1. Overview
This document contains information about the hardware and software interface between an
AeroComm PKLR2400 Radio and an OEM host. Information includes the theory of operation, system
issues, and a basic command set for operational control of the system and radio.
The Radio is designed to allow flexibility at the hardware interface level with a minimum number
of actual hardware pins connecting the radio and the OEM Product. The radio is controlled by a Dallas
87C520 microcontroller providing program storage. A separate EEPROM provides user definable
parameter storage.
The RF system is a Client/Server (Slave/Master) architecture. Data can be transmitted from client
to server or server to client, but not from client to client, or server to server. Clients can only hear servers
and servers can only hear clients.
The Serial Interface Modes provide four main serial user interfaces. This protocol provides
significant flexibility to the OEM allowing them to provide data in many forms including packet, end
character and fixed-length with and without timeouts.
