44
and punctuation), select 7 data bits. For applications that require use of the full
ASCII set, select 8 data bits per character. Default=8.
3.
Stop bits
sets the stop bits at 1 or 2. Default=1.
4.
Parity
provides a means of checking character bit patterns for validity.
Default=None.
5.
XON/XOF
Standard ASCII control characters can be used to tell the reader to start
sending data (XON/XOFF On) or to stop sending data (XON/XOFF Off). When the
host sends the XOFF character (DC3, hex 13) to the reader, data transmission stops.
To resume transmission, the host sends the XON character (DC1, hex11). Data
transmission continues where it left off when XOFF was sent, Default=XON/XOFF
Off.
6.
ACK/NCK
After transmitting data, the reader waits for an ACK character (hex 06)
or a NAK character (hex 15) response from the host. If ACK is received, the
communications cycle is completed and the reader looks for more bar codes. If NAK
is received, the last set of bar code data is retransmitted and the reader waits for
ACK/NCK again.
7.
RS232 Receiver Time-out
The unit stays awake to receive 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.
8. RS232 Hardware Flow Control
It allows control of data transmission from the reader using software commands from
the host device. When RTS/CTS is turned off, no data flow control is used.
Flow Control, No Timeout
: The reader asserts RTS when it has data to sand, and
will wait indefinitely for CTS to be asserted by the host.
Two-Direction Flow Contro
l: The reader asserts RTS when it is OK for the host to
transmit. The host asserts CTS when it is OK for the devices to transmit.
Flow Control with Timeout
: The reader asserts RTS when it has data to send and
waits for a delay (see RS232 Time-out) 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.
9.
RS232 Time-out
when using
Flow Control with Timeout
, you must program the
length of the delay you want to wait for CTS from the host. Set the length (in
milliseconds) for a time-out by scanning the bar code below, then setting the timeout
(from 1-5100 milli-seconds).
