6. Command Set
The basic command set consists of several commands from the Host and Radio
. The command
set can be used ONLY when the radio is in Serial Interface API Mode 03 determined by the
EEPROM address at 4AH (See Chapter 7, Configuring the PKLR2400).
The command set is designed
as follows:
Command
Length
Data
Checksum
Command
-- 1 Byte. This is the actual command from the appropriate processor.
Length
-- 2 Bytes. This is the total size of the remaining data for this command. The length field
is in little endian format.(i.e. low byte/hi byte). This length does not include the checksum.
Data
-- N Bytes. The actual data associated with the command.
Checksum
-- 1 Byte. The checksum is a byte-by-byte, bitwise “EXCLUSIVE OR” of the Data
block beginning after the Length.
6.1 System Command Set Summary
The System Commands allow the user to initialize the system and perform general system analysis
when operating in API Serial Interface Mode 03.

6.1.1
Reset*
This command is issued from the Host processor to the Radio. This command provides a software
reset to the PKLR2400 Radio initializing the code at the same location as a hardware reset. This must be
followed by an RF Enable.
