The LT2510 can be configured using AT Configuration Commands. These commands can be issued only in Command Mode.
Command Mode can be entered by setting pin 15 of a transceiver asserted low or by entering AT Command Mode before issuing
the Enter AT Command.

The AT Command mode implemented in the LT2510 creates a virtual version of the Command/Data pin. The “Enter AT Command
Mode” Command asserts this virtual pin Low (to signify Command Mode) and the “Exit AT Command Mode” Command asserts
this virtual pin High (to signify Data). Once this pin has been asserted Low, all AT Commands documented in the manual are
supported.

There are four types of AT Commands supported by the LT2510.    On-the-Fly commands for dynamic reprogramming of running
memory, EEPROM commands for configuring the EEPROM, Utility commands for dealing with Command Mode and Status
Commands for polling the radio for information.

While in Command mode, the incoming RF interface of the transceiver is active and packets sent from other transceivers will still
be received; however no outgoing RF packets will be sent. The transceiver uses Interface Timeout/RF Packet Size to determine
when an AT Command is complete. Therefore, there should be no delay between each character as it is sent from the OEM Host to
the transceiver or the transceiver will not recognize the command.

When an invalid command is sent, the radio discards the data and no response is sent to the OEM Host. Table 7 below shows a
quick summary of the basic configuration & diagnostic commands available on the LT2510. For detailed command information,
please refer to the command descriptions immediately following the Quick Reference Table

Utility Commands are used to enter and exit AT Command Mode and to reset the radio.

The LT2510 transceiver contains memory that holds many of the parameters that control the transceiver operation. Using the On-
the-Fly command set allows many of these parameters to be viewed and changed during system operation. Because the memory
these commands affect is dynamic, when the transceiver is reset, these parameters will revert back to the settings stored in the
EEPROM.

Status Commands are used to poll the radio for information. Status commands can be used to poll GPIOs, ADCs or to retrieve
information about the state of the network.    Status commands do not affect the operation of the transceiver aside from being in
Command Mode.
