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 re-
quires shielded 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.
Avoid Grounding in a Patch Panel
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 con-
nector 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.
