2 - 21
Two-Direction Flow Control:
The scanner asserts RTS when it is OK for the host to transmit. The host asserts CTS
when it is OK for the device to transmit.
Flow Control with Timeout:
The scanner asserts RTS when it has data to send and waits for a delay (see
on page 2-21) for CTS to be asserted by the host. If the delay time expires and CTS is not asserted, the device
transmit buffer is cleared and scanning may resume.
Default = RTS/CTS Off.
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 millisec-
onds) 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 transmission continues where it left off
when XOFF was sent.
Default = XON/XOFF Off
.
