Troubleshooting
If there is no communication, check the following:
• Check the ethernet cable. Cable length must not exceed 150 ft. (45 m) for CAT-5E or 300 ft. (90 m) for CAT-6.
• If the cable was manually made, check continuity across each of the wires.
If there is intermittent communication, check the following:
• Check the ethernet cable. Cable length must not exceed 150 ft. (45 m) for CAT-5E or 300 ft. (90 m) for CAT-6.
