Rs232 Receiver Time-Out; Rs232 Handshaking - Honeywell N4680 User Manual

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 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 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
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.
