RS232 Timeout

When using Flow Control with Timeout, you must program the length of the delay
you want to wait for CTS from the host. Set the length (in milliseconds) for a time-
out by scanning the bar code below, then setting the timeout (from 1-5100 milli-
seconds) by scanning digits from the inside back cover, then scanning Save.

XON/XOFF

Standard ASCII control characters can be used to tell the scanner 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 scanner, data transmission stops. To
resume transmission, the host sends the XON character (DC1, hex 11). Data trans-
mission continues where it left off when XOFF was sent. Default = XON/XOFF Off.
XON/XOFF On

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.
ACK/NAK On
