This section describes how to configure the Prime in your host system. To install the Prime into
your system, follow these steps:
Make electrical connections to the Prime.
Evaluate the Prime using the included StudioPrime program or terminal emulation
software, such as Tera Term or RealTerm, to ensure the compass generally works
correctly.
Choose a mounting location in the host system.
Mechanically mount the Prime in the host system.
Perform a field calibration.
4.1 Electrical Connections
The Prime incorporates both a 16 pin ribbon connector (topside of PCB) and a 9 pin Molex
connector (bottom side of PCB) for connecting the unit to the user’s system. The user should
decide which connector they want to use, and only use this connector. The Prime will not
function properly if commands are sent on both connectors. The pin-out for both connectors
is given below in Table 4-1. Pin #1 for both connectors is indicated in Figure 3-1.
