Store to EEPROM

The actual parameters will be stored to the internal memory (except learned values,

which are not stored). When the power is switched off and on, these parameters will

immediately be loaded and used.

Range extend

This function allows it to measure targets also in a bigger distance. The K-XC1 module

still outputs 256 distance information points, but these points are calculated of several

distances. If you set Range extend to 1 always 2 measured points are converted into 1

displayed point what extends the measurement range by a factor of 2:

0

Standard mode. Each measured point corresponds to the displayed point

1

Extend by 2: 2 measured points are combined to 1 displayed point

2

Extend by 4: 4 measured points are combined to 1 displayed point

3

Extend by 8: 8 measured points are combined to 1 displayed point

It is not recommended to use this function (set a value different of 0) without a high-gain

antenna.

Option Data

The K-XC1 module has several internal settings which can be activated or deactivated by

this value. Option Data is a bit-coded 8bit value, where currently 2 bits are used:

Bit 7: Control Speed of digital output (0=115’200 Bit/s, 1=921’600 Bit/s)

Bit 6: Data Stream Content (0=Include Logarithmic Magnitude, 1=Only I/Q is sent)

Digital Output of Datastream

Software version V0.20 and higher also support a digital output. This can be selected in

the main menu. When activated, the analog output is disabled and instead of this the

digital representation of measured values is presented on the output connector:

Pin 4: Digital signal output, serial format, 3.3V levels

Pin 6: Ground

The signal voltages are 3.3V, so to connect a PC the use of a level-shifter or a USB-

converter

is

necessary.

On this port the following data are permanently sent:
