l
Use COM1 for connection to a computer. COM1 uses RS-232 levels and can be connected to a
computer without additional interface circuitry.
l
Use COM2 for connection to the MIC serial port. Both the MIC serial port and COM2 use LVCMOS
levels and can be connected without additional interface circuitry.
Use the following steps to install the OEM7 receiver and MIC:
1. Mount the components of the SPAN system. See
Mount the SPAN System Components
2. Connect the IMU to the MIC. See
3. Connect the MIC to the OEM7 receiver. See
4. Connect power to the MIC and OEM7 receiver. See
Connect Power to the MIC and OEM7 Receiver
Mount the SPAN System Components
1. Mount the antenna. See
2. Mount the OEM7 receiver. See the
OEM7 Installation and Operation User Manual
for information about
installing an OEM7 receiver.
3. Install the MIC in a secure enclosure to reduce environmental exposure and RF interference. If there is suf-
ficient space, the MIC can reside in the same enclosure as the receiver.
Use the screws supplied with the MIC card to secure the MIC to its mounting location. See
on page 259 for the MIC dimensions.
Ensure the MIC is mounted close enough to the IMU so the interface cable can reach both
devices.
Ensure all standoffs are properly installed and the mounting location is flat.
The amount of board deflection (bow and twist) must not exceed 0.75%. For example, on the
MIC which is 75 mm long and 46 mm wide, the deflection along the length must not exceed
0.56 mm and the deflection along the width must not exceed 0.34 mm.
4. Mount the IMU. See
Connect the IMU to the MIC
1. Attach the IMU mounting Printed Circuit Board (PCB) to the IMU.
Ensure all the pins on the header are aligned with the holes on the mating connector.
