Terminating Impedance - ELGO Electronic EMAX2 Series Operation Manual

Terminating Impedance

As standard the interfaces CANopen, CAN BASIC ELGO (CN0) and RS422 are supplied with a termination
impedance of 120 Ω inside of the interface input. The termination impedance can be deactivated with the
S3 switch. The SSI interface is also supplied with an integrated termination impedance.
When using option V (encapsulated – IP65) the deactivation of the termination impedance has to be
specified by ordering as option A (without termination impedance).

Installation / Commissioning
In order to deactivate the termination
impedance switch S3 use micro-
