2 - 23
data transmission stops. To resume transmission, the host sends the XON
character (DC1, hex 11). Data transmission continues where it left off
when XOFF was sent.
Default = XON/XOFF Off
.
ACK/NAK
After transmitting data, the scanner waits for an ACK character (hex 06) or
a NAK character (hex 15) response from the host. If ACK is received, the
communications cycle is completed and the scanner looks for more bar
codes. If NAK is received, the last set of bar code data is retransmitted and
the scanner waits for ACK/NAK again. Turn on the ACK/NAK protocol by
scanning the ACK/NAK On bar code below. To turn off the protocol, scan
ACK/NAK Off.
Default = ACK/NAK Off
.
Communication Timeout
This allows you to set the length (in milliseconds) for a timeout for the host
ACK/NAK response. Scan the bar code below, then set the timeout (from
1-65535 milliseconds) by scanning digits from the Programming Chart,
then scanning Save.
Default = 2000 ms.
Timeout Retries
This setting limits the number of Communication Timeout retries. If the
Timeout Retries is set to 0, the transmission is terminated after the ini-
tial Communication Timeout. Scan the bar code below, then set the
