Electrical noise on twinaxial cables that are not installed correctly may affect the twinaxial workstation I/O processor card.

Examples of this include open shields on twinaxial cables, and station protectors that are not being installed where necessary.

Check for the following on the system:

• There must be no more than 11 connector breaks in a twinaxial cable run.
• Station protectors must be installed (in pairs) where a cable enters or leaves a building.
• There can only be two station protectors for each twinaxial run.
• There is a maximum of seven devices (with addresses 0-6) for each cable run.
• There is a maximum cable length of 1524 meters (5000 feet) for each port.
• All cable runs must be ended (terminated).
• Disconnect all twinaxial cables that are not used.
• Remove any cause of electrical noise in the twinaxial cables.
• All workstations must be grounded.

This ends the procedure.
