No. 451	Re: Level converting circuit	2008-02-19

Hello, This is Sollae Systems. I'm sorry i can't help you right now. Because, the engineer is on a business trip who he is in charge Hardware. I just can tell you some check points. 1. You have to remove a CF-CARD before turn on the EZL-80C. 2. The EZL-80C use 115200bps, 8 data bits, 1 stop bit and no flow control for ezSerialConfig. 3. The EZL-80C sends below message when it starts with serial configuration mode. 700 EZL-80/AVR64 SCFG v1.0 Sollae Systems So, you'd better check above message with RS-232 terminal program(ex : hyper terminal) or an oscilloscope. Thank you. > vin wrote: > ~~~~~~~~~~~~~~~~~~~~~~~~~~~ > I need the level converting circuit in order to connect my EZL-80c and configure it. I tried but got an error "No response from ezTcp". I use the ICL3232 for converting the RS232 but it didn't work. help me with this ICL3232 in making a level converting circuit. > thx
