Rs232 Receiver Timeout; Rs232 Handshaking - Honeywell Stratos 2700 User Manual

8 Data, 1 Stop, Parity M

RS232 Receiver Timeout

The unit stays awake to receive data until the RS232 Receiver Timeout expires. A bar code read resets the timeout. When an
RS232 receiver is sleeping, a character may be sent to wake up the receiver and reset the timeout. 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
timeout 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 65535 ms. Default = 0 ms (no timeout - always on).

RS232 Handshaking

RS232 Handshaking allows control of data transmission from the scanner using software commands from the host device.
RTS/CTS Off: RTS/CTS is turned off so no data flow control is used, but RTS is still active.
RTS/CTS Off, RTS Inactive: RTS/CTS is turned off so no data flow control is used and RTS is inactive.
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.
Character-Based Flow Control, No Timeout: The scanner asserts RTS when it has a character to send, and will wait indefi-
nitely 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 3-29) 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.
Character-Based Flow Control with Timeout: The scanner asserts RTS when it has a character to send and waits for a delay
(see RS232 Timeout, page 3-29) 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.
CTS-Based Flow Control, No Timeout: When the host asserts CTS, scanning is enabled. When CTS is not asserted, scan-
ning is disabled.
RTS On: RTS only is on during transmission. CTS is ignored.
Default = RTS/CTS Off.
