below for details.
6. Connect the I/O strobe signals (optional).
See the
PwrPak7 Installation and Operation User Manual
for information about connecting I/O signals to a
PwrPak7.
7. Connect power to the IMU and receiver.
See
on page 53 for details.
8. Connect a data communication device, such a computer, to the receiver. A data communication device is
used to configure and monitor the receiver.
See the
PwrPak7 Installation and Operation User Manual
for information about connecting a data com-
munication device to a PwrPak7.
2.4.1 Connect the IMU to the PwrPak7
Connect the IMU to the COM1 or COM2 serial port on the PwrPak7. Both of these serial ports are available on
the HD26 COM PORTS connector on the PwrPak7.
IMU-CPT, IMU-KVH1750, IMU-FSAS and IMU-STIM300D
These IMUs require an additional output or input from the HD26 COM PORTS connector on the
PwrPak7 to synchronize the IMU and receiver. See
Table 16: Additional IMU to PwrPak7
If using a KVH1750 IMU, the baud rate of the IMU must be changed to 460,800 bps. For
information about changing the IMU baud rate, see
NovAtel IMU Interface Cables
An interface cable is available from NovAtel for each IMU supported by OEM7 receivers. The interface cables
provide access to the IMU power and communication signals. For information about these cables, refer to the
applicable IMU in the
PwrPak7 Cables
The following communication cable is available from NovAtel for connecting an IMU to the PwrPak7.
l
PwrPak7 IMU Cable (01019767)
This cable connects the PwrPak7 to an IMU in an IMU Enclosure (IMU-ISA-100C, IMU-ENC-LN200, IMU-
HG1900 or IMU-µIMU-IC) using the COM1 serial port.
This cable is applicable to SPAN systems with an IMU in the IMU Enclosure that do not require the EVENT
inputs, EVENT outputs, PPS output or the other serial COM ports.
l
PwrPak7 All I/O SPAN Cable (01020004)
This cable provides access to all of the signals available on the PwrPak7 26 pin D-SUB connector. Use the
COM2 connector on this cable to connect the NovAtel IMU Interface cables. This connector includes the
COM2 serial port signals and the additional signal required by the IMU-CPT, IMU-KVH1750 and IMU-FSAS.
