1. DS2406 datasheet for more information about the 1 Wire slave chip The switch controller interprets the PIO A input as negative logic Doing so insures the switch is turned off when the DS2406 is in the reset state The family code of the DS2406 is 12h Since the family code alone doesn t uniquely identify a 1 Wire Mains Switch device the host system must associate the full 8 byte ROM code with the device 8 User Manual 1 Wire Mains Switch The following diagram shows how to The following diagram shows how to turn on the switch turn off the switch 55h match ROM 55h match ROM User Manual 9 1 Wire Mains Switch 5 Software Support Q WS Software package ows v1 0 0 and later includes program owswitch This program enables you to fully control the 1 Wire Mains Switch Example invocations of the program owswitch i2cdev dev i2c 0 ds2482 24 ch 7 id 12 974696 on This command turns on the switch The device is supposed to be connected to channel 7 of the DS2482 800 chip gt owswitch exe lu pr id 12 974696 off This command probes the 1 Wire Mains Switch on all USB to 1 Wire adapters If found the program turns off the switch owfs It s assumed you re using the filesystem client of the owfs package In the examples it s suppose you ve specified mnt onewire as the mount directory for the 1 Wire file system Since owfs inverts all accesses to PIO channels the default negative logic become2. 1 Wire Mains Switch User Manual July 2013 1 Wire Mains Switch Table of Contents 1 Features 3 2 Technical Specifications 3 3 Safety Precautions 4 4 1 Wire Mains Switch 5 Board Overview 5 1 Wire Terminal Block Connector K2 5 1 Wire RJ45 Connectors K3 K4 6 1 Wire Slave Power Selection J1 6 Mains Connector K1 7 1 Wire Connectivity 7 Communications Protocol 8 5 Software Support 10 ows 10 owfs 10 6 Application Notes 11 7 Disclaimer 11 8 Contact Information 11 Revision History Date Authors Description 2013 03 14 Peter S heeren Initial release 2013 04 28 Peter S heeren Added extra safety precaution Added section about software support Second release 2013 07 21 Peter S heeren Added section about owfs software support Third release 2 User Manual 1 Wire Mains Switch 1 Features Available in 230 V and 120 V versions Reinforced safety insulation between mains voltage and one wire bus Low power consumption typically less than 400 mW Three connection points for 1 Wire cabling and wiring 2 Technical Specifications Weight 47 g with fuse Dimensions 96 mm x 54 mm x 18 mm W x D x H User Manual 3 1 Wire Mains Switch 3 Safety Precautions SAFETY PRECAUTIONS DO NOT TOUCH THE DEVICE WHEN IT IS CONNECTED TO MAINS VOLTAGE DO NOT MOUNT OR PLACE THE DEVICE CLOSE TO INFLAMMABLE MATERIALS USE A FUSE OF 50 mA ONLY THE LOAD CIRCUIT MUST BE PROTEC
