SINUMERIK 840C, OEM Version for Windows (BA)
The transmitter can append an extra parity bit to the character to be
transmitted. The receiver uses the parity bit to test for possible transmission
errors.
The total number of "ones" in the character must be even with positive parity
and odd with negative parity.
These bits define the amount of time the transmitter waits before transmitting a
new character on the line. Stop bits are, in fact, a time interval rather than
actual bits.
The number of stop bits can be set to 1 for modern devices (PCs or similar
devices).
This check box defines whether or not pin 6, on which the peripheral device
signals that it is ready, is evaluated.
The standard setting for this check box is deselected.
In this combo box you can choose the character at which the SINUMERIK
840C stops receiving data:
• M02/M03: The SINUMERIK 840C stops data transmission at every
program end character it receives.
• End character: The SINUMERIK 840C stops at the character set in the
"End of Transmission" input box.
Here you can choose between the following two options:
• CRLF: The NC terminates a block in the data output with CR LF. This is
the standard end of block identifier used in the PC sector. You should use
this end identifier if you want to edit the output files externally with a PC
word processing program.
• The NC outputs an LF CR CR at the end of a block. This end identifier is
used by older types of printer which do not have an integrated receive
buffer and which therefore have to output the received characters directly
on paper.
The following device type is presently supported:
• Punched tape: During data output, each file is provided with a special
header (% identifier) and opening and closing characters. When a
workpiece is output, the files are transmitted in appended form with no
intermediate gap. The transfer is cancelled if one of the following
conditions is fulfilled:
− Time-out: No data were received within the time allocated in the "Time-
Out" box.
− The defined end of transmission character ("Stop At" end character)
was received.
Defines the "Xon character" for character-controlled data transmission (see
"Protocol").
