OEM7 SPAN Installation and Operation User Manual v14 68
For information about the OEM7 receiver card connectors and pinouts, refer to the OEM7 Installation
and Operation User Manual .
Important! Assemble in accordance with applicable industry standards. Ensure all Electrostatic Dis-
charge (ESD) measures are in place, in particular, use a ground strap before exposing or handling any
electronic items, including the UIC, receiver and IMU. Take care to prevent damaging or marring painted
surfaces, O-rings, sealing surfaces and the IMU.
For more information about ESD practices, see the
OEM7 Installation and Operation User Manual .
Use the following steps to install the OEM7 receiver and UIC:
1. Mount the components of the SPAN system. See Mount the SPAN System Components below.
2. Connect the IMU to the UIC. See Connect the IMU to the UIC on the next page.
3. Connect the UIC to the OEM7 receiver. See Connect the UIC to a receiver on the next page.
4. Connect power to the UIC and OEM7 receiver. See Connect Power to the UIC and OEM7 Receiver on the
next page.
2.3.1 Mount the SPAN System Components
1. Mount the antenna. See Mounting the GNSS Antenna on page 33.
2. Mount OEM7 receiver. See the OEM7 Installation and Operation User Manual for information about installing
an OEM7 receiver.
3. Mount the IMU. See Mount the IMU on page 34.
4. Install the UIC in a secure enclosure to reduce environmental exposure and RF interference. If there is suf-
ficient space, the UIC can reside in the same enclosure as the receiver.
Use M3 pan head stainless steel screws to secure the UIC to its mounting location. See UIC Mechanical
Drawings on page 272 for the UIC dimensions.
Ensure the UIC is mounted close enough to the IMU so the interface cable can reach both
devices. For the length of the interface cable, refer to the specifications for the IMU in
IMU
Technical Specifications on page 134.
Ensure the mounting location provides at least 5 mm of clearance below the board to allow for
components on the bottom of the UIC.
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
UIC which is 100 mm long and 113 mm wide, the deflection along the length must not exceed
0.75 mm and the deflection along the width must not exceed 0.85 mm.
