  • Page 41: Troubleshooting

    Setting Up External Communications Troubleshooting Problem Cannot establish communication between ACT2 controller and Maestro software. Possible Causes and Solutions • Observe the TX and RX LEDs on each ACT2 controller board (see Figure 26). If no flickering is seen, the modem is not communicating with the ACT2 controller.
  • Page 42 Communications • If flickering of the TX and RX LEDs on the ACT2 controller are observed, check the modem for similar flickering TX and RX LEDs. If the modem LEDs are not flickering, check the modem for proper connections. • Ensure that all ACT2 controllers have been assigned a unique communication ID (see the Programming ACT2 System Parameters Technical Bulletin for more information).
