RS-232 Interface 6 - 11 Hardware Handshaking The data interface consists of an RS-232 port designed to operate either with or without the hardware handshaking lines, Request to Send (RTS) and Clear to Send (CTS). Disable Standard RTS/CTS handshaking to transmit scan data as it becomes available. Select Standard RTS/CTS handshaking to transmit scan data according to the following sequence: • The scanner reads the CTS line for activity. If CTS is de-asserted, the scanner waits up to the Host Serial Response Time-out for the host to de-assert the CTS line. If, after Host Serial Response Time-out (default), the CTS line is still asserted, the scanner sounds a transmit error and discards any scanned data. • When the CTS line is de-asserted, the scanner asserts the RTS line and waits up to the Host Serial Response Time-out for the host to assert CTS. When the host asserts CTS, the data transmits. If, after Host Serial Response Time-out (default), the CTS line is still de-asserted, the scanner sounds a transmit error, and discards the data. • When data transmission completes, the scanner de-asserts RTS 10 msec after sending the last character. • The host should respond by de-asserting CTS. The scanner checks for a de-asserted CTS upon the next transmission of data. During data transmission, the CTS line should be asserted. If CTS is de-asserted for more than 50 ms between characters, the scanner aborts transmission, sounds a transmission error, and discards the data. If this communications sequence fails, the scanner issues an error indication. In this case, the data is lost and must be rescanned. If hardware handshaking and software handshaking are both enabled, hardware handshaking takes precedence. NOTE The DTR signal is jumped to the active state. None Scan the bar code below if no hardware handshaking is desired. *None Standard RTS/CTS Scan the bar code below to select Standard RTS/CTS hardware handshaking. Standard RTS/CTS

RS-232 Interface

6 - 11

Hardware Handshaking

The data interface consists of an RS-232 port designed to operate either with or without the hardware handshaking

lines,

Request to Send

(RTS) and

Clear to Send

(CTS).

Disable Standard RTS/CTS handshaking to transmit scan data as it becomes available. Select Standard RTS/CTS

handshaking to transmit scan data according to the following sequence:

•

The scanner reads the CTS line for activity. If CTS is de-asserted, the scanner waits up to the Host Serial

Response Time-out for the host to de-assert the CTS line. If, after Host Serial Response Time-out (default),

the CTS line is still asserted, the scanner sounds a transmit error and discards any scanned data.

•

When the CTS line is de-asserted, the scanner asserts the RTS line and waits up to the Host Serial

Response Time-out for the host to assert CTS. When the host asserts CTS, the data transmits. If, after Host

Serial Response Time-out (default), the CTS line is still de-asserted, the scanner sounds a transmit error,

and discards the data.

•

When data transmission completes, the scanner de-asserts RTS 10 msec after sending the last character.

•

The host should respond by de-asserting CTS. The scanner checks for a de-asserted CTS upon the next

transmission of data.

During data transmission, the CTS line should be asserted. If CTS is de-asserted for more than 50 ms between

characters, the scanner aborts transmission, sounds a transmission error, and discards the data.

If this communications sequence fails, the scanner issues an error indication. In this case, the data is lost and must

be rescanned.

If hardware handshaking and software handshaking are both enabled, hardware handshaking takes precedence.

The DTR signal is jumped to the active state.
