2.2 MIC Installation
For an IMU that cannot communicate directly to a NovAtel OEM7 receiver (e.g. SDLC/HDLC), an interface card
is required for communication. The MEMS Interface Card (MIC) provides this communication between an OEM7
receiver card and the IMU.
A MIC is required to connect the following IMUs with an OEM7 receiver: HG-1700, HG-1900 and HG-
1930. For other IMUs that require an interface card (e.g. ISA100C, LN200 or µIMU), the Universal Inter-
face Controller (UIC) is required to handle the additional power requirements. See
There are two MIC configurations: stack up and standalone. In a stack up configuration, the MIC card is moun-
ted on an OEM719 receiver. In a standalone configuration, the MIC is mounted separately from the receiver.
The MIC supports all OEM7 receiver cards for communications. The OEM719 is the only OEM7
receiver card that can be directly integrated and powered by the MIC.
2.2.1 Install a MIC in a Stack Up Configuration
In a stack up configuration, the MIC is connected to an OEM719 receiver using the 20-pin header on the
OEM719. Power and communications connections to the receiver are made through the MIC.
Important!
Assemble in accordance with applicable industry standards. Ensure all Electrostatic
Discharge (ESD) measures are in place, in particular, use a ground strap before exposing or
handling any electronic items, including the MIC, receiver and IMU. Take care to prevent
damaging or marring painted surfaces, O-rings, sealing surfaces and the IMU.
