Product Description

The Longshine LCS-883C-TB is a legacy industrial-grade Fast Ethernet Switch (often referred to as a “Bridge” in older documentation) designed to provide reliable networking in environments requiring both twisted-pair copper and BNC (Coaxial) connectivity. It is particularly known for its “Combo” design, bridging the gap between modern RJ45 cabling and older Thinnet (10Base2) networks.

Product Parameters

Key Product Advantages

• Hybrid Connectivity: The inclusion of a BNC port allows users to maintain older coaxial cable runs without replacing the entire infrastructure, while still utilizing high-speed RJ45 for newer devices.

• Auto-Negotiation: All RJ45 ports support NWay auto-negotiation, automatically determining the best speed (10/100 Mbps) and duplex mode (Half/Full).

• Robust Design: Longshine’s industrial heritage ensures the LCS series handles electrical noise and varied temperatures better than standard consumer-grade office switches.

• Plug-and-Play: No software configuration is required. The switch automatically learns MAC addresses and builds its routing table.

• Collision Detection: Specific LED monitoring for the BNC port helps troubleshoot common coaxial network issues like improper termination.

Product Applications

• Legacy Industrial Integration: Connecting modern PLCs or industrial PCs to an existing older factory backbone that uses BNC coaxial cabling.

• Marine & Aviation: Used in older vessels or aircraft where BNC cabling was preferred for its shielding and physical locking mechanism.

• Lab Environments: Testing and maintaining older computing hardware that lacks Ethernet RJ45 ports but features integrated BNC interfaces.

• Small Business Expansion: Cost-effective way to bridge two separate office wings where one is already wired with Coax.

Important Usage Notes (Precautions)

• BNC Termination: The BNC port must be properly terminated. If the LCS-883C-TB is at the end of a coaxial run, a 50-ohm terminator must be used on the T-connector. Without it, the entire BNC segment will fail due to signal reflection.

• Speed Limitation: Note that the BNC port is strictly 10 Mbps. While the RJ45 ports can handle 100 Mbps, any data passing through the BNC segment will be throttled to 10 Mbps.

• Power Polarity: When using a replacement power adapter, strictly verify the voltage and polarity (center positive/negative) as indicated on the device label to avoid frying the internal capacitors.

• Environment: Avoid placing the switch in unventilated areas. Despite its industrial build, excessive heat can lead to “packet dropping” or port hanging.

Port Layout Overview

• Ports 1-8: Standard RJ45 for Cat5/Cat5e cabling.

• BNC Port: Located on the rear or side, intended for RG-58 coaxial cable.

• Uplink: Typically, one of the RJ45 ports serves as a MDI/MDI-X port (often via a push-button or dedicated port) for connecting to another switch.
