Protek 608 RS-232 cable teardown

Protek 608 RS-232 cable
This post is a continuation of the Protek 608 DMM software project.

Here’s some photos of the Protek 608 RS-232 cable teardown:

Bill of materials

You know a teardown is serious when a BOM is produced! 😛 This may be overkill, but I have plans in future to develop my own transceiver hardware that instead of using RS-232 to connect to a PC, it will use a cheap WiFi module or Bluetooth module.

    Very Good brake down
    can you call me ay (918) 629-9297 I was the director of electronic at ORU University
    we use the protek 608 to Demonstrate to the students i have a ? i think you can answer
