RS232 Receiver Time-Out
The unit stays awake to receive data until the RS232 Receiver Time-Out expires. 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 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 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 on page 2-19) 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.
