5.5 ARQ Mode Operation

In ARQ operation one station (information sending station) sends
data to another in block by block, then listens the acknowledge
signal between blocks from the information receiving station which
requests either the next block or retransmission of the last block if
there is error. The request may be repeated up to 32 times, until the
complete block is received free of error.

tion menu appears.

2. Select a station. (Station must be registered for the ARQ mode).

Press the [Enter] key. The message "Calling Station" appears.

If the message "Station calling suspended. Check radio and
interconnections. Press any key to escape." appears, check both
radio's power and interconnections between the radio and the
DP-6.

3. When an acknowledge signal is detected, "Connect" appears

in inverse video on the communication status display (see next
page).

Note:

If signal conditions are poor, connection may take a

while. If the line could not be connected in one minute, calling
stops and "Calling failed" appears. Try step 2 again one minute
later. Should signal conditions worsen during message
transmission, "Error" appears in inverse video and 30 seconds
later the line is disconnected.
