Installing Software for Developers

Thorlabs provides instrument drivers (API) for developers who want to integrate the

LC1-USB in their own software. The instrument drivers provided here are based on

National Instruments™ VISA technology. Thorlabs provides a driver for National

Instruments™ LabWindows/CVI™ and LabVIEW™ programming environments as

well as for Microsoft™ and Borland™ compilers. All of these drivers need VISA to be

installed. From the website of National Instruments™ (

www.ni.com/visa

) you can

download two different versions of VISA (a fully featured version “NI-VISA” and a

runtime only version “VISA-Runtime engine”). The minimum version to run the

examples provided on the CD is the “VISA-Runtime engine” which is included on the

CD. However you may find it very helpful to have the full version “NI-VISA” installed

while you are developing your software. Please make sure to follow the license

conditions of National Instruments™ when you use the full version of “NI-VISA”.

A note on USB

USB devices are recognized by the host through their identifiers VID (

vendor

identifier

) and PID (

product identifier

). These IDs are 16bit unsigned integer values.

Thorlabs’ PID is 1313

HEX

.The factory setting for the LC1-USB is 0010

HEX

and this is

the PID used by the Jungo™–USB drivers and spectra. For use with VISA the PID

for the LC1-USB has to be changed to 0110

HEX

. There is a small tool on the CD

called ‘LC1-USB PID Changer Tool’ that is built for exactly this purpose. Since this

tool can access the LC1-USB regardless of its current PID both USB drivers Jungo™

and VISA have to be installed. Please install this tool and change the PID of the LC1-

USB to 0110

HEX

for VISA if you intend to use the instrument drivers provided.

By clicking on ‘Install VISA drivers’ of the CDs Autorun Menu you will install the

instrument drivers together with a sample application on your PC. The drivers will be

installed below C:\VXIPNP\WinNT\Thorlabs_LC1_Drv. Make sure that you have

installed VISA before attempting to run the sample applications.
