Hardware Handshaking (continued)
•
None: Scan this bar code to disable hardware handshaking.
•
Standard RTS/CTS: Scan this bar code to select Standard RTS/CTS Hardware Handshaking.
•
RTS/CTS Option 1: If you select RTS/CTS Option 1, the digital imager scanner asserts RTS before
transmitting and ignores the state of CTS. The digital imager scanner de-asserts RTS when the transmission
is complete.
•
RTS/CTS Option 2: If you select Option 2, RTS is always high or low (user-programmed logic level).
However, the digital imager scanner waits for CTS to be asserted before transmitting data. If CTS is not
asserted within Host Serial Response Time-out (default), the digital imager scanner issues an error indication
and discards the data.
•
RTS/CTS Option 3: If you select Option 3, the digital imager scanner asserts RTS prior to any data
transmission, regardless of the state of CTS. The digital imager scanner waits up to Host Serial Response
Time-out (default) for CTS to be asserted. If CTS is not asserted during this time, the digital imager scanner
issues an error indication and discards the data. The digital imager scanner de-asserts RTS when
transmission completes.
