MODES OF OPERATION
The LT2510 has three different types of interface modes:
• Transparent Mode
• API Mode
• Command Mode
The first two modes are used to transmit data across the RF, the third mode is used to configure the radio.
Transparent Mode
When operating in transparent mode, the LT2510 can act as a direct serial cable replacement in which RF data is
forwarded over the serial interface and vice versa. In transparent mode, the radio needs to be programmed with the
MAC 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 RX buffer until one of the following occurs:
• The RF packet size is reached (EEPROM address 0x5A)
• An Interface Timeout occurs (EEPROM address 0x58)
All parameters can be configured by entering Command Mode using either AT commands or by toggling the
Command/Data pin Low on the transceiver.
Transparent Mode is the default radio operation mode.
API Modes
API Mode is an alternative to the default Transparent operation of the LT2510 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.
The LT2510 has three API functions:
• Transmit API
• Receive API
• Send Data Complete
For additional details and examples, please refer to the API section of the manual.
Command Mode
Command Mode is used to configure and poll for status of the transceiver. Command mode can be entered by
issuing the Enter AT Command string or by setting the CMD/Data pin Low. Details of using Command Mode to
configure the LT2510 are detailed in Configuring the LT2510 section.
