Serial (Low Speed Data) Input Menu
The Encoder behaves as a transparent pipe and supports Low Speed Data (LSD) input in three
operating modes:
■
Row mode
– this mode provides an endless stream of data. To push a character out of the pipe,
a maximum of 80+180 are needed. This mode is active if the Time Out parameter is set to 0 and
the EOC is set to 256.
■
Timeout mode
– in this mode, any break of more than a selected time between two characters
will cause the last character to be flushed out to the pipe before the break. This mode is active
if the Time Out parameter is set to any value but 0 (i.e., non zero) and the EOC is set to 256.
■
End of File mode
– in this mode, a character signals the end of the stream and the received
buffer (including this character) is flushed out to the pipe. This mode is active if the Time Out
parameter is set to any value (including zero) and the EOC is greater than 0 but less than 256.
NOTE:
Working with low speed data requires using the supplied RJ-45-to-DB-9 converter.
The Serial Inputs menu parameter allows setting the Serial LSD definitions.
