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 linear imager scanner asserts RTS before 
transmitting and ignores the state of CTS. The linear 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 linear imager scanner waits for CTS to be asserted before transmitting data. If CTS 
is not asserted within Host Serial Response Time-out, the linear imager scanner issues an error 
indication and discards the data.

RTS/CTS Option 3: When Option 3 is selected, the linear imager scanner asserts RTS prior to any data 
transmission, regardless of the state of CTS. The linear imager scanner waits up to Host Serial 
Response Time-out for CTS to be asserted. If CTS is not asserted during this time, the linear imager 
scanner issues an error indication and discards the data. The linear imager scanner de-asserts RTS 
when transmission is complete.
