RS-232 Receiver Time-Out
The unit stays awake to receive data until the RS-232 Receiver Time-Out
expires. A trigger command 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 bar code below, then scanning digits from the inside
back cover of this manual, then scanning

. The range is 0 to 300 seconds.
Default = 0 seconds (no time-out - always on).
RS-232 Handshaking
RS-232 handshaking is a set of rules concerning the exchange of data between
serially communicating devices.
If using RTS/CTS handshaking, the imager issues an active RTS signal to the
receiving device. The imager waits to send its data until it detects an active CTS
signal from the receiving device. The imager then sends its data while checking
the CTS signal before the transmission of each data character. If an inactive
CTS signal is detected at any time, the imager halts transmission until it detects
another active CTS signal. When the imager has finished transmitting data, it
issues an inactive RTS signal to the receiving device.
Default = RTS/CTS Off,
XON/XOFF Off, and ACK/NAK Off.
