Page 4: Introduction
Sensors can be polled on a regular basis (from 1 to 99 minutes), or manually interrogated. In a typical application, 1WSwitch is connected to a serial port on a PC. Serial interface software is then used to gather the data received from 1WSwitch and process it. - Page 5 • Manual Poll of sensor readings. While 1WSwitch is normally used for continuous (from 1 to 99 minute intervals) polling of sensor readings, it can also be used manually to take sensor readings on command from the serial interface.

1WIO relay units from the 12V output of 1WSwitch, the transformer needs to supply at least 350mA (250mA for 1WIO and 100mA for 1WSwitch) per 1WIO relay unit, up to a maximum of 800mA, or 2 1WIO relay units. Beyond that, supplemental powering will need to be provided for the off-board units. -
Page 7: Using 1Wswitch
Note: an ERA command is not required every time that an INI command is issued. It should only be required for first time use. If you believe that 1WSwitch has not found all 1-Wire devices, re-issue the INI command. Now program the configuration by using the command. - Page 8 – the state of all switch sensors is normally preserved through a power cycle. Use the command for all DS2406’s (or DS2407) and command for DS2405’s. If there are no apparent errors, you are ready to use 1WSwitch. Enjoy! 1WSwitch User Guide Version 1.02 Page 8 of 28...

Page 12: Using The Set Command
Enter the time in decimal minutes. Use the command to adjust only this parameter. Serial # Display Set this to On if you want 1WSwitch to display the 1-wire ID of all sensors. Use the command to adjust only this parameter. Time Display Set this to On if you want 1WSwitch to display the voltage as measured at connector J2 pin 3. -
Page 13: The Dis Display Output
OnBoard ADC Display Set this to On if you want 1WSwitch to display the output from the on- board Analog to Digital Converter connected to pin 3 of J2 and referenced to ground on pin 4 of J2. Use the command to adjust only this parameter. -
Page 14: Using The Eep And Mem Commands
After entering the command, 1WSwitch will display the contents of memory. Use the “;” key to advance to the next memory location, and use the “/” key to go to the previous memory location. -
Page 15: Missing Sensor Display
1WSwitch continuously polls for the presence of all sensors that have been registered via the command, in other words, for sensors that are known to 1WSwitch. If any of the sensors are detected as missing, the following display will result: >MON 09:52:34... -
Page 16: Options
Polling of sensors is done sequentially and very fast (milliseconds per sensor). The more sensors that are equipped, however, the more time it will take for 1WSwitch to recognize a missing or re-added sensor. 6.6. Options 6.6.1. On Board ADC Display (DAD) The DAD (Display A to D) option is to enable or disable the on-chip voltage sensor (Analog to Digital Converter, or ADC). -

MD2088 8 LED Ouput 6.7. DS2408 Based Relay and LED Usage 1WSwitch software has the ability to actuate relay modules based on the DS2408 port expander chip from Dallas/Maxim. One such module is the Midon Design 1WIO. The 1WSwitch supports up to 40 1WIO relay modules (MD2083) and the command input then actuates those relays (numbered from 01 to 80). -
