1.11.3 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.

1.11.4 Power Save Mode

Power Save Mode (PSM) allows a reduction in system power consumption by selectively switching parts of the

receiver on and off.

Power Save mode is not available with LEA-6R.

1.12 Configuration

1.12.1 Boot-time configuration (LEA-6A, LEA-6S)

LEA-6A and LEA-6S modules provide CFG_COM1 for boot-time configuration. This pin becomes effective

immediately after start-up. Once the module has started, the configuration settings can be modified with UBX

configuration messages. The modified settings remain effective until power-down or reset. If these settings have

been stored in battery-backup RAM, then the modified configuration will be retained, as long as the backup

battery supply is not interrupted.

UART settings can be can be configured as seen in Table 6 with the CFG_COM1 pin. Default settings in bold.

1.12.2 Configuration (LEA-6H, LEA-6R, LEA-6T)

With the LEA-6H, LEA-6R LEA-6T-0 and LEA-6T-1, configuration settings modified with UBX configuration

messages can be saved permanently. In this case the modified settings remain effective even after power-down

and don’t require backup battery supply.

LEA-6T-0 includes a serial Flash memory for storage of configuration. Saving full configurations might take

several seconds to store on LEA-6T-0. Do not power down the Module before receiving the acknowledge.

1.13 Design-in

In order to obtain the necessary information to conduct a proper design-in, u-blox strongly recommends

consulting the LEA-6/NEO-6/MAX-6 Hardware Integration Manual [1].
