RS-232 Receiver Time-Out

The unit stays awake to receive data until the RS-232 Receiver Time-Out

expires. A manual or serial trigger resets the time-out. When an RS-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 RS-232

receiver time-out by scanning 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 allows control of data transmission from the image

scanner using software commands from the host device. CTS/RTS operates in

mode 2. 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 (DC3, hex 13) to the image scanner. To resume

transmission, the host sends the XON character (DC1, hex 11). Data

transmission continues where it left off when XOFF was sent. Default = RTS/

CTS, XON/XOFF and ACK/NAK Off .
