Software / Control
The 1-Wire interface is controlled by standard commands for the DS2408 device.

Control via 1-Wire Controller / 1-Wire Gateway
The 1-Wire interface of the 8-fold digital output 8 is controlled by standard commands for the device DS2408. The
8-way switching module can be easily controlled via a 1-wire controller / 1-wire gateway. Two commands are
available for this purpose. Please refer below for the two commands.
10.1
Switching an output relay
To switch a relay output, use the following command to set only the selected output to 0 or 1.
Command: SET,OWD,OUT,OWD-number, output value
Example: set,owd,out,2,1,1 => OWD number 2, output 2 is switched to "On". After switching the output, the new
status is output as confirmation.
10.2
Switching of all output relays (Port)
There are applications and modules where it is necessary to switch all outputs with one command.
With only one command, all outputs of the 1-wire block are set to a certain state, which means that the previous
output status will be overwritten.
The 1-wire controller / the 1-wire gateway takes over the command adaptation to the connected module 8-fold
digital output 8.
The output value is output as decimal value 0-254. Each relay output has a value that is summed up.
Output 1 = 1, output 2 = 2, output 3 = 4, output 4 = 8, output 5 = 16, output 6 = 32,
Output 7 = 64, output 8 = 128.
If, for example, you want to switch outputs 1, 3 and 5 to 1, add the output values together.
Here e.g. 1 + 4 + 16 = 21
All other relay outputs are switched to 0. If all outputs are to be set to 0 or switched off, the output value is 0.
Permissible output values for 1-Wire digital outputs: 0 - 255
Command: SET,OWD,OUTH,OWD-number, output value
Example: set,owd,outh,2,15 => OWD number 2, output 1 to 4 is switched to "On
After switching the output, the new status is output as confirmation.
10.3
Data output 1-Wire controller / 1-Wire gateway
For the 8-fold digital output 8 the following data are output for the relay outputs.
The status and the output value are output as decimal value 0-254 and in a second data set binary with 0 and 1.
Each output has a value that is summed up in each case.
The data of OWDx_3 and OWDx_4 are relevant for this module.
Relay output and status:
Output 1 = 1, output 2 = 2, output 3 = 4, output 4 = 8, output 5 = 16, output 6 = 32, output 7 = 64, output 8 = 128.
Data output:
1_OWD1_1|7
=> Controller No._device no._data record | status decimal value
1_OWD1_2|00000111 => Controller No._device no._data record | binary display of status
1_OWD1_3|7
=> Controller No._device no._data record | decimal value output
1_OWD1_4|00000111 => Controller No._device no._data record | binary display output
Further information on possibilities and commands can be found in the current 1-Wire Controller /1-Wire Gateway
documentation.

Operating conditions
The device may only be operated at the specified voltages and ambient conditions. The device may only be
used in dry indoor areas.
If condensation forms inside the unit, allow at least 2 hours for the unit to acclimatize. Do not operate the
module in an environment in which flammable gases, vapors or dusts are present or could be present. The
building group can be operated only under the supervision of an electrically skilled person.
In industrial facilities, the accident prevention regulations of the federation of industrial professional
associations for electrical installations and equipment must be observed.
