Eight key identifiers can be set using iButtons command (section
Digital inputs setting
) or in the
Configurator on Settings\Digital inputs tab. You should enter 4 lower bytes of iButton key
number without checksum, in hexadecimal system.
For example, full key hexadecimal number:
09 91 02 0С 00 00 00 5С, where
09 – type of device (in this case, it is DS1982, for DS1990 – 01),
91 02 0С 00 00 00– unique number,
5C – the checksum.
In this case, 91 02 0С 00 must be entered.
By identification key applying with one of the certain identifiers, a correspondent bit will be set
in iButton connection status field. You may control it on the Device tab in the Configurator.
By using a microSD card, you may edit a list of trusted keys with the help of the AddKey, DelKey
commands (section
Digital inputs settings
). You can also connect the card to the computer and
edit the list in the Configurator on the Trusted iButton keys tab. In case of connection of one of
the enlisted IK, a correspondent bit will be set in the Device Status field.
Connecting DS18S20 (DS1820, DS18B20) thermometers and
DS1923 temperature and humidity sensors
It is possible to connect up to 8 DS18S20 thermometers and 8 DS1923 sensors. To use the
sensors connect them to 1-Wire and GND contacts (
Contacts description
) and activate the
corresponding protocol items (
Server exchange protocol settings
). There is no any linkage
between a thermometer or humidity sensor and a certain tag cell in the protocol. All data are
stored in memory cells in a definite order: from a lower tag to a higher tag. If the number of
cells exceeds the number of thermometers of one type, the extra higher cells will contain the
data which correspond to disconnected sensor state.
By temperature sensor turning off the thermometer field shows disconnection (-128ºC).
By humidity sensor turning off the humidity field shows disconnection (0%).
