Installation and Wiring Guide

5.1 DIN rail installation

Installation: Hang the module from top to bottom onto the NS 35 DIN rail, ensuring that the upper fixing claws hook onto the upper edge of the rail; Then push the module towards the installation surface until you hear a "click" sound, indicating it is tightened. After installation, check for firmness.

Disassembly: Use a suitable tool (such as a screwdriver) to insert the locking claw and pull it down; At the same time, pull the module out slightly and then lift it up to remove it.

End clamp: It is recommended to install universal end clamps (E/NS 35 N, order number 0800886) on both sides of the module to prevent the module from sliding on the guide rail.

5.2 Power Wiring

Use 0.2 Connect a 2.5 mm ² wire to the power terminal (note polarity:+24V and 0V).

It is recommended to connect the DIN rail to the protective earth (PE) through the grounding terminal, as the module housing is grounded through the rail.

The torque for tightening the screw is 0.5 .. 0.6 Nm。

5.3 Ethernet cable connection

Insert the standard RJ45 plug into the front panel port. Due to the support for automatic crossover, there is no need to worry about straight or crossover lines.

Gently pull the cable to confirm a secure connection.

5.4 Fiber optic cable connection

Cleaning: Before connecting, ensure that the fiber optic plug is clean, and specialized cleaning tools can be used.

Alignment: Align the SC or ST connector correctly (pay attention to the positioning key) and insert it into the fiber port. For SC duplex connectors, it is usually necessary to ensure that the transmit (Tx) and receive (Rx) channels are cross connected with the other end (i.e. the local Tx is connected to the opposite Rx).

Fixed: For ST connectors, lock them by rotating a quarter turn after insertion; For SC connectors, simply push them in and the buckle will automatically lock.

Attention: Strictly follow the fiber manufacturer's minimum bending radius, maximum tensile force and other parameters to avoid signal attenuation or fiber breakage.

Detailed explanation of configuration and diagnosis

6.1 Basic configuration steps

Check the DIP switch settings (usually all bits are set to OFF by factory default).

Connect the power and observe if the US LED is constantly on.

Connect the RJ45 cable and observe whether the LNK/ACT and 10/100 LED are indicating the link and speed normally.

Connect the fiber optic cable and check if the other end device can establish a link. If the link is not working, try enabling DIP 1 (LFPT) or checking the fiber optic cross connection.

6.2 Typical Configuration Scenarios

Scenario 1: Connecting to a standard switch: Set DIP 2 to OFF (self negotiating), and the converter will automatically negotiate 100M full duplex with the switch. This is the most commonly used configuration.

Scenario 2: Connecting an old 10M device: Set DIP 2 to ON (forced mode), DIP 3 to ON (10Mbps), and DIP 4 to OFF (full duplex) or ON (half duplex) as needed.

Scenario 3: Enable Global Link Diagnosis: When using two FL MC 1000s connected back-to-back via fiber optic, set DIP 1 on both devices to ON. This way, any link failure on either side will cause both electrical ports to shut down simultaneously, notifying the terminal device.

6.3 Troubleshooting

Possible causes and solutions for the fault phenomenon

The US LED does not light up. The power supply is not connected or the voltage is too low. Check the power supply wiring and voltage (>12V is required)

LNK/ACT does not light up, RJ45 link not established. Check if the network cable is intact and if the other end device is powered on. Try replacing the crossover/straight line

Ensure Tx Rx cross connection due to fiber link failure, incorrect fiber connection or excessive attenuation; Clean the fiber optic end face; Check the bending radius; Calculate optical power budget

Check DIP 2-4 settings for low communication rate, duplex mismatch, or interference to ensure consistent self negotiation or forced settings at both ends; Check the quality of the network cable
