Hardware Handshaking (Cont’d)
Hardware handshaking allows you to check the readiness of the receiving device before data
is transmitted. If the receiving device is periodically occupied with other tasks, hardware
handshaking is needed to prevent loss of transmitted data. Hardware handshaking may not
be used in conjunction with software handshaking.
Select whether the scan data is to be transmitted as soon as it is available or whether
transmission follows the RTS/CTS procedure. For RTS/CTS, also select the appropriate
option.
t
RTS/CTS Option 1. The scanner asserts RTS before transmitting and ignores the
state of CTS. The scanner deasserts RTS when the transmission is incomplete.
t
RTS/CTS Option 2. 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 two seconds, the scanner issues an error indication and
discards the data.
t
RTS/CTS Option 3. The scanner asserts RTS prior to any data transmission,
regardless of the state of CTS. The scanner waits up to two seconds 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 deasserts RTS when transmission is incomplete.
