Handshaking Protocol:
None (free running mode): In free running mode, the 3060/3080 sends data as soon as it is scanned with or without
2-way communication with the host computer.
RTS/CTS (standard modem protocol): Under this protocol, the scanner sends an RTS (request to send) and waits
for a CTS (clear to send) signal from the host computer. If there is no reply CTS signal from the host computer, the scanner
issues 1 long warning beep.
ACK/NAK (software): When the ACK/NAK protocol is used, the scanner waits for an ACK (acknowledge) or NAK
(not acknowledge) from the host computer after data transmission, and will resend in response to a NAK. If the scanner
buffer is full, the 3060/3080 issues 4 long warning beeps, and stops scanning data.
We recommend adding a Record Suffix to the scanned data when using the ACK/NAK protocol. This helps identify
multiple data records in each transmission.
Xon/Xoff: When the Xon/Xoff protocol is used, the 3060/300 unconditionally transmits scanned data to the host
computer. If the host computer issues a Ctrl-S to declare a busy condition, the 3060/3080 temporarily stores the scanned
data in its memory buffer and stop transmitting data until it receives a Ctrl-Q from the host computer. It is possible to scan
too much data before a Ctrl-Q from the host computer, which fills the scanner’s memory buffer. If this occurs, the
3060/3080 issues 4 long warning beeps to indicate the memory buffer is full, and it stops scanning data.
We recommend adding a Record Suffix to the scanned data when using the Xon/Xoff protocol. This helps identify multiple
data records in each transmission.
