RS-232 Parameter - Hardware Handshaking

To prevent scanned information from being lost during transmission, your host device may require an RTS/CTS signal. When the RTS/CTS (Request To Send/Clear To Send) is enabled, the scanner will output an RTS signal and wait for a CTS signal before any data is transmitted. The default setting of RTS/CTS is disabled. If necessary, scan the ENABLE RTS/CTS bar code.

Enable RTS/CTS

RS-232 Parameter - Software Handshaking

For control of the data transmission process, use ACK/NAK or XON/XOFF instead of or in addition to the RTS/CTS hardware handshaking option.

Enable ACK/NAK

S H 2

** Disable ACK/NAK

When this option is enabled, the scanner will not scan again unless an ACK (ASCII 06H) is received after transmission of a bar code. If an

NAK (ASCII 15H) is received, the scanner will retransmit the bar code.

S H 1

Enable XON/XOFF

S H 4

** Disable XON/XOFF

When this option is enabled, the scanner will stop transmission whenever an XOFF (ASCII 13H) is received. Transmission will resume after an XON (ASCII 11H) is received.
