4. RJ45 Pinout (Termination Internal Wiring)

• Pin 1–2 (Data+) ↔ 150 Ω ↔ Pin 3–6 (Data−)

• Pin 4–5: GND (no connection inside plug)

• Pin 7–8: Shield (connected to metal shell)

5. Key Features

• Precise 150 Ω termination: Matches MB+/RS485 characteristic impedance

• Fully shielded: Reduces EMI/RFI at line ends

• Plug‑and‑play: No power, no configuration

• Compact & lightweight: Fits tight cabinet spaces

• Interoperable: Works with 170XTS04100 (T‑connectors) and all MB+/RS485 RJ45 devices

6. Applications

• End‑of‑line termination in Modbus Plus/RS485 daisy‑chain networks

• Install at the last RJ45 port of the farthest PLC, HMI, or I/O node

• Required for 1 Mbps Modbus Plus to avoid data corruption

• High‑noise industrial environments (shielded termination)

7. Installation Steps

1. Power off the network before installation.

2. Locate the last physical node in the daisy‑chain.

3. Insert the 170XTS04200 RJ45 male into the unused RJ45 port of the last device.

4. Ensure the connector clicks and the shield (pins 7–8) makes full contact.

5. Only one terminator per bus segment (at the far end).

6. Power on the network and verify communication.

8. Maintenance

• Inspect for dirt, bent pins, or damaged shield.

• Check continuity: 150 Ω between pins 1–2 and 3–6.

• Replace if housing cracked or resistance out of spec.

9. Safety Instructions

• Install by qualified personnel.

• Disconnect power before wiring.

• Avoid liquids, corrosive gases, conductive dust.

10. Troubleshooting

• Intermittent communication / high error rate:

  • Missing or incorrect termination (install 170XTS04200 at last node)

  • Two terminators installed (remove one)

  • Shield not continuous (check pin 7–8 contact)

• No communication:

  • Check pinout (Data+ / Data− not reversed)

  • Verify 150 Ω resistance with multimeter
