5.9.4 Transmission Mode
This parameter determines whether the reader receives responses or messages from
the Host or not. In One-Way tx mode, neither Host nor cradle responds to the reader.
In Two-Way tx mode, the reader must receive a response from either the cradle or
the Host.
The cradle responds (empty message) to the reader, only after good transmission to
the Host, for the following conditions: ACK/NACK enabled, see par. 5.1.2; WEDGE or
PEN interf
ace.
For these conditions, it is suggested to prolong the Radio Protocol
Timeout, see par. 5.9.1.
Enabling Two-Way tx mode temporarily disables FIFO buffering see par. 5.1.3.
With ACK/NACK disabled, the Host responds to the reader (through the cradle) with
an answer message (message to reader display or command to reader), see par. 6.1
and the follo
wing figure.

5.9.5 Beeper Control for Radio Response
For M8300 series readers, the data entry good read tone normally results in two
beeps; the first indicates that the reader has decoded the code; the second indicates
whether BC-80X0 has received the data.
This can be changed according to the following selections:
♦ Normal: both good decode and good receptions are signaled (two beeps).
♦ Only Good Decode: only the first beep indicating a good read is signaled.
♦ Only Good Reception: only the second beep indicating a good reception is
signaled.
♦ Off: Neither good read nor good reception beeps are signaled.
For all configurations, any transmission errors will always be signaled.
