6. Applications

• Creating branch points in Modbus Plus/RS485 daisy‑chain networks

• Connecting multiple RJ45 devices (PLCs, HMIs, I/O) to a single trunk cable

• Extending networks without re‑wiring

• High‑noise industrial environments (EMI/RFI protection)

7. Installation Steps

1. Power off the entire communication network before installation.

2. Place the 170XTS04100 in a clean, dry location (free‑standing or DIN rail).

3. Identify the three ports: IN (main line), OUT 1 (next node), OUT 2 (branch).

4. Insert the main network RJ45 cable into the IN port.

5. Insert the next node cable into OUT 1.

6. Insert the branch cable into OUT 2.

7. Ensure all RJ45 clicks lock and shields (pins 7–8) are continuous.

8. Verify shield continuity with a multimeter (all ports shield‑to‑shield ≤ 20 mΩ).

9. Power on the network and test communication.

8. Maintenance

• Inspect RJ45 ports periodically for dirt, corrosion, or bent pins.

• Check shield continuity between all three ports.

• Avoid excessive cable bending near the connector.

• Replace if housing is cracked or contacts are damaged.

9. Safety Instructions

• Installation must be performed by qualified personnel.

• Disconnect all power before wiring or modifying the network.

• Do not expose to liquids, corrosive gases, or conductive dust.

• Use only with rated voltage and communication protocols.

10. Troubleshooting

• No communication:

  • Check RJ45 pinout (Data+/Data− alignment).

  • Verify shield connection (pins 7–8) across all ports.

  • Reseat connectors; check for bent pins.

• Intermittent errors:

  • Ensure all connections are tight and shields are continuous.

  • Reduce nearby EMI sources (motors, drives).

  • Confirm cable length adheres to Modbus Plus limits (max 500 m at 1 Mbps).
