Issues Caused by Damaged Network Cables

In some cases, Easy POS users report issues such as:

• POS not syncing data with the back office
• POS data not uploading to the back office
• Changes made in the back office not appearing on the POS
• KOTs (Kitchen Order Tickets) not reaching the kitchen printer
• Tablet orders not syncing between tablets

While these problems may appear to be software or internet issues, they are sometimes caused by damaged network cables used in the POS setup.

Why Network Cables Matter

Many devices in your POS environment communicate through Ethernet network cables, including:

• KOT / BOT printers
• Receipt printers
• Routers and switches
• POS terminals

If the network cable connecting these devices is damaged, communication between devices may fail or become unstable.

Inside a Network Cable

A standard Ethernet cable (such as Cat5e or Cat6) contains:

• 8 small copper wires
• These wires are arranged as 4 twisted pairs

These wires work together to send and receive data between devices. They do not function as separate "upload" or "download" cables; instead, the pairs carry data both directions depending on the network technology.

Common Causes of Network Cable Damage

The small copper wires inside a network cable can become damaged due to several reasons:

• Rat or rodent bites
• Cable being crushed by heavy objects
• Frequent bending or pulling
• Improper cable installation
• Environmental damage

When these internal wires are damaged, the cable may still appear normal from the outside but data transmission becomes unstable or slow.

Signs of a Damaged Network Cable

You may experience the following symptoms:

• POS fails to sync with the back office
• Orders do not reach the kitchen printer
• Tablets do not sync orders with each other
• Devices disconnect randomly from the network
• Slow communication between POS devices

What You Should Check

If you experience any of the issues above, check the following:

1. Check Internet Speed

Ensure your internet service provider is delivering the expected download and upload speed.

1. Test the Network Cable

Even if your internet speed is good, your device may not receive the full speed due to a damaged network cable.

1. Inspect Physical Cable Condition

Look for:

• Visible cuts or bends in the cable
• Loose connectors
• Damaged RJ45 heads
• Signs of rodent damage

1. Replace the Cable

If you suspect damage, replace the network cable with a new one and test the system again.

Best Practice

To maintain a stable POS environment:

• Use high-quality Cat5e or Cat6 cables
• Avoid running cables where they can be crushed or bitten by rodents
• Periodically inspect network connections
• Replace damaged cables immediately
