DS2405(3)

NAME
DS2405 - Addressable Switch

SYNOPSIS
1-wire network branch controller.

05 [.]XXXXXXXXXXXX[XX][/[ PIO | sensed | ]]

FAMILY CODE

05

SPECIAL PROPERTIES

  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
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.

STANDARD PROPERTIES

ALARMS
None implemented.

DESCRIPTION

  DS2405
The 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.
