• Type: manual
• File size: 369.9 KB

Manual Overview

The Sencore Chipper Check interface box is designed for alignments and EEPROM testing with a computer. It features two separate power supplies: the Input Side Supply and the Output Side Switching Supply, both providing approximately 5 volts. The Input Side Supply uses two parallel 150-ohm resistors and a 5.1 V zener diode, with C28908 filtering the voltage. A reading of 5 V across C28908 indicates a functional supply. The Output Side Switching Supply uses IC U28904 as a drive oscillator, with Q28902 amplifying the drive to produce alternating current in the transformer, resulting in a rectified and filtered 4.8 volts output.

The interface box includes 10 signal lines between the input and output connectors, with separate data return and input paths, as well as clock lines for signal transport. Opto-coupler ICs and a power supply transformer isolate the input and output sides. Troubleshooting involves checking these components and ensuring proper voltage references: S1 ground for the input side and S ground for the output side. The power adapter provides approximately 12 VDC, with an illuminated LED indicating power status.

Quick Issues Covered

• Diagnose power-up failures with Chipper Check interface box.
• Troubleshoot EEPROM testing issues using block diagram.
• Trace circuit paths with simplified schematics for signal lines.
