4 PARAMETER ISSUES AND DEFINITIONS

4.1 RADIO AND SERIAL COMMUNICATION CONTROLS

DLCC communication can be controlled by several parameters depending on

whether it is a Client or Server. DLCC can act as both Client and Server.

The following table summarizes which parameters are controlled by the Client and

which ones are controlled by the Server.

Client (Transmitter)

controlled parameters:

Server (Receiver)

controlled parameters

Transmission Mode ACK/NACK Protocol

ACK/NACK From Remote Host Handshaking

FIFO

Handshaking

Single Store

NOTE

To avoid incorrect interpretation of ACK characters, ACK/NACK

Protocol and ACK/NACK From Remote Host cannot be

simultaneously enabled on the same DLCC.

To help understand the various communication control possibilities among the

different communication modes, we will analyze the communication control

parameter settings for the following 3 cases:

1) DLCC acting as Server

2) DLCC acting as Client (like an RF device)

3) DLCC as client / server
