Specification of protocol and supported baud rates  4.3.7.2 UART1 Binary Data Interface.
The usage of the UART1 dual interface needs to be configured in the Customer Config of the
firmware. After booting, the MCU READY pin changes from low level to high level. As start
condition, the DUAL SW input pin needs to be pre-set from the HOST by changing from high
level to low level. The DUAL STAT output pin signals high level as Binary state. In this case, the
HOST is able to transmit or receive binary data.
To change from Binary to Command state, the DUAL SW input pin needs to be toggled (low high - low level change) from the HOST:
1. The change of state is initiated by changing the DUAL SW input pin from low to high
level (set toggle switch).
2. After the DUAL STAT pin has changed the state from high level to low level, the
Command state is active and the DUAL SW input pin can be reset from high level to low
level (reset toggle).
3. The HOST is now able to send commands. After the commands have been sent, it is
recommended to change back to Binary state by toggling the DUAL SW input pin again.

The model with the Regulatory Domain FCC/IC (M/N: ENW49C01A3KF) is only intended to be used in the
countries of US and Canada because only the channels 1 ~ 11 (2412 ~ 2462 MHz) are supported in the
2.4 GHz ISM band. It is not possible to change the pre-stored Region Code in order to change the
Regulatory Domain. Thus the module labeling contains the FCC Grant ID.
17
The model with Regulatory Domain ETSI (M/N: ENW49C02A3KF) is mainly intended to be used in
European countries because the channels 1 ~ 13 (2412 ~ 2472 MHz) are supported. The Region Code is
pre-configured (using Default Config Content in Flash memory) to Regulatory Domain ETSI and thus the
module labeling does not contain the FCC ID. At the end the customer is able to change applied Region
Code by his own Customer Config Content to be stored during customer OEMs product production in the
flash memory. It means the FCC Regulatory Domain can be configured as well, but the customer has to
certify the end product by himself.
