Ethernet communications

Platform: 

OEM729, OEM7600, OEM7700, OEM7720, PwrPak7, CPT7, CPT7700, SMART7-I, SMART7-SI

Ethernet capable OEM7 receivers are equipped with a 10-Base-T/100-Base-TX Ethernet port that supports IPv4 Internet layer, TCP/IP transport and telnet. Users can conduct remote debugging, accept MRTCA (modified RTCA) data and update firmware. Ethernet capable receivers are also equipped with NTRIP Version 2.0 (Networked Transport of RTCM via Internet Protocol) client and server capability.

The Ethernet ports are Safety Extra-Low Voltage (SELV) circuits only and are suitable for connection within a building only. Do not connect them to Telephone Network Voltage (TNV) circuits.
If intra-building connections are required, or the OEM7 receiver is installed in an outdoor enclosure, a suitably rated Ethernet router or switch should be installed between the receiver Ethernet port and the network connection.

Issue the SAVEETHERNETDATA ETHA command to ensure port settings are retained after a reset and automatically used at boot time. The SAVEETHERNETDATA ETHA command is not applicable to the ICOMCONFIG and NTRIPCONFIG command settings. The SAVEETHERNETDATA ETHA command takes precedence over the SAVECONFIG command configuration.

Ethernet configuration

The Ethernet port must be configured before using. The following sections describe how to configure the Ethernet port on an OEM7 receiver. They provide the step-by-step process for connecting to the OEM7 receiver through the Ethernet interface and setting up a base/rover configuration through Ethernet connectivity. The Ethernet port connections for a computer connected to the receiver are also described for Windows 7 operating systems.

In the following sections, references to OEM7 receivers includes the PwrPak7, CPT7 and CPT7700, SMART7-I and SMART7-SI.

Ethernet is not available on the OEM719, OEM7500, SMART2, standard SMART7, SMART7-S or SMART7-W.

Required hardware

The following hardware is required to set up an Ethernet interface to an OEM7 receiver:

  • a user supplied computer with an available Ethernet, serial or USB port

  • a GNSS antenna

  • an Ethernet capable OEM7 receiver

    External Ethernet magnetics are required for the OEM7 receiver cards. The OEM7 Development Kit can be used for Ethernet communication when connected to the OEM7 receiver.

  • an RS-232 null modem cable or USB cable

  • one or two CAT5 Ethernet cables

  • a user supplied Ethernet network, hub or wired router (optional)

  • a coaxial antenna cable (50 Ω)
