Hardware Handshaking (continued)

Scan a bar code to select one of the following hardware handshaking options:

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 - The digital scanner asserts RTS before transmitting and ignores the state of CTS. The
digital scanner de-asserts RTS when the transmission completes.

RTS/CTS Option 2 - 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 (default), the digital scanner issues an error indication and discards the data.

RTS/CTS Option 3 - The digital scanner asserts RTS before data transmission, regardless of the state of
CTS. The digital 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 scanner issues an error indication and discards the data. The
digital scanner de-asserts RTS when transmission completes.
