HMR3200/3300
COMPASS DEMONSTRATION KIT
The HMR3200 or HMR3300 Demo kit includes additional hardware and Windows software to form a development kit for
electronic compassing. This kit includes the HMR3200 orHMR3300 Printed Circuit Board (PCB) module as a daughter
board, a TTL to RS-232 motherboard with a D9 serial port connector, 6’ serial port cable with attached AC adapter power
supply, and a Windows demo software CD with documentation. The cable is a 4-wire design with pins 2 and 3 NOT
flipped (DTE to DCE, not null modem) with pin 5 as the ground reference. Pin 9 is the unregulated positive voltage
reference and is factory connected to the AC adapter. Either cable side may be used for the compass demo kit or
computer serial port.
The AC adapter is a universal type and factory set for 120 VAC input, 9 volt DC output, and positive polarity. Users can
rewire the cable for battery operation for remote usage. Batteries chosen must apply the required 6 to 15 volt supply
range with at least 24mA current capability. If compact 9 volt batteries are used, it is recommended that two batteries of
the same chemistry be wired in parallel to have reasonable operational life.
The TTL to RS-232 motherboard is designed to handle only unregulated power supply voltages and routes the supply
directly to the V+ pin of the HMR3200 or HMR3300 daughterboard. The electronics on the motherboard convert the RX
and TX 5 volt logic to the ±6 volt RS-232 drive logic for computer serial ports.
