DS2409 microhub

DS2409 Microhub


DS2409-based

  • Two addressable branches: main and aux
  • Supported in OWFS

    • Unlimited branching (but there may be electrical problems with cumulative resistance).
    • OwfsAlgorithm
  • Commercial devices based on Simon Atkin's design

  • Excellent analysis and sample dephi program from T.K. Boyd.

    • Kits and Completed projects
    • Full example of use

 

Caveates

Unfortunately, the DS2409 is "Not Recommended for new designs" and is apparently being phased out.

The branching within OWFS directories is unique, but creates some difficulties -- selecting and searching subbranches requires extra addressing information for every step. Also, it's harder to find devices.

For just the electrical reliability of multiple 1-wire lines consider:

  • LINK-HUB (IButtonLink)
  • HA7Net (EDS)
  • OW-SERVER-ENET (EDS)
  • OW-SERVER-ENET-2 (EDS)
  • 4 Channel Hub (Hobby Boards)

 

To have control over the individual branches:

  • OW-SERVER-ENET-2
  • 4 Channel Hub
