Command Data Interface Commands
Command Description
Read
Read the current value in volatile memory. If there is no volatile
value, then the non-volatile value is returned.
Write Write a new value to volatile memory.
Read NV Read the value in non-volatile memory.
Program Program a new value to non-volatile memory.
Set Default
Configuration
Set all configuration items to their factory default values.
Erase All Addresses Erase all paired addresses from memory.
Transmit Control Data Transmit a control message.
Transmit ACK Transmit an acknowledgement for received data.
Transmit AWD
Transmit an Acknowledge With Data (AWD) response with two
bytes of custom data.
Transmit IU Packet Transmit a general IU packet.
NV Update Write all NV changes to NV memory
Pair Control Initiate / Cancel RF Pairing with another module

Serial Setup Configuration for Stand-alone Operation
The serial interface offers access to a number of advanced features that
cannot be controlled through hardware configuration alone. However, not
all products need or use a microcontroller or processor, but would benefit
from some of the advanced features.
Many of the configuration settings can be written once and then used by
the module thereafter. This allows the modules to be configured through
a temporary serial connection and then operate in a stand-alone fashion
without a permanent serial connection.
For example, a product can have a small header or connector so that
the serial lines can be connected to a PC in production test. The PC
writes the configurations required by the application to the module and is
then disconnected. The module uses these configurations in its normal
operation.
