MS-2000 control using NI’s LabVIEW 8.6 and the Serial Port

Home » Support » Downloads » MS-2000 control using NI's LabVIEW 8.6 and the Serial Port

ASI has recently begun experiencing USB driver installation issues with the Microsoft™ Windows® XP operating system. Until resolved, ASI offers this solution.

The serial port remains a viable, recommended alternative to USB for controlling the MS-2000, therefore, ASI is providing this Serial Pack which includes instructions on setting up and using the serial port to control MS-2000 controllers with LabVIEW™ 8.6.

In situations where USB communication is mandatory, ASI will provide a USB-to-Serial Adapter, or you may acquire your own (for example, the Keyspan™ USA-19HS).

Installation Contents

This package contains National Instruments LabVIEW™ 8.6 source code to support MS-2000 control over the Serial Port interface.

Self-contained One-VI Solutions

These three VI’s use only LabVIEW™ built-in functions as sub-VI’s

• SerialMoveXY.vi – Connects, moves X and Y axes, waits for completion of move, disconnects
• SerialMoveZ.vi – Connects, moves Z axis, waits for completion of move, disconnects
• SerialWhere.vi – Connects, issues WHERE command to input axis, returns axis position in 10ths of micron, disconnects

*Note: Connecting and disconnecting is fast enough so that these VI’s are recommended for normal applications

Example Interactive Applications

• SerialComplexInteractive.vi – Emulates HyperTerminal®
• SerialSimpleInteractive.vi – Sends hand-typed commands, ignores replies

Subordinate VI Files

• SerialConnect.vi – opens serial port
• SerialDisconnect.vi- closes serial port
• WriteCmd.vi – concatenates CR LF to a command, transmits
• SerialWaitForStatusN.vi – sends STATUS commands up to a max number of tries (default=400), returns Success = TRUE if it receives ‘N’ (i.e., not busy)
