4 Controlling Operation and Data Output with RS-232C
Setting Value
•
1 or 2 bits appended to the end of the data per each
1 (Default)
•
character to indicate End of the data.
2
Set it to match the communications specifications of the
external device.
•
7 Length of the data bits. Select eight or seven.
• Set it to match the communications specifications of the
8 (Default)
external device.
Setting Value
• •
Point-to-Point Point-to-Point:
(Default) A basic RS-232C communication protocol that does not
•
Point-to-Point control communication by a control code.
•
with XOn/XOff Point-to-Point with XON/XOFF:
•
ACK/NAK RS-232C communication protocol that performs data
• transfer control with the use of XOn/XOff control codes.
Polling Mode
•
ACK/NAK:
RS-232C communication protocol that performs
communication confirmation with the use of ACK/NAK
control codes.
•
Polling Mode:
Polling Mode is a protocol used in RS-422
communications. It is not used with the V430.
1 to 50 The Polling Mode Address Number. It is not used with the
(Default: 1) V430.
Sets the Response Latency of the ACK/NAK Protocol
(Default: 12) (milliseconds). If the Response Timeout for the ACK/NAK
response to data transmission is being exceeded, the reader
will cancel/release/clear the ACK/NAK Response Wait State.
•
Disabled When enabled, error checking to verify the accuracy of
RS-232C data transmission is added. Exclusive OR for all
(Default)
•
Enabled characters following [STX] (beginning of text) up to [ETX]
(end of text). Cumulatively adds the binary sequence of all
characters to be transmitted. The result is that 1 is added
when the number of 1 is an odd number, and 0 is added
when the number is an even number. (0 is added in the case
of two instances of 1, or two instances of 0, while 1 is added
when there is only 0 or 1 instances) The data receiving side
executes the same operation and checks for errors by
comparing with the LRC of the received data.
