4.3.3 Compass
DMT has selected the Honeywell HMR3000 as the preferred compass device. The Honeywell
compass uses a 9-pin serial connector for communications with the AIMS radar. Power is also
provided via this connector (see drawing). The serial communications lines should be attached
to the serial I/O port on the CPU stack via the Molex connector block (pins 7,8 and 9).
