The site you listed for a RS232 opto in not working... Just where can I get a "opto" unit? Is there a schematic for a unit? I can build one from that! Thanks, Chuck Alldrin Chico, CA |

http://www.bb-elec.com/product_family.asp?FamilyId=1 9POP4 is what you need, don't forget you need a power adapter as well As for a do it yourself circuit, the Suntie is a single TX line, if your into electronics, you could for a few bucks make a simple isolator, most folks find the bb unit worth the price of not going this route |

Thanks for the quick reply I have 2 units that are about 150' apart. I will need 2 opto's correct? Do you assign each to different serial port number? How can you display both at the same time on the screen? RE: schematic.. I can buy opto's for less than $1 each..is there a schematic for a simple unit? Thanks, Chuck Alldrin |
