Additional Equipment Required

The following additional equipment is required for a typical CPT7 system:

  • A 9-36 VDC, fuse (2 A) protected power supply capable of at least 18 W

  • A high quality GNSS antenna, such as NovAtel’s VEXXIS GNSS-500 or GNSS-800 series antennas

    Two GNSS antennas are needed to use the integrated ALIGN heading feature (CPT7 only)

  • An antenna cable with an SMA male connector at the CPT7 end

    Two antenna cables are needed to use the integrated ALIGN heading feature (CPT7 only)

  • Four #6 size screws for mounting

  • A computer with a serial COM, USB or Ethernet port

The following equipment may also be needed, depending on the system configuration:

  • Shielded Ethernet cable

Use a serial COM or USB connection to communicate with the receiver first. This provides the ability to configure the computer and CPT7 before using Ethernet.

The following optional accessory is available from NovAtel:

CPT7 Cables

To prevent damage to both the receiver and the cables, each connector can be inserted in only one way. Also, the IO1 and IO2 connectors are keyed so that the cable can only be inserted in the connector for which it is intended.

Furthermore, the connectors used to mate the cables to the receiver require careful insertion and removal. The cables for IO1 and IO2 use push/pull connectors. The cables for RF1 and RF2 use threaded connectors. Observe the following when handling cables.

  • Make certain to use the appropriate cable for the CPT7 connector

  • Insert the connector until it is on straight and secure

  • To remove a cable, grasp it by the connector

Do not pull directly on a cable.
