RS-232 Interface 6 - 11
•
None
: Scan the bar code below if no Hardware Handshaking is desired.
•
Standard RTS/CTS
: Scan the bar code below to select Standard RTS/CTS Hardware Handshaking.
•
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.
NOTE
The DTR signal is jumpered to the active state.
