RS232 Handshake
RS232 Handshaking allows control of data transmission from the scanner using
software commands from the host device. When RTS/CTS is turned Off, no data
flow control is used.
Flow Control, No Timeout
: The scanner asserts RTS when it has data to send, and
will wait indefinitely for CTS to be asserted by the host.
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 35) 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 time-
out by scanning the barcode below, then setting the timeout (from 1-5100 milli-
seconds) by scanning digits from the
