Product Overview
The Tempo Communications NC-100 is a versatile digital wiring tester designed for professional use in telecommunications and data networking. This compact device accurately tests shielded twisted pair (STP), unshielded twisted pair (UTP), and coaxial cables, identifying common wiring faults such as shorts, opens, reversed polarity, crossed pairs, and split pairs. It also features a tone generator for efficient cable tracing and troubleshooting.

Setup and Initial Use
Before operating your NC-100 tester, ensure a 9V battery is correctly installed. The battery compartment is typically located on the rear of the device. Once the battery is in place, the unit is ready for use. The NC-100 is designed for straightforward operation, allowing technicians to quickly assess cable integrity.

Operating Instructions
Cable Testing
The NC-100 can test various cable types. For twisted pair cables (UTP/STP), connect one end of the cable to the RJ45 or RJ12 port on the main unit and the other end to the corresponding port on the removable remote test unit. For coaxial cables, use the F-Type female threaded connectors. The device will then display the wiring configuration and identify any faults.

Tone Generation for Tracing
To trace cables, the NC-100 generates three distinct, selectable digital tone patterns at 577 Hz and 983 Hz. Connect the tester to the cable you wish to trace. Use a compatible tone probe (not included) to locate the other end of the cable. The selectable cadences assist in distinguishing between multiple cables.

Maintenance
To ensure the longevity and accuracy of your NC-100 tester, keep it clean and free from dust and debris. Use a soft, dry cloth for cleaning. Avoid exposing the device to extreme temperatures or moisture. Replace the 9V battery promptly when the low battery indicator appears to maintain optimal performance. Some users have noted the device's durability over extended periods of use.
Troubleshooting
- Frequent Resets: If the unit resets unexpectedly, ensure the battery is fully charged and securely seated. A weak battery can cause erratic behavior.
- Inaccurate Readings/Test Fails: Verify that all cable connections are secure and properly seated in the RJ45, RJ12, or F-Type ports. Loose connections can lead to false readings.
- Tone Not Audible/Tone Test Aborted: Check the battery level. If Power over Ethernet (PoE) is present on the line, the tone test may be aborted (indicated by "more than 5V detected"). Disconnect PoE before attempting tone tracing.
- No Power: Check the 9V battery. Ensure it is new or fully charged and inserted with correct polarity.
