Setting Value
•
1 or 2 bits appended to the end of the data per each charac-
1
(default) ter to indicate End of the data.
• Set it to match the communications specifications of the ex-
2
ternal device.
•
7 Length of the data bits. Select eight or seven.
• Set it to match the communications specifications of the ex-
8
ternal device.
(default)
Setting Value
• •
Point-to-Point Point-to-Point: A basic RS-232C communication protocol
(default) that does not control communication by a control code.
• •
Point-to-Point Point-to-Point with XON/XOFF: RS-232C communication
with XOn/XOff protocol that performs data transfer control with the use of
•
ACK/NAK XOn/XOff control codes.
•
•
Polling Mode ACK/NAK: RS-232C communication protocol that per-
forms 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-F.
1 to 50 The Polling Mode Address Number. It is not used with the
V430-F.
(Default: 1)
Sets the Response Latency of the ACK/NAK Protocol (milli-
(Default: 12) seconds). If the Response Timeout for the ACK/NAK re-
sponse to data transmission is being exceeded, the code
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

(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 com-
paring with the LRC of the received data.
