Usage Instructions

Preparation: Ensure the host cabinet is powered off and properly grounded. Wear an anti-static wrist strap to protect the sensitive internal circuitry of the card.
Installation: Align the COZBU 103 card with the backplane connector in the EXLAN rack. Apply steady, even pressure to insert the card until the locking mechanism is engaged.
Connectivity: Connect the required communication cables (RS-232, RS-485, or specialized serial interface) to the front panel ports. Use shielded cabling to minimize signal interference.
Configuration: Access the EXLAN system engineering software to define the communication parameters, including baud rate, parity, and station addresses, to match your network setup.
Verification: Monitor the diagnostic LEDs on the card’s front panel to confirm link activity and data transfer status during the initial startup phase.

Frequently Asked Questions (Q&A)

Q: Is the 342/4 R1J compatible with all EXLAN rack types?

A: It is designed for specific EXLAN generations. Always verify the board revision matches the hardware requirements outlined in your original system documentation.

Q: What should I do if the “Comm Error” LED lights up?

A: First, verify the physical cable connections and ensure termination resistors are correct. If physical links are sound, check the software configuration settings for address conflicts or baud rate mismatches.

Q: Is this card hot-swappable?

A: No, it is strongly recommended to isolate power before installing or removing communication cards to avoid electrical spikes that could damage the backplane.
