3.12 Stat pin

The STAT pin indicates the status of the device. It can be used to drive a LED using a series

resistor. STAT pin drive capability is 10mA (loads the VCC_IO if provided externally).

The STAT pin has the following behavior.

Blink cycle

Mode

“1” - statically

module is operational “searching for a new frame”

“0” for the endurance of the

received frame.

“0” when module is receiving data from air interface. “1”

when receiving.

In practical cases will toggle at the frequency of the data

packets on the air interface.

“0” statically

Modem is in sleep1 or sleep2 mode

pin is toggled in 1s interval

Modem is in programming mode

Pin is toggled in 250ms interval

Modem has detected a fault, fault codes can be read in

the programming mode.

Table. Modes of STAT pin.

3.13 Service pin

The SERVICE pin is used to set the UART1 into a known state. Pulling this pin low will activate

the service mode and set the UART1 into 115200, n, 8, 1. This is intended for service access of

the module, to have a known serial port setting in order to access the module settings.

The pin does not affect any permanent settings, nor does it change the mode of the module.

Releasing/ driving the pin high will return serial port 1 into the configured state.

3.14 Antenna interface

The antenna interface is a 50 Ω coaxial connector. Matching networks are not included on the

module and should be placed in the host application if the antenna is not 50 Ω. The HIROSE

U.FL compatible connector is located on the TOP side of the board.
