... RXD 7 8 The HMR3100 board is 0.77” on each side with eight pins in groups of four spaced at 0.6” apart in wide-DIP format. Seated height is approximately 0.275”. See Figure 1 for further mechanical details. USART Communication Protocol HMR3100 module communicates through binary data and ASCII characters at four selectable baud rates of 2400, 4800, 9600, or 19200 ...

... HMR3100 The HMR3100 sends data via the TXD line (Pin 5) in standard serial bus form at logic levels, but uses the RTS (Pin 3) and RXD (Pin 6) to select the three active modes of operation. Normally RTS and RXD input lines are left high until data or hard-iron calibration is needed from the HMR3100 ...

... HMR3100 Calibration Mode When the host processor pulses low the RTS pin, and sends the RXD pin to a low logic level, the HMR3100 is in hard-iron calibration mode. This calibration is only for nearby magnetized metals (hard-iron) that are fixed in position with the HMR3100 moderate rate (5 seconds or more per rotation), rotate the HMR3100/host assembly two complete circles (on a flat, non-magnetic surface if possible) to allow the HMR3100 to take measurements for compass calibration ...

... HMR3100 daughter-board. A nine-volt battery clip is included, but other DC input voltages between 7 and 15 volts may be used. Supply currents are nominally around 8mA plus the HMR3100 current draw. The RS-232 motherboard also contains a six-contact modular jack (RJ-11) for a compact RS-232 interface to a personal computer serial port ...
