RS232 Receiver Time-Out
The unit stays awake to receive data until the RS232 Receiver Time-Out expires. A
manual or serial trigger resets the time-out. When an RS232 receiver is sleeping, a
character may be sent to wake up the receiver and reset the time-out. A transaction
on the CTS line will also wake up the receiver. The receiver takes 300 milliseconds
to completely come up. Change the RS232 receiver time-out by scanning the
barcode below, then scanning digits from the Programming Chart, beginning on
page 311, then scanning Save. The range is 0 to 300 seconds. Default = 0 seconds
(no time-out - always on).
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.
