RS-232 Interface 6 - 15
RTS/CTS Option 1
If you select RTS/CTS Option 1, the scanner asserts RTS before transmitti ng and ignores the state of CTS. The
scanner de-asserts RTS when the transmission completes.
RTS/CTS Option 1
RTS/CTS Option 2
If you select Option 2, RTS is always high or low (user-progra mmed 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 (default),
the scanner issues an error indication and discards the d ata.
RTS/CTS Option 2
RTS/CTS Option 3
If you select Option 3, the scanner asserts RTS prior to any data tran smission, regardless of the state of CTS. The
scanner waits up to Host Serial Response Time-out (default) for CTS to be asserted. If CTS is not asserte d during
this time, the scanner issues an error indication and disc ards the data. The scanner de-asserts RTS when
transmission is complete.
