DS2405(3) One-Wire File System DS2405(3)NAMEDS2405 - 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 deter‐
mine the actual logic level at the switch, refer to the sensed prop‐
erty.
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 PROPERTIESALARMS
None implemented.
DESCRIPTIONDS2405
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.
