LTC HOW-TO:
using Calibration Mode

To power down a Toro Network LTC system, flip the black circuit breaker on the Power Supply inside the cabinet to the "Off" position.

Calibration Mode is used for testing/troubleshooting/pinpointing issues within the communication system. Follow the steps below to use Calibration Mode on any Network LTC satellite:

  1. Power down the cabinet.
  2. While powering the cabinet back up, press and hold the left-arrow button on the Timing Mechanism. Continue to hold down the button until you hear the second series of rapid beeps.
  3. The satellite will then go into Calibration Mode. Once in Calibration mode, pressing "ENTER" on the Timing Mechanism will send a tone out from the Modem through the communication path (to stop the tone, press the down-arrow button).
  4. When the tone is on, the lights on the Modem come on, and the tone can be measured at the green signal connector on the Modem, at either of the outside pins (there are three pins in total). The measurement should read approximately 2 to 2.5V AC.
  5. To troubleshoot field communication wiring, keep this tone on and move to the next satellite location on the same communication path. At the new location, measure the signal on the Modem, just like you did on the original location. A significant drop in V AC indicates that there is a problem in the field wiring between these two satellite locations. However, you should note that the measurement normally somewhat diminishes if you are far away from the original location.

  6. NOTE: if there are any satellites on the communication path located between the original location and the new test location, the signal will diminish even further, making troubleshooting more challenging. Therefore, for the best testing results, continually change the original location so that you are always testing communication between adjacent satellites along the communication path.

    The process of ending Calibration Mode is different depending on your version of Network LTC:
