FAQ

Q: What is the maximum cable length for the RS-485 interface?
A: RS-485 supports cable lengths up to 1200 meters depending on baud rate and cable quality.

Q: Can the RS-422 and RS-485 interfaces operate simultaneously?
A: Yes, both interfaces can be active simultaneously, connecting to different devices or networks.

Installation Guide

1. Power down the FSC Central Part rack.
2. Remove system bus jumper before installing the ECM.
3. Insert the module into the Central Part slot.
4. Connect RS-422 cable to Top Interface (A).
5. Connect RS-485/RS-422 network to Bottom Interface (B).
6. Configure baud rate and protocol via FSC software.

Selection Tips

• For dual isolated RS-485/RS-422, use 10024/I/I.
• For RS-422 + RS-232C, use 10024/H/F.
• Ensure proper RS-485 termination for network stability.
