4 Channel Hub
Hobby Boards 4 Channel Hub
The 4-channel hub has:
- RJ45 connections
- Passthru connector for the main branch
- 4 branches
- electrically isolated
- short tolerant
- individually switchable (on/off)
- LED to indicate branch on
- Power from external source or 1-wire cable (and power injector)
Unlike the DS2409-based Microlan hubs, devices on the branches appear on the main list.
Example with a temperature sensor on the branch:
DS2409

EF.1234123434The controls for the 2-channel Hub are very simple:
To read or write status:
EF.1234323424/hub/branch.0To see if there is an electrical short on the branch, read
EF.1234323424/hub/branch.1
EF.1234323424/hub/branch.2
EF.1234323424/hub/branch.3
EF.1234323424/hub/branch.ALL # a comma separated list of branch status
EF.1234323424/hub/branch.BYTE # binary number of the status (15=all on, 2=only branch.1 on)
EF.1234323424/hub/short.0
EF.1234323424/hub/short.1
EF.1234323424/hub/short.2
EF.1234323424/hub/short.3
EF.1234323424/hub/short.ALL # a comma separated list of branch shorts
EF.1234323424/hub/short.BYTE
