Still wondering? JD I never found any. I just settled for the converters that plug into the onboard serial port and poke out about 2". The systems are all in use and haven't had any problems with them. It just doesn't look as polished as the ones I've see that have the slot type converter. Thanks.

Thanks for the replies. I've already got converters, i was just looking for one I could mount in the PC rather than screw onto the serial port. Doesn't look like Moxa carries anything like that. The one from Divis looks like it will work. I'll see if I can find those online. Thanks again.

Hi all. I've been building some PC based DVR systems using ildvr cards, and they work very well. I've seen some RS232 to RS485 converters on other systems that are actually a PC "card". Basically, the converter is built into the card, so the card doesn't plug into the motherboard at all. It just sits in a slot in the back of the PC. The "card" has a DB9 input, and a 2 wire +/- teminal block output. So you run a short DB9 cable from the serial port on the PC to the DB9 port on the "card". Then run a 2-wire cable from the +/- terminal block to your cameras. Has anyone seen these or know where I can get them? I've looked everywhere. I've been using just the little adapters you plug into your serial port, but i'd rather have something more professional/sturdy. Thanks, Phil
