  • Page 25 Chapter 2   Installation of OEM7 Family Receiver Cards For proper grounding and mechanical integrity, mount the OEM719 and OEM7700 with four screws. For proper grounding and mechanical integrity, mount the OEM729 with six screws. When installing cards, ensure all standoffs are properly installed.
  • Page 26 Figure 8: Mounting the High-Density, 60 Pin Connector OEM7 receivers have an area on the edge of the cards to allow the use of mounting rails. This is the area of bare copper outside of the keep-out zone. On the OEM719 and OEM7700, this area is 1.75 mm wide.

  • Page 27: Thermal Dissipation

    The OEM7 receivers have been designed to efficiently transfer heat from the receiver com- ponents into the printed circuit board. Mounting the OEM7 receiver on rails, or attaching heat sinks to the mounting areas, will transfer the heat from the receiver card to adjacent circuit boards, the enclosure or the air.

    See Receiver Card Inter- face Examples on page 173 for examples of these interface circuits. 2.9 Mounting the GNSS Antenna The OEM7 receiver is designed to operate with any of the NovAtel single, dual and triple-fre- quency GNSS antenna models. When installing the antenna: Choose an antenna location with a clear view of the sky so each satellite above the horizon can be tracked without obstruction.

  • Page 32: Connecting The Antenna To The Receiver Card

    The power to the antenna LNA is provided through the receiver’s RF port center conductor. To achieve the required input gain to the receiver, NovAtel coaxial cables are designed to introduce no more than 10 dB loss. Antenna supply over current protection limits the LNA power.

  • Page 33: Applying Power To The Receiver Card

    To restore power, power cycle the receiver. The Receiver Status word, available in the RXSTATUS log (see OEM7 Commands and Logs Reference Manual (OM-20000169)), provides more information about the cause of the problem.

  • Page 49: Glide

    1.0 3.6 GLIDE NovAtel’s GLIDE™ is a positioning algorithm for single-frequency GPS and GPS/GLONASS applic- ations. GLIDE produces a smooth position output tuned for applications where time relative accuracy (pass-to-pass) is more important than absolute accuracy. Because of this, it is well suited for agricultural applications.

  • Page 50: Steadyline

    The effect is especially evident when a receiver transitions from an RTK position mode solution to a lower accuracy “fall back” solution, such as NovAtel CORRECT PPP, DGPS, WAAS+GLIDE or even autonomous GLIDE (see Figure 16: Positioning Change Without STEADYLINE below).

  • Page 174 The 10 kΩ pullups (R5, R6) are required if the buffers are used on the EVENT_IN lines. If the buf- fers are not used, the OEM7 cards have built-in 10 kΩ pullup resistors – external pull resistors are not required.

    The PV signal may be used to indicate that the receiver card has computed a valid position. Many NovAtel enclosure products use it to drive a green LED on the enclosure. It may also be used to monitor the status of the receiver with an external microcontroller.

  • Page 176: Communication Ports

    LT L29S-N1R2-25-Z C.3 Communication Ports The COM ports on OEM7 receivers (except COM1 on the OEM729) are CMOS-level I/O pins only. These ports require the addition of an RS232 or RS422 transceiver to provide appropriate signal levels. Most RS232 or RS422 transceivers will provide some ESD protection (for harsh envir- onments, additional protection may be required).

  • Page 177: Can Controller Ports

    ±25V will be required. C.4 CAN Controller Ports OEM7 receivers provide 3.3V CMOS-level CAN controller ports. An external CAN transceiver is required. The following figure shows a typical CAN transceiver implementation. The combination of ferrite beads and small-value capacitors are not necessarily required but may provide improved EMI performance.

  • Page 178: Usb Interface

    It is imperative for signal integrity and EMI reasons that the differential data traces be routed as a 90Ω differential pair. Use of a small-value common-mode choke (as shown in Figure 56: OEM7 USB Device Interface Example below) may improve the radiated emissions performance (but should not be necessary).
