8 Data, 1 Stop, Parity Odd
RS-232 Receiver Time-Out
The unit stays awake to receive data until the RS-232 Receiver Time-Out expires. A trigger
command resets the time-out. When an RS-232 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 RS-232
receiver time-out by scanning the bar code below, then scanning digits from the inside back
cover of this manual, then scanning
Save . The range is 0 to 300 seconds.
Default = 0 seconds (no time-out - always on)
RS232 Receiver Time Out
RS-232 Handshaking
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 RS232 Timeout ) 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.
