Abstract
An automated test system for testing devices being manufactured comprises an infrared communications link for free space communications between a host and a device under test. The communications link is asymmetric and instructions from the host are acknowledged by the device. The instructions cause the device to operate, and the output of the device is monitored, logged, and compared to acceptance criteria. The host can then generate calibration messages to the device, to change the device operating characteristics as appropriate. The communications link uses an unmodulated data stream together with asynchronous handshaking and a robust checksum algorithm to ensure accurate communication.
