smarty 0 Posted December 30, 2005 Geovision automation question: I have a Geo 1240 card in a HP computer with only 3 PCI slots. The slots are now filled (Geo board, Video Card, and cheap PCI modem). I want to have the Geo-1240 control exterior flood lights based on camera motion etc. I guess I will need a Geo I/O box (external ??) and an external Geo RELAY box. The hard part is that my damn (new) computer does NOT have a serial port output. And, internal mounting of another card would be tight (I could throw out the internal modem and use an external). Would a USB to serial converter feed the external Geo I/O box? This box then controls the external relay box (right?). Please advise. Share this post Link to post Share on other sites
Thomas 0 Posted December 30, 2005 Ditch the internal modem and go with an external modem. You'll be happier. Share this post Link to post Share on other sites
CCTVDude 0 Posted December 30, 2005 Can you free up a slot by switching to an AGP Vid card or is it an older mother board? Definately an external modem would help... Share this post Link to post Share on other sites
smarty 0 Posted December 31, 2005 It is a BRAND NEW board. It only had 3 slots for expansion (all PCI). It has a lot of USB (2.0), fire wire and other connection options (I guess serial ports are kinda "old news" with respect to connecting periperials to computers these days). I have no problem with getting rid of the internal modem. That would free up 1 PCI slot. Anyway, I guess my main question is how to connect the 10 amp relay box to the PC. Using just the I/O box/card will not work for 120 VAC type devices (right???). Share this post Link to post Share on other sites
RDeSmet 0 Posted January 4, 2006 Do you still have expansion slots on the back of your case?? If you use a Geovision Net I/O card, you don't need an actual pci slot from your motherboard, you just need a free mounting slot on the back of your case, the Net I/O card hooks into your Geovision Capture card via a ribbon cable. If you don't have any expansion slots on the back of your pc case, then you can control the External GV-Net box with a usb to serial adapter. But then you need to also add a GV I/O since the GV-net is just a rs232 to Rs485 converter. Share this post Link to post Share on other sites
iwatchlive 0 Posted January 4, 2006 I have no idea how to connect it I would love for someone to explain how this get's done. We have plenty of access control jobs which make it look simple with stand alone access control devices. Where can I get the ribbon cable if my GV-!) and Relay didn't come with it? Thanks for any input! Happy New Year! ADAM! Share this post Link to post Share on other sites
