If the powerup self-test detected anything wrong, the four LEDs
illuminate in different patterns, telling you what the self-test found. In
general, if one or more front panel indicators is blinking after the self-test,
there may be a faulty circuit board in the programmer. Contact your
nearest Data I/O Customer Support office for more information. The
different combinations of blinking LEDs are explained below.
Note: X = don’t care condition.
“Terminal port OK” means that the programmer has detected an RS-232
serial device connected to the Terminal port and that a valid connection
has been established with that device.
Are the Right LEDs Lit? If the programmer completed the self-test successfully, the Power LED
will be lit. Also, if you have equipment connected to the Terminal and
Remote ports, the corresponding LEDs should be lit. Figure 2-6 shows the
front panel indicators.
