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.
TTL Level 232 Interface
The Colibri provides a TTL level serial 232 communication link. TTL Level 232 Inverted is the
“normal” mode that allows direct communication from the Colibri to a standard PC RS-232 serial
port with the use of cable (31-001).
Non-Inverted serial TTL communication is provided to allow direct connection to a TTL UART port,
