BLHX Error

If you power-up the BLHX and the LED starts counting from 0 to 9 continuously and you are unable to communicate with it via RS232 you may have a jumper set incorrectly. In addition to this, if the terminal is continuously spitting out a letter(our unit prints "U"), the controller jumper link #9 is probably set to A. Link #9 is a SelfTest for the controller card only.
