1.12.4 Display Data Channel (DDC)

The I

C compatible DDC interface can be used either to access external devices with a serial interface EEPROM or

to interface with a host CPU. It is capable of master and slave operation. The DDC interface is I

C Standard Mode

compliant. For timing parameters consult the I

C standard.

The DDC Interface supports serial communication with u-blox wireless modules. See the specification of

the applicable wireless module to confirm compatibility.

The maximum bandwidth is 100kbit/s.

1.12.4.1 External serial EEPROM

NEO-6 modules allow an optional external serial EEPROM to be connected to the DDC interface. This can be

used to store Configurations permanently.

For more information see the LEA-6/NEO-6/MAX-6 Hardware Integration Manual [1].

Use caution when implementing since forward compatibility is not guaranteed.

1.14 Power Management

u-blox receivers support different power modes. These modes represent strategies of how to control the

acquisition and tracking engines in order to achieve either the best possible performance or good performance

with reduced power consumption.

For more information about power management strategies, see the u-blox 6 Receiver Description

including Protocol Specification [2].

1.14.1 Maximum Performance Mode

During a Cold start, a receiver in Maximum Performance Mode continuously deploys the acquisition engine to

search for all satellites. Once the receiver has a position fix (or if pre-positioning information is available), the

acquisition engine continues to be used to search for all visible satellites that are not being tracked.

1.14.2 Eco Mode

During a Cold start, a receiver in Eco Mode works exactly as in Maximum Performance Mode. Once a position

can be calculated and a sufficient number of satellites are being tracked, the acquisition engine is powered off

resulting in significant power savings. The tracking engine continuously tracks acquired satellites and acquires

other available or emerging satellites.

Note that even if the acquisition engine is powered off, satellites continue to be acquired.

For information on using active antennas with NEO-6 modules, see the LEA-6/NEO-6 Hardware Integration Manual [1].
