XON/XOFF

Standard ASCII control characters can be used to tell the engine to start
sending data (XON/XOFF On) or to stop sending data (XON/XOFF Off).
When the host sends the XOFF character (DC3, hex 13) to the engine,
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.
XON/XOFF On
* XON/XOFF Off

ACK/NAK

After transmitting data, the engine 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 engine looks for more bar
codes. If NAK is received, the last set of bar code data is retransmitted
and the engine 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.
ACK/NAK On
* 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.
Communication Timeout
2-20
