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 timeout by scanning the bar code below, then setting the timeout (from 1-
5100 milliseconds) 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 trans-
mission stops. To resume transmission, the host sends the XON character (DC1, hex 11). Data transmission contin-
ues 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.
The HEC and TEC codes identified in this watermark supersede any conflicting HEC or TEC codes displayed in the drawing.
