to be monitored. If the system does not work as expected this is useful to see if the commands

L - Look For Sensors: Not Available In Built In Menu
This option is used to automatically search for SDI-12 sensors connected to the unit. This only
looks for sensors connected to the SDI-12 port, not those connected to an RS232 port using the
H-4191 SDI-12 to RS232 interface. This will first search the addresses 0 to 9 and then pauses to
see if the user wants to look for sensors using the upper and lower case letters as addresses. If a
sensor is found it will list its response to the ID command which should include the manufactures
name, model number of the sensor, and version information.
If two or more sensors use the same address they will not be recognized and the conflict must be
detected and resolved by the user. Using the full screen SDI-12 mode may help find sensor
conflicts.

different points in the the network to see that nothing is overloading the data line and that it is
connected correctly.
