Baud Rate: This selection sets the baud rate (the speed at which data is sent from the scanner to the host) from 300 bits per second to
38,400 bits per second. The host terminal must be set up for the same baud rate as the scanner.

Handshaking Protocol:

None (free running mode):
3
2-way communication with the host computer.
RTS/CTS (standard modem protocol):
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):
(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.
Note: The ACK/NAK and Xon/Xoff modes are not available for Manual Trigger, Low Power operation. See page NO TAG for
information about Manual Trigger, Low Power operation.
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.

RS 232 Descriptions
In free running mode, the 3060/3080 sends data as soon as it is scanned with or without
Under this protocol, the scanner sends an RTS (request to send) and waits
When the ACK/NAK protocol is used, the scanner waits for an ACK (acknowledge) or NAK
