DMP 4400 rs232 connection with samsung 40" lcd

[carlos_canepa_2]

Hi, i´m testing the dmp with an lcd from samsung. I´m using the rs-232 port just to turn on and  off the monitor.

I have same questions:

1- wich rs-232 cable should be used straight? null-modem? The documents i checked do not mention that.

2- I was testing it with my pc first instead of the dmp, 9.6k 8n1 no flow control, with no sucess.

3- Hexa commands for Samsung lcd, there is a table?

Thanks for any lead.

Regards

Carlos

I believe it is a null modem cable.  That has worked for me.  I have attached a PDF that I found that describes how to create RS232 hex commands for Samsung displays.  I have tried a few from this list and they worked for me.

I also Used an RS232-cross cable and work for me.
