The ZB2430 transceiver module interfaces to the OEM Host via an asynchronous 3.3V serial UART interface; allowing the module to be easily integrated into any 3.3V system without requiring any level translation. The module can communicate with any logic and voltage compatible UART; or to any serial device with an additional level translator.

I N T E R F A C E M O D E S

The ZB2430 has two different types of interface modes:

•Transparent Mode

•API Mode

T r a n s p a r e n t M o d e

When operating in Transparent Mode, the ZB2430 can act as a direct serial cable replacement in which received RF data is forwarded over the serial interface and vice versa. Additionally, many parameters can be configured using either AT commands or by toggling the Command/Data pin on the transceiver. In transparent mode, the radio needs to be programmed with the Network Address of the desired recipient. The destination address can be programmed permanently or on-the-fly.

When Transparent Mode is used, data is stored in the TX buffer until one of the following occurs:

•The RF packet size is reached (EEPROM address 0x5A)

•An Interface Timeout occurs (EEPROM address 0x58)

A P I M o d e

API Mode is an alternative to the default Transparent operation of the ZB2430 and provides dynamic packet routing and packet accounting abilities to the OEM Host without requiring extensive programming by the OEM Host. API Mode utilizes specific frame-based packet formats; specifying various vital parameters used to control radio settings and packet routing on a packet-by-packet basis. The API features can be used in any combination that suits the OEM’s application specific needs.

API Mode provides an alternative method of configuring modules and message routing at the OEM Host level; without requiring the use of Command Mode. The ZB2430 has three API functions:

•Transmit API

•Receive API

•API Send Data Complete

For additional details and examples, please refer to the API section on page 41.
