RS-232 Word Length: Data Bits, Stop Bits, and Parity
Data Bits
sets the word length at 8 bits of data per character.
Default = 8.
Stop Bits
sets the stop bits at 1.
Default = 1.
Parity
provides a means of checking character bit patterns for validity.
Default = None.
TTL-232 Receiver Time-Out
The unit stays awake to receive data until the TTL-232 Receiver Time-Out expires.
A manual or serial
trigger resets the time-out.
When a TTL-232 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 TTL-232 receiver time-out by scan-
ning the barcode 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).
RS-232 Handshaking
TTL-232 Handshaking allows control of data transmission from the Document Reader using software
commands from the host device.
When this feature is turned
Off
, no data flow control is used.
When
Data Flow Control is turned
On
, the host device suspends transmission by sending the XOFF character
