the settings for the virtual COM port of the DSO. To check the COM settings of the DSO in Windows, see the Windows Device Manager. For example, in WinXP go to the Control panel → System → Hardware tab.

GDS-200 & GDS-300 Programming Manual Using Realterm to Establish a Remote Connection Background Realterm is a terminal program that can be used to communicate with a device attached to the serial port of a PC or via an emulated serial port via USB. The following instructions apply to version 2.0.0.70. Even though Realterm is used as an example to establish a remote connection, any terminal program can be used that has similar functionality. Note Realterm can be downloaded on Sourceforge.
PAGE 9
INTERFACE OVERVIEW The baud rate, stop bit and parity settings can be viewed by right-clicking connected device and selecting the Properties option. 4. Start Realterm on the PC as an administrator. Click: Start menu>All Programs>RealTerm>realterm Tip: to run as an administrator, you can right click the Realterm icon in the Windows Start menu and select the Run as Administrator option.

GDS-200 & GDS-300 Programming Manual 5. After Realterm has started, click on the Port tab. Enter the Baud, Parity, Data bits, Stop bits and Port number configuration for the connection. The Hardware Flow Control and Software Flow Control options can be left at the default settings. Press Open to connect to the GDS-200/300.
PAGE 11
INTERFACE OVERVIEW 6. Click on the Send tab. In the EOL configuration, check on the +CR and +LF check boxes. Enter the query: *idn? Click on Send ASCII. 7. The terminal display will return the following: GW, GDS-310, XXXXXXX,VX.XX (manufacturer, model, serial number, version) 8. If Realterm fails to connect to the unit, please check all the cables and settings and try again.
