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 trans-
action 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 man-
ual, 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 scan engine using software commands from the host
device. When RTS/CTS is turned Off, no data flow control is used.
Flow Control, No Timeout: The scan engine 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 scan engine 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 scan engine 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.
