ET 238 - Device Peripherals
Credits: 3
Description
Covers the key components and sub-assemblies used in slot machines and other self-service devices such as Kiosks, and ATMs. Instruction includes topics such as opto-couplers, thyristors, bill acceptors, and interface standards, microprocessors/controllers, power supplies, switches, and displays.
Student Learning Outcomes
- Explain and analyze embedded microprocessor systems and memory technologies, including ROM, PROM, EPROM, EEPROM, and RAM.
- Identify, analyze, and interpret electronic circuits used in self-service devices such as slot machines and ATMs, and evaluate the theory of operation of a typical device.
- Explain and compare the modes of operation of the devices covered in the student’s concentration.
- Analyze and evaluate device sub-assemblies and components—such as pseudo-random number generators (PRNGs), coin and bill acceptors, stepper motors, printers, and card readers—to determine functionality and performance.
- Describe and distinguish the external features of systems such as slot machines, ATMs, and kiosks.
- Apply and evaluate systematic troubleshooting procedures for diagnosing faults in these systems.
- Apply and justify proper ESD control measures and safety precautions.
- Describe and interpret the operation of peripheral devices within these systems.
