RTS/CTS Option 1
: When RTS/CTS Option 1 is selected, the scanner asserts RTS before transmitting and ignores the state
of CTS. The scanner de-asserts RTS when the transmission is complete.
•
RTS/CTS Option 2
: When Option 2 is selected, RTS is always high or low (user-programmed logic level). However, the
scanner waits for CTS to be asserted before transmitting data. If CTS is not asserted within Host Serial Response Time-out,
the scanner issues an error indication and discards the data.
•
RTS/CTS Option 3
: When Option 3 is selected, the scanner asserts RTS prior to any data transmission, regardless of the
state of CTS. The scanner waits up to Host Serial Response Time-out for CTS to be asserted. If CTS is not asserted during
this time, the scanner issues an error indication and discards the data. The scanner de-asserts RTS when transmission is
complete.
