DATA FORMATS
The HMR2300 transmits each X, Y, and Z axis as a 16-bit value. The output data format can be either 16-bit signed binary
(sign plus 15 bits) or a binary coded decimal (BCD) ASCII characters. The command *ddA will select the ASCII format
and *ddB will select the binary format.
The order of ouput for the binary format is Xhi, Xlo, Yhi, Ylo, Zhi, Zlo. The binary format is more efficient for a computer to
interpret since only 7 bytes are transmitted. The BCD ASCII format is easiest for user interpretation but requires 28 bytes
per reading. There are limitations on the output sample rate (see table below) based on the format and baud rate
selected. Examples of both binary and BCD ASCII outputs are shown below for field values between ±2 gauss.

The ASCII characters will be readable on a monitor as sign decimal numbers. This format is best when the user is
interpreting the readings.
