Symptom/action troubleshooting

Table 14 provides a list of symptoms that indicate a problem in the Tracker system. For each symptom, the table provides one or more actions that you can perform in an attempt to resolve the problem.

Tracker controller does not	• Verify that the telephone cable is connected to the PC modem port (Figure 24 on
communicate by modem.	page 48).
	• Verify that the phone line is an analog line (not digital).
	• Perform the modem self-test procedure from the display module.
	Note: The modem is an integral component of the main module and is not field replaceable.
	Replacement of the modem requires replacement of the main module.

	• Verify that the PC workstation is using the Tracker controller software; other com-
	munications software will not work.
	• Look for activity on the PC RX LED (Figure 30 on page 56).

	communication link.
	After the controller has built its database after the initial power up, the controller no
	longer automatically discovers UCMs. If you want to initiate the discovery process,
	you must do so manually. Initiate the discovery process when a new UCM is added
	to the system or an existing UCM is replaced.
	• Verify proper wiring of the Comm5 communication link. (UCMs can be discov-
	ered only if Comm5 communication has been established.)
	• Wait at least 5 minutes for the controller to discover the UCMs.
	Note: You can press the service pin button on a UCM at any time to check if it is communicating
	with the controller. Pressing the service pin button causes the UCM status LED to flash on and off
	(known as “winking”), if the controller is communicating with that UCM.
