5.2.1. DIS output explanations
Sensor numbers do not necessarily match up with the output from the regular
sensor output readings. This is intentional. The sensor numbers in the DIS
output are the memory locator and are used by the DEL and RST commands.
The sensor numbers in the scan output are sequential numbers for each type of
sensor.
The Sensor numbers from the DIS display are also used for displaying when a
sensor is removed or added to the 1-Wire bus. For instance:
>MON 09:52:34
Missing Sensor #04 [9900080049199310]
Would indicate that the 4
th
sensor in the DIS display was disconnected.
>MON 09:57:01
Restored Sensor #04 [9900080049199310]
Would indicate that the 4
th
sensor in the DIS display had been re-connected.
In the remainder of the DIS display, an OK will be displayed following the sensor
type to indicate that the Cyclic Redundancy Counter (CRC) checksum of the
sensor's serial number is good. If the serial number has a bad CRC, an NG will
be displayed. The checksum is validated during the output of the sensor display.
Following the CRC status, a P or M will be displayed to show the connectivity of
the sensor. A P is displayed is the sensor is present, and an M when it is missing
from the 1-Wire bus.
Letters following the P or M for DS2408, DS2423 and DS2438 sensors indicate
the TYPe of sensor equipped. This is a one-time manual input and will be set
following first discovery of the sensor via the INI command, and also following a
power-up of the TEMP08 for the DS2423 sensors that do not have built-in battery
backup. DS2408’s need to manually set whenever power is removed from those
sensors. DS2438’s are set once and do not lose their setting even if power is
removed. Any of these sensor types that have not been designated via the TYPe
command will have a question mark (“?”) displayed to indicate that the setting is
still required.
