Key Operating Modes The simulator board operates in two distinct modes via DIP switch configuration: Mode Operation Use Case Single Packet Transmits one data packet determined by digital input Trigger testing, specific protocol validation Continuous Stream Continuous packet transmission with identical data Long-term analysis, protocol decoder testing Protocol Selection and Control Protocol selection utilises a dedicated DIP switch array allowing instant switching between supported communication standards. The board features convenient test points and standard logic analyser probe compatibility for seamless integration into existing test setups. Compatibility Note: Designed primarily for Zeroplus logic analysers but compatible with most logic analysis systems supporting standard voltage thresholds (TTL/CMOS). Physical Specifications Measuring 7.0cm (W) × 9.7cm (D) × 2.5cm (H), the board maintains a compact footprint suitable for benchtop testing environments. The PCB includes multiple ground connections and signal routing optimised for minimal noise and crosstalk during protocol generation. // Example connection setup Logic Analyser CH0-7 → Protocol Output Pins Ground References → Board GND pins Power Supply → 5V DC input Protocol Select → DIP switch array Applications in Development Essential for embedded system validation, the simulator board enables testing of communication protocols before deploying to live systems. Engineers use it for protocol decoder validation, timing analysis verification, and logic analyser trigger configuration testing. Development Advantage: Eliminates the need for complex hardware setups when testing protocol analysis capabilities, reducing development time and increasing testing reliability.
