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.
8 Data, 1 Stop, Parity Even
* 8 Data, 1 Stop, Parity None
8 Data, 1 Stop, Parity Odd

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
