USB Communications

To communicate between an OEM7 receiver and a computer using a USB port, NovAtel USB drivers must be installed on the computer. These USB drivers are available on the NovAtel website at novatel.com/support/support-materials/software-downloads.

PwrPak7 The USB port in the COM PORTS label group can be used for communication between a computer and the PwrPak7. The USB port labeled TRANSFER can not be used for communication. It is used for data logging and transferring data from the internal memory.

USB Drivers

NovAtel USB drivers for OEM7 receivers are available for Windows 7, Window 8, Windows 10 and Linux.

The NovAtel USB drivers provide three virtual serial ports over a single USB 2.0 connection. The three virtual serial ports are available to existing Windows or Linux applications which use COM ports to communicate (for example, NovAtel Application Suite). The NovAtel USB drivers assign COM port numbers sequentially following any existing ports on the computer. For example, if a computer has COM1 and COM2 ports, the NovAtel USB drivers assign COM3 to USB1, COM4 to USB2 and COM5 to USB3.

USB communications are not suitable for use in vehicles.

A computer has several USB ports. The assignment of COM port numbers is tied to a USB port on the computer. This allows receivers to be switched without Microsoft Windows assigning new COM ports. However, if the receiver is connected to a different physical USB port, Windows detects the receiver's presence and assigns three new COM port numbers.
