Table of Commands available for LOG08
Commands and parameters are not case-sensitive
Using the SET Command
The SET command has multiple parameters.
Update Interval determines the time between sensor readings. Set to 0 to stop polling. Enter the time in decimal minutes.
F or C Display determines how temperature readings are displayed. Enter F for Fahrenheit or C for Celsius.
Serial # Display - set to Yes if you want LOG08 to display the 1-wire ID of all sensors.
Wind Dirn Reverse - set normally to N. Set this to Y if you accidentally installed the wind direction PCB upside down in your weather station OR if you want to display wind direction as the FROM direction instead of the TO direction.
Set Clock - input the current day (Sunday = 01, Saturday = 07), hour, minute and second. Hours are expressed in 24 hour (military) format only.

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 numerous commands (the <sensorid> parameter shown in the instruction set). The sensor numbers in the scan output are sequential numbers for each type of sensor.
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.
Letters following the DS2423 and DS2438 indicate the TYPe of sensor equipped. This is a manual input and will be set following first discovery of the sensor via the INI command, and also following a power-up of the LOG08 for the DS2423 sensors that do not have built-in battery backup. The letters designate the sensor type per the following table.
Following a display of the sensors installed, the output of the DIS display then shows the LOG08 settings that you entered via the SET command then the logging device ID. The DEBug mode is then shown. To turn on or off the DEBug mode, use the DEB command.
Following that, the DIS display then checks to see if all temperature sensors are parasitically or locally powered. If ANY temperature sensor connected to the 1-Wire bus is set to parasitic mode, then the display will show "some sensors parasitic powered". The same display will result of ANY DS2438 devices are present on the 1-Wire bus.
Following that display the DIS output proceeds to show how many temperature sensors are installed, by type. The DS18B2 type indicates a DS18B20 sensor. The DS1820 type is valid for DS1820, DS18S20 and DS1920 sensors.
The TMP Output Display
The example above shows a typical output from the poll cycle. The day and time are displayed followed by the results of the output from each sensor.
