DIY Logitech 4000 SC1 mod (Serial Port)

This is an update to my previously-built Logitech 4000 SC1 modification in 2011. Note that the modification was originally designed to work with Parallel ports. Since such ports are now obsolete, changes to the circuitry have been implemented to allow the modified camera to be connected to newer laptops via USB ports (by using a USB-to-Serial Port adapter).

  1. Hi Anthony,

    thank you very much for your interesting article.

    I have an EQ-5, steppers and astroberry ( with an attached OnStep Controller (

    Yesterday evening I stumbled upon you article, because I wanted to test my C600 Webcam (housing: with phd2.
    Since I had problems using this cam due to the limited exposure time I saw, that the actual version of phd is able to:

    * autostack frames
    * automatically create and use a darks library for the cam
    * automatically create and use a bad pixel library for the cam

    So there is no need to alter the electronic circuits any more ;-) Im using the raspberry pi, and with Kstars and INDI I am configuring the cam as a V4L linux device. And them in PHD am using the INDI driver. Works fine. Field test is coming.
