We create applications that communicate with electronic devices through RS232 comm port / USB port. Signal could send to device for command execution. Data would receive and kept in database for reporting purposes. For example, we communicate with ESD (Electrostatic Discharge) Tester and retrieve for electrostatic test result for the production employees. Another example, we instruct the Electric Safety Compliance Analyzers to run several steps of testing, wait and resume test, and for same final purposes, record for test result for reporting purposes.
