Installation Best Practices

Follow these guidelines for the most reliable installation.
Continuity of Shielding
Shielding must be consistent through the DCS-LAN chain. Any cable or patch panel used for DIS components requires shield-
ed RJ45 connectors. All DIS components feature shielded RJ45 female connectors.
Avoiding Accidental Grounding (Galvanic Isolation)
Avoid accidentally grounding the DCS-LAN signal with the chassis ground of a patch panel. The DCS-LAN uses the shield as a
signal ground reference and cannot contact another ground anywhere in the connection.
To avoid ground issues:
• Plastic frames in patch panel: this ensures that the female JR45 connectors do not ground to the chassis of the patch
panel.
• Blank space between connectors: leave a space between each female RJ45 connector in a patch panel.
• Shielding continuity: each component in the chain must be shielded properly.
Note: The female connectors in all DIS components units feature an air gap that isolates the chassis of the connector and the chassis of the unit preventing
any galvanic (physical and thus electrical) connection.
Properly Securing Cables
As with any cable carrying a signal, use care when installing the equipment.
