Connect the SMART7 to Data Communication Equipment

The SMART7 can communicate with other devices in the system, such as computers serial, Wi-Fi or Ethernet ports. The SMART7 also has a CAN bus port for communication with other CAN bus compatible devices.

Wi-Fi and Ethernet are model dependent.

Serial Ports

The SMART7 has three RS-232 serial ports: COM1, COM2 and COM3. These ports are available on the 14-pin Tyco Ampseal connector. Refer to Table: SMART7 Connector Pin-out for the pin out of this connector.

Port settings (bit rate and parity, for example) are software configurable. See Communications with the Receiver for information about configuring the serial ports. Also see SMART7 Data Communication Specifications for the serial port specifications.

To connect to a serial port:

  1. Connect the SMART7 Interface cable (PN: 01019944), or a custom made cable, to the 14-pin Tyco Ampseal connector.

  2. Connect the appropriate DB9 connector (COM1, COM2 or COM3) to the serial port on the computer or other data communication device.


The SMART7 has a Wi-Fi Access Point that is enabled by default. This provides for easy connection to any laptop/tablet/smartphone with Wi-Fi capability and a web browser.

  1. Once the receiver is installed and powered, use a Wi-Fi capable laptop/tablet/smartphone to locate the SMART7 in the list of detected Wi-Fi Networks and establish a connection.

    The SMART7 PSN of the receiver (SSID) is printed on a label located by the connector. The format of the PSN is SMART7-<Receiver PSN>, e.g. "SMART7-ABCDEF1234567".

  2. When first connecting via Wi-Fi, the security key must be entered. The default security key is printed on a label on the bottom of the SMART7. The default security key is specific to that SMART7 receiver.

    Windows users: Note that your Wi-Fi security key is not a PIN. If you see an option such as Connect using a security key instead, you must click this option to enter your security key.

  3. Open up a web browser and enter NovAtel Setup & Monitor (Web), a configuration and monitoring interface hosted on the SMART7, opens.

Setup & Monitor (Web) is compatible with recent versions of Chrome, Firefox, Internet Explorer and Safari.

Cookies should always be on and never blocked on the browser being used to connect to the Wi-Fi network.

For more information about using the Setup & Monitor (Web), refer to

To change the configuration of the Wi-Fi interface, including password, refer to Wi-Fi Configuration.

Ethernet Port

The SMART7 has an M12 D-code (female) socket that supports 10Base-T/100Base-TX Ethernet for communications with external data communications equipment such as computers and data loggers. Refer to Table: Ethernet Connector Pin Outs for the pin out of this connector.

The Ethernet port supports IPv4 Internet layer, TCP/IP transport, ping and connection from a Telnet client. Users can conduct remote debugging, accept MRTCA (modified RTCA) data and download firmware. OEM7 receivers are also equipped with NTRIP Version 2.0 (Networked Transport of RTCM via Internet Protocol) client and server capability.

Refer to Ethernet Configuration for instructions on configuring Ethernet and NTRIP.

CAN Bus Port

The SMART7 has a CAN Bus port available on the 14-Pin interface connector.

To connect to the CAN Bus port:

  1. Connect the SMART7 optional accessory cable or a custom made cable, to the main 14-Pin interface connector.

    For information about the SMART7 interface cable, see SMART Antenna Interface Cable (Optional Accessory). This section also has the connector pin out and connector recommendations for making a custom cable.

  2. Connect the CAN to the CAN Bus (J5) of the SMART7 interface cable, see SMART Antenna Interface Cable (Optional Accessory).

The SMART7 CAN bus port is unterminated. If the SMART7 is at the end of the bus, then the connecting cable must have 120 ohms integrated into the cable between CAN1+ and CAN1- in close proximity to the main 14-Pin interface connector.
