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).
