1.3. XTR DESCRIPTION

6. The XTR has 8 x green LEDs on Top. 4 x LEDS show the status of power supplies in the XRT;
The +12V, - 12V and +5V LEDs light up when the XTR has power.
•
The TOOL LED will not light up unless the XRT is supplying power to the XEM tool or individual
•
probe. When the XEM tool is NOT physically connected to the XTR, it can only be powered by
the batteries. When the XEM tool is physically connected to the XTR you can supply power to
the XEM Tool with the XTR, thereby saving battery life.
The TX + and TX – LEDs alternate between ON and OFF as the hardware receives the raw
•
signal from the tool, this indicates the XTR is receiving signal from the XEM tool.
The EM LOAD LED and DEPASSIVATE LED are no longer in use.
•
7. The XTR has the following ports on the left
Laptop: Provides power and data from the XTR to the XRT.
•
WITS: Provides serial communication with WITS protocol to other devices.
•
120V AC: Provides 120V to the XTR through an AC Power cord. (Some of the XTRs in the fleet
•
are equipped with hardware to take in power from 220V supply; if the XTR is not designed to
utilize 220V it will damage the hardware and will need to be returned to the repair center.
o The power requirement of the XTR can be identified as follows:
