SCSITerm 08-15
This project is a design of an active SCSI terminator for DB-25 ports.
Pictures
The picture below shows Revision3 of the board.
Parts list
- 1 DB-25 male (solder cup)
- 1 Voltage regulator SOT-223 LD1117 SC-R (or similar)
- 18 Resistors 110R 0805
- 1 Resistor 680R 0805 (R19, optional)
- 1 LED 0805 (optional)
- 3 Capacitors 10uF 0805
- 1 Resistor 220R 0805 (R21)
- 1 Resistor 330R 0805 (R20)
- 1 Resistor 2k 0805 (C3, instead of a previously planned capacitor for accurate 2.85V)
Building and installation notes
Soldering should be straightforward for the SMD components and the DB-25 connector. Please don't forget the resistors on the underside of the PCB.
The PCB was designed with typical DB-25 shells in mind to be used as enclosure. Nevertheless, a custom case design for 3D printing is part of the repository. Just print the design twice and fasten it using M2.5 x 10 cylindrical screws and matching nuts.
