Page 100: Chapter 6 Can Bus
CAN transceivers and proper bus terminations. See CAN Controller Ports on page 218 for an example of a CAN transceiver circuit. On the OEM719, CAN1 is multiplexed with user VARF and EVENT2, so the following commands must be issued before enabling CAN1:...
Page 101: Default Configuration
PGNCONFIG command: configures the NovAtel-proprietary NMEA2000 messages (change the PGN and its priority) CCOMCONFIG command: configures the parameters used by the NovAtel command inter- face to interact with the CAN Bus CCOM ports with a lower port number have a higher transmission priority.
Page 102: Configuration Notes
Chapter 6 CAN Bus 1. Use the J1939CONFIG command to specify J1939 NAME and desired address. 2. Use the CANCONFIG command to place the receiver on bus. 3. Optionally, use the J1939STATUS log to monitor CAN status on the receiver. 6.2.1 Configuration Notes The J1939CONFIG and CANCONFIG commands can be entered in any order.
Page 103: Example Of Detecting An Address Claim Failure And Reconfiguring
J1939CONFIG command. 6.3 NMEA2000 Logging OEM7 receivers support both a subset of the standard NMEA2000 PGNs, as well as NovAtel pro- prietary PGNs. All NMEA2000 logs are configured using the LOG command, where the COM port is a CAN port (CCOM).
Page 104: Example Of Nmea2000 Log Configuration
It is strongly recommended to RESET the receiver after using the PGNCONFIG com- mand. This prevents PGN ambiguities and conflicts. 6.4 Corrections Over CAN All NovAtel supported correction types are supported over CAN ports (CCOM). To send or receive corrections: 1. Configure the CAN Bus. See Configuring the CAN Bus on page 101.
Page 105: Example For Receiving Corrections From Any Source
The CCOM port requires special configuration and has the following limitations: A single CCOM port cannot be used for both Binary and ASCII / NovAtel ASCII messages. A single CCOM port cannot be used for both Binary messages and corrections.

Page 214: Event_In, Event_Out And Pps Signal Protection
This design has been used to protect EVENT_IN sig- nals from EN61000-4-5 induced surges up to 2kV on several NovAtel enclosure products. If nano- second-level timing is critical to the application, this protection circuit may be unsuitable, as it causes a timing shift of a few microseconds to the EVENT signal (heavily dependent on tem- perature).
Page 215: Table 46: Event_In, Event_Out And Pps Pin Designation
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.

Page 216: Position Valid (Pv) Led Driver
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 217: Communication Ports
APPENDIX E Receiver Card Interface Examples E.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.

Page 225: Appendix F Importance Of Antenna Selection
APPENDIX F Importance of Antenna Selection An antenna behaves both as a spatial and frequency filter, therefore, selecting the right GNSS antenna is critical for optimizing performance. An antenna must match the receiver’s cap- abilities and specifications, as well as meet size, weight, environmental and mechanical spe- cifications for the intended application.
Page 226: Figure 64: Plot Of Good And Poor Antenna Phase Center Variation Over Elevation Angle
APPENDIX F Importance of Antenna Selection Figure 64: Plot of Good and Poor Antenna Phase Center Variation over Elevation Angle 0-90° Many users can accept accuracies of less than a metre so these small phase center vari- ations cause a negligible amount of position error. But if you require high precision, Real Time Kinematic (RTK) receivers can achieve position accuracies of 2-4 cm and a few mil- limetres of phase center error translates to a 10-15% error in reported position.

The table below highlights some of the important desirable features needed for a GNSS antenna based upon the user’s application.

APPENDIX H Electrostatic Discharge (ESD) Practices Various electrical and electronic components are vulnerable to ESD. These include discrete com- ponents, hybrid devices, Integrated Circuits (ICs) and Printed Circuit Boards (PCBs) assembled with these devices. H.1 Handling ESD Sensitive Devices ESD sensitive devices must only be handled in static controlled locations. Some recom- mendations for such handling practices follow: Handling areas must be equipped with a grounded table, floor mats and wrist strap.
Page 233: Prime Static Accumulators
APPENDIX H Electrostatic Discharge (ESD) Practices Do not allow chargeable plastics, such as binders, within 0.6 m of unshielded PCBs. Do not allow a PCB to come within 0.3 m of a computer monitor.
