8 - 12 DS6707 Digital Imager Scanner Product Reference Guide
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 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: When Option 2 is selected, 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: When Option 3 is selected, 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 is complete.
