-Sufficient power is available from the 12V terminals of the interface for LX terminals P+ and P- (power). Connect the DATA wires to T+ and T- (tower). If the data cable length drops the supply voltage, use a booster power suppply on the 12VDC input of the LX.
+Sufficient power is available from the 12V terminals of the interface to operate the LX control panel. If the data cable length causes the supply voltage to drop so that the LX control panel does not operate, try the following remedies.
+* Use additional spare wires in the data cable to carry more current.
+* Plug a booster power suppply into the 12VDC input of the control panel.
