• Mounting: Any 2 consecutive slots, hot‑swap

• LED Indicators (Front):

  • PWR (Green) – Power OK

  • RUN (Green) – Module operational

  • COM (Green Blink) – RIO network activity

  • ERR (Red) – Comm fault / config error / duplicate drop address

6. Wiring & Pinout (BNC)

• Center: Data (RIO signal)

• Shield: Ground (PE)

• Termination: 75 Ω at head (CRP93100) and last drop (CRA931/932)

• Shield grounding: Ground at one end only to avoid ground loops

7. Software Configuration

• Unity Pro (recommended)

• Concept v2.2+

• Modsoft v2.32+

1. Add 140CRP93100 (2 slots) to I/O configuration.

2. Enable S908 RIO master function.

3. Set drop addresses: 1 … 31

4. Map remote I/O (%I, %Q, %MW) to Quantum memory.

5. Download configuration to CPU.

8. Troubleshooting

• PWR OFF: Check 24 VDC backplane; reseat module.

• RUN OFF: Missing/invalid config; re‑download project.

• ERR ON: Wrong termination, cable short, duplicate drop address, or baud mismatch.

• COM no blink: No drops on bus; check cabling/termination.
