Wake_On_Wan; Dpr - Quectel RM510Q-GL Hardware Design

High Level (LED OFF)

4.5.4. WAKE_ON_WAN#

The WAKE_ON_WAN# is an open drain pin, which requires a pull-up resistor on the host. When a URC
returns, a 1 s low level pulse signal will be outputted to wake up the host. The module operation status
indicated by WAKE_ON_WAN# is shown as below.

Note.
The voltage level VCC_IO_HOST depends on the host side due to open drain in pin23.

4.5.5. DPR*

The module provides the DPR (Dynamic Power Reduction) pin for body SAR (Specific Absorption Rate)
detection. The signal is sent from a host system proximity sensor to the module to provide an input trigger,
which will reduce the output power in radio transmission.
