[. . . ] RTS/CTS Option 2: When Option 2 is selected, 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 Host Serial Response Time-out, the scanner issues an error indication and discards the data. · Product Reference Guide 41 RS-232 Hardware Handshaking -- cont. · RTS/CTS Option 3: When Option 3 is selected, the scanner asserts RTS prior to any data transmission, regardless of the state of CTS. The scanner waits up to Host Serial Response Time-out 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 de-asserts RTS when transmission is complete. *None Standard RTS/CTS RTS/CTS Option 1 RTS/CTS Option 2 RTS/CTS Option 3 42 QuickScan® L RS-232 Host Parameters Software Handshaking This parameter offers control of the data transmission process in addition to, or instead of, that offered by hardware handshaking. If Software Handshaking and Hardware Handshaking are both enabled, Hardware Handshaking takes precedence. · · None: When this option is selected, data is transmitted immediately. ACK/NAK: When this option is selected, after transmitting data, the scanner expects either an ACK or NAK response from the host. When a NAK is received, the scanner transmits the same data again and waits for either an ACK or NAK. After three unsuccessful attempts to send data when NAKs are received, the scanner issues an error indication and discards the data. The scanner waits up to the programmable Host Serial Response Time-out to receive an ACK or NAK. If the scanner does not get a response in this time, it issues an error indication and discards the data. · ENQ: When this option is selected, the scanner waits for an ENQ character from the host before transmitting data. If an ENQ is not received within the Host Serial Response Time-out, the scanner issues an error indication and discards the data. The host must transmit an ENQ character at least every Host Serial Response Time-out to prevent transmission errors. For re-transmissions of data, due to a NAK from the host, an additional ENQ is not required. XON/XOFF: An XOFF character turns the scanner transmission off until the scanner receives an XON character. There are two situations for XON/XOFF: - XOFF is received before the scanner has data to send. When the scanner has data to send, it waits up to Host Serial Response Time-out for an XON character before transmission. If the XON is not received within this time, the scanner issues an error indication and discards the data. When the scanner receives an XON character, it sends the rest of the data message. The scanner waits up to 30 seconds for the XON. · · Product Reference Guide 43 RS-232 Software Handshaking -- cont. *None ACK/NAK ENQ ACK/NAK with ENQ XON/XOFF 44 QuickScan® L RS-232 Host Parameters Host Serial Response Time-out This parameter specifies how long the scanner waits for an ACK, NAK, ENQ, XON, or CTS before determining that a transmission error occurred. *Minimum: 2 Sec Low: 2. 5 Sec Medium: 5 Sec High: 7. 5 Sec Maximum: 9. 9 Sec Product Reference Guide 45 RS-232 RTS Line State This parameter sets the idle state of the Serial Host RTS line.
