RS-232 Interface 7 - 13 Hardware Handshaking (continued) • None: Scan this bar code to disable hardware handshaking. • Standard RTS/CTS: Scan this bar code to select Standard RTS/CTS Hardware Handshaking. • RTS/CTS Option 1: If you select RTS/CTS Option 1, the digital scanner asserts RTS before transmitting and ignores the state of CTS. The digital scanner de-asserts RTS when the transmission completes. • RTS/CTS Option 2: If you select Option 2, RTS is always high or low (user-programmed logic level). However, the digital scanner waits for CTS to be asserted before transmitting data. If CTS is not asserted within Host Serial Response Time-out (default), the digital scanner issues an error indication and discards the data. • RTS/CTS Option 3: If you select Option 3, the digital scanner asserts RTS prior to any data transmission, regardless of the state of CTS. The digital scanner waits up to Host Serial Response Time-out (default) for CTS to be asserted. If CTS is not asserted during this time, the digital scanner issues an error indication and discards the data. The digital scanner de-asserts RTS when transmission is complete. *None Standard RTS/CTS RTS/CTS Option 1 RTS/CTS Option 2 RTS/CTS Option 3
