PARAMETER ISSUES AND DEFINITIONS

Case 2 – DLCC as Client (like an RF device)

HOST

Client

Figure 6 - DLCC Client

In the figure above, DLCC is a Client (as an RF device). The following parameters

may be set depending on the application:

STAR

Modem™ - ACK/NACK = enabled

STAR-System™ - Rx / Tx = enabled

• If DLCC - Transmission Mode = 1 way

ACK/NACK from Remote Host = disabled

FIFO = disabled

Handshaking = modem (RTS/CTS)

In this case, DLCC sends data (messages) to the Remote Host. The special

case of FIFO disabled blocks transmission until an acknowledgement is received

from Host. Because ACK/NACK is enabled for STAR

Modem™, only after this

has received an ACK from the Remote Host does it acknowledge reception

(Empty Answer to DLCC).
