EnDat
You can configure the TJ2-KS02 to interface directly to EnDat absolute
encoders. EnDat absolute encoders respond on a dedicated Clock and Data
1 MHz RS485 serial interface when their position is requested by the
controller. When you set the encoder to the relevant encoder mode, the axis
transmits an information request to the encoder on a fixed 250
μ
s cycle.
The connections for EnDat are:

Note
The TJ2-KS02 does not have a termination inside. In case of long
distances or disturbed communication, add an external termination
to the TJ2-KS02.
