Connect Power to the MIC
Connect a +10 to +30 VDC power supply to the power connector (P101) on the MIC. See
page 262 for pinout information for the power connector.
This connection provides power to the MIC, the OEM719 and the IMU.

All signal I/O with the exception of the USB port are at LVCMOS levels. To connect the MIC to devices
that use other signals levels, such as a computer with an RS-232 serial port, an interface circuit that con-
verts LVCMOS to the other signal level must be used.
Use a twisted pair for the USB port connection and keep the wires as short as possible.
2.2.2 Install a MIC in a Standalone Configuration
In a standalone configuration, the MIC is mounted separately from the OEM7 receiver.
