|
Test Equipment:
|
This test equipment designed for a customer to do automatic simultaneous design verification testing of 12 CD ROM and/or cassette mechanisms.
Test Equipment Technology:
|
 |
- The tester is rack mounted and is controlled by a PC running LABVIEW software.
- 12 Microchip micro controllers communicate with one Siemens 80C166 microcontroller. The Siemens in turn controls the communications with the PC.
- Software was written in both C and assembly languages.
- A hand held controller can plug into the front panel and allow the user to manually control the tester without a PC attached.
