(1) Communications protocol
You can select either non-acknowledge mode or ACK/NAK mode.
Non-acknowledge mode (default)
If the CTS signal is at a high level (Enable transmission), the scanner transmits bar code data read.
Note: The configuration software provides CTS timeout settings from 100 ms to 9.9 s in 0.1-second increments.
Note: The time length required from the issue of the RTS output level change request at the host computer to the detection
of the CTS input level change at the scanner may vary depending upon the processing capability and conditions of the host
computer.
ACK/NAK mode
If the CTS signal is at high level (Enable transmission), the scanner transmits bar code data read. After that, the scanner
waits for and then processes a response.
Note: The configuration software provides CTS timeout and ACK/NAK response settings from 100 ms to 9.9 s in
0.1-second increments.
Note: The time length required from the issue of the RTS output level change request at the host computer to the detection
of the CTS input level change at the scanner may vary depending upon the processing capability and conditions of the host
computer. The same applies to the time length required from the issue of the response at the host computer to the receipt at
the scanner.
(2) CTS signal monitor
The configuration software ScannerSetting* provides two choices of the CTS signal monitor--enable or disable.
Enabling the CTS signal monitor does not output data when the RTS signal at the host is disabled.
