Can 120 ohm bus terminating resistor be switched off?
Question:
When using system module 2173IB with the associated system cable a bus terminating resistor is fitted as standard. How can the resistor be removed if necessary?
Answer:
The bus terminating resistor (120 ohm) is not inside system bus module 2173 IB but is integrated into the Sub-D connector on the system cable. It is possible to use a different cable or modify the Sub-D connector (remove the resistor).
