Relay-Based Multiplexer Assembly Guide and Binary Input Exploration

This guide details the assembly process of a Relay-Based Multiplexer using key components including EMF dampeners, LED indicators, and switch headers. Step-by-step instructions cover connecting boards, switches, and battery harnesses to effectively construct the MUX main tree. Additionally, activities are provided to engage users in understanding binary input selection, converting binary to decimal. Ideal for electronics enthusiasts looking to learn about multiplexing, relay operations, and binary systems.

  3. Populate Sensor-MUX Qty4 • R3 TBD • R4 TBD • R5 TBD • R6 TBD • R7 TBD • R8 TBD

  4. Populate MUX main tree Qty3 • SW1 3 pin header • SW2 3 pin header

  5. Jumper Cables

  6. Assemble the boards-Parts • 3 SPST switch harnesses • 1-9v battery harness • 10-3 wire connectors • 4 Sensor boards • 3 standard boards

  7. Step one • Connect switch to topmost board SW1 • Connect SW1 to SW2 on next board down • Continue on remaining 2 boards

  8. Step 2 • Connect switch to topmost board SW1 • Connect SW1 to SW2 on next board down • Connect first row of boards to second row as shown
