If the test routine fails, the LNK LED flashes. Refer to Chapter 15 , for more information on self-tests and error codes. If you have a communication program loaded and active (connected to the same serial port as the TA128), you should see the DTR LED should be ON after the self test. 9

Once you have completed all of the installation steps above, flip the
TA128’s On/Off switch to the ON (up) position.
The unit should cycle through a self test sequence, where you
should see a series of LED lights blinking (LED, B1, B2, AA). After
this cycle is complete, the PWR light should stay on.
If the test routine fails, the LNK LED flashes. Refer to Chapter 15 ,
for more information on self-tests and error codes.
If you have a communication program loaded and active
(connected to the same serial port as the TA128), you should see
