Dear Mr SunWoon I'sm so sorry, the letter previous i said not clear about my problem. The LED 4CH is RUNLED (Status of EZL-410 LED Active Low), when power supply 3.3v was provided EZL-410 and then it blind, i dont understand when it was blinked light that is normall or abnormal? And the same with EZL-50L, when power supply 5V was provided, The LED status of EZL-50L was also blinked light. So, can you show me know about two case above is normal or abnormal? IF THEY HAS FAIL, WHERE CAN I BUY THEM AT VIETNAM? or can you give me address that can buy them? and price of them? Hearing from you soon!
