Pin assignment for easyNet [t-head3-np]

PIN 1; ECAN_H; Data conductor; conductor pair A

PIN 2; ECAN_L; Data conductor; conductor pair A

PIN 3; GND; ground conductor; conductor pair B

PIN 4; SEL_IN; Select conductor; conductor pair B

Assembly of the network cable for easyNet [t-head3-col]

The characteristic impedance of the cable must be 120 Ω.

The network cable does not require a screen braid.

If a network cable with shield braid is used, the braid does not have to be connected to PE. If a PE connection is required nevertheless, the screen braid must be connected to PE at only one end.

Note
Cable lengths and cross-sections  table.


The minimum operation with easyNet functions with cables ECAN_H, ECAN_L, GND. The SEL_IN cable is used only for automatic addressing.

Bus terminating resistor [t-head3]

A bus terminal resistor must be connected to the physically first and last device in the network:

  • Rating of the bus terminal resistor 124 Ω,
  • connect to PIN 1 and PIN 2 of the RJ-45 plug,
  • connection plug : EASY-NT-R.
