Figure 5 –DLCC as Server

DLCC as a

Server

receives data from RF devices. The ACK/NACK Protocol

parameter can be set to assure correct communication between DLCC and the local
Host.

Assuming the RF devices are setup for 2 way transmission in STAR-System™ mode
we can analyze the following ACK/NACK protocol selections:

RF devices -

Transmission Mode = 2 ways

The Host must respond to a 2 way transmission

•

If DLCC -

ACK/NACK = disabled

there is no control of the communication between DLCC and the Local Host.
DLCC answers the RF device which initiated the 2 way transaction with DATA
received from the Local Host.

•

If DLCC -

ACK/NACK = enabled

when the Local Host receives a message correctly, it answers DLCC with the
ACK character. Only then does DLCC acknowledge the RF device which
initiated the 2 way transaction with an Empty Answer.

•

DLCC -

DATA/NACK = enabled

when the Local Host receives a message correctly, it answers DLCC with DATA.
DLCC then answers the RF device which initiated the 2 way transaction with this
DATA (i.e. command to RF device display).
