# [SYNOPSIS](#SYNOPSIS)

1-wire network branch controller.

# [FAMILY CODE](#FAMILY_CODE)

# [SPECIAL PROPERTIES](#SPECIAL_PROPERTIES)

## [PIO](#PIO)

*read-write, yes-no*  
State of the open-drain output ( *PIO* ) pin. 0 = non-conducting (off), 1 = conducting (on).  
Writing zero will turn off the switch, non-zero will turn on the switch. Reading the *PIO* state will return the switch setting. To determine the actual logic level at the switch, refer to the *sensed* property.

## [sensed](#sensed)

*read-only, yes-no*  
Logic level at the *PIO* pin. 0 = ground. 1 = high (~2.4V - 5V ). Really makes sense only if the *PIO* state is set to zero (off), else will read zero.

## [DS2405](#DS2405)

The [**DS2405 (3)**](/man/os/owfs/DS2405.3) allows control of other devices, like LEDs and relays. It is an early design and has been superceeded by the **DS2406** and **DS2408** or even **DS2450** that have more PIO pins, and do not employ an arcane use the the alarm state to signal PIO status.
