blinking output leds on powerup

[rhyoung]

I just got a t100md888.  I have little or no prior experience with controllers, and limited experience with electronics.  When I supply power, a small led between the power and rs485 connectors blinks together with outputs 1-4.  That is as far as it gets.  I can't find anything in the instructions about this led or anything that describes my blinking.  What is wrong?

The green LED between the power and the RS485 connector is the power LED. There is another 1 green and two red LEDs which are status LEDs. When you apply power to the PLC, the power LED should light up and stay there (not blinking). The 3 status LEDs will be turned ON for 1 second, and then goes off. This is just an indicator that the PLC has completed self-test and has loaded the program from the EEPROM and is ready to run. If you have an MX-RTC, the green status LED will be turned OFF, but if you don't, then the green status LED will stays ON. These have been stated in the installation guide.

If you have further queries, please call our technical support line at (408)-359-2008 on weekday and we can guide you through the setup process to communicate with the PLC.

they blink, and the 3 status leds don't do anything.

thanks to Leon for the phone call.  You were very helpful, and at least now I know I fried my board.  I will try not to do it again.
