SPAN Installation

Chapter 2

2.3.5.2Connect a Computer Using a USB Connection

The SPAN-IGM USB port is available on the AUX connector. See Figure 4, Typical SPAN-IGM Set Up – USB Port on page 17.

If you are using a NovAtel interface cable (part number 01019015):

1.Connect the interface cable to the AUX connector on the SPAN-IGM.

2.Connect the USB connector on the cable to the USB port on the computer.

If you are creating a custom interface cable, refer to Appendix A, Technical Specifications on page 52 for the AUX connector pin out.

2.3.6Connect I/O Strobe Signals

The SPAN-IGM has several I/O strobe signals that enable it to be part of an interconnected system composed of devices that need to be synchronized with each other. For example, you could connect the SPAN system to an aerial camera in such a way that the SPAN system records its position whenever the shutter button is pressed.

The SPAN-IGM supports the strobe signals described in Table 2, I/O Strobe Signals. These signals are accessed from the AUX connector on the SPAN-IGM using a NovAtel interface cable (part number 01019015) or a custom cable. See Appendix A, Technical Specifications on page 52 for information on signals, wiring and pin-out information of the AUX port and the interface cable.

Signal

 

Descriptiona

 

Event1

An input signal for which a pulse greater than 150 ns triggers certain logs to be

 

(Mark1)

generated. Polarity is configurable using the MARKCONTROL command.

 

 

The Mark1 input is not available if the COM3 serial port has been enabled. See

 

 

COM3 Serial Port on page 22.

 

 

 

 

 

Event2

An input signal for which a pulse greater than 150 ns triggers certain logs to be

 

(Mark2)

generated (see the MARK2POS and MARK2TIME logs). Polarity is configurable

 

 

using the MARKCONTROL command.

 

 

 

 

 

PPS

A time synchronization output. This is a pulse where the leading edge is

 

(Pulse Per Second)

synchronized to receiver calculated GNSS Time. The polarity, period and pulse

 

 

width can be configured using PPSCONTROL command

 

 

 

 

 

VARF

A programmable variable frequency output ranging from 0 - 5 MHz (refer to the

 

(Variable Frequency)

FREQUENCYOUT command).

 

 

 

 

 

 

 

 

a.For information about configuring signals for SPAN use (for messages such as SETMARKxOFFSET and TAGGEDMARKxPVA), refer to the SPAN on OEM6 Firmware Reference Manual (OM-20000144). For information about configuring signals for other use (the other logs listed in this table), refer to the OEM6 Family Firmware Reference Manual (OM-20000129).

2.3.7CAN Bus

The SPAN-IGM has a CAN Bus controller that supports physical-layer signals and low-level messages specified in the appropriate sections of the J1939 and ISO11783 standards. For information about configuring the CAN Bus, refer to the application note APN-046 Configure CAN for SPAN available on our website at www.novatel.com/support/knowledge-and-learning/published-papers-and-documents/application-notes/.

The CAN Bus port is available on the MAIN connector on the SPAN-IGM using a NovAtel interface cable (part number 01019014) or a custom cable. See Appendix A, Technical Specifications on page 52 for information on signals, wiring and pin-out information of MAIN port and the interface cables.
