Hardware Handshaking (continued)
•
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 digital scanner asserts RTS before
transmitting and ignores the state of CTS. The digital 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 digital scanner waits for CTS to be asserted before transmitting data. If CTS is not asserted
within Host Serial Response Time-out, the digital scanner issues an error indication and discards the data.
•
RTS/CTS Option 3: When Option 3 is selected, the digital scanner asserts RTS prior to any data
transmission, regardless of the state of CTS. The digital scanner waits up to Host Serial Response Time-out
for CTS to be asserted. If CTS is not asserted during this time, the digital scanner issues an error indication
and discards the data. The digital scanner de-asserts RTS when transmission is complete.
