Hey guys I am trying to interconnect my two HAI Omnipros with a Cat 5 cable utilizing the RS232 extender from Monopric found here: http://www.monoprice.com/products/product.asp?c_id=101&cp_id=10105&cs_id=1010503&p_id=3598&seq=1&format=2
I can't seem to get it to work. I confirmed the cable tested properly. The kink is that I need to make db9 to rj45 connections for the omnipros. I replicated their design (I believe properly) from their kit that is used to control the russound and other serial devices. The one other issue is that I am using TWO of their reverse order cables (phone style literally reverse order on one side). So I believe I am undoing that RX to TX when using two of them. So I reversed pins on my DB9 to RJ45 connector and tried it but alas it does not work. I have tried about 20 different combinations of DB9 to RJ45 configurations thinking this was my problem but I have no idea. I believe my programming is proper. I see the one unit blink on its transmit light when I send the command but that is all I get.
So I don't know if the Rs232 unit is on or works (there are no lights indicating anything) and one reviewer on their site mentioned he had to short points 6 and 7 so he could get a proper handshake. I don't know if that was the extender or device specific. Not knowing what to do I tried it but still not any better.
Any suggestions or troubleshooting ideas would be GREATLY appreciated!
Thanks,
Neil
