Controller LEDs

confocalDT 2421 / 2422

RS422

 - Differential signals according to EIA-422, electrically isolated 

from the supply voltage.

 - Receiver Rx with 120 Ohm internal terminating resistor.

  Terminate the transmitter input Tx on the evaluation unit (re-

ceiver) with 90 ... 120 Ohm.

  Use a shielded cable with twisted wires.  

Cable length less than 30 m.

  Connect the ground connections.

  The pin assignment for the 9-pin D-sub socket is not stan-

dardized.
