Hand Held Products 2020, 4620 RS-232 Receiver Time-Out, RS-232 Handshaking

2 - 18 IMAGETEAM™ 2020/4620 System Manual
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 bar code 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
RS-232 Handshaking allows control of data transmission from the imager 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 imager. 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/NAKOff .
