Functional overview for the K-114
Echo off
Data sent from the PC (TX) aren’t received by the PC.
Bias network
Prevents undened bus levels when line drivers are in-
active.
Greater immunity to interference
Termination
Prevents reections on the signal lines.
High Speed
Disables the RS485 driver’s slew-rate limitation.
This allows communication at higher transmission
speeds (> 250 kbps). Unlike high speed mode, the
standard mode (< 250 kbps) reduces reections on
the signal lines and provides better EMC behaviour.
KELLER devices operate at transmission speeds
< 250 kbps, so this function is not activated ex factory.
