madkad Posted December 28, 2008 Share Posted December 28, 2008 Hi looking throught my Xvision TDVR4 manual I see I can control it by my computer through the RS485 Port on the back, but it doesnt seem to tell me any more infomation about it, I see also that there is only a + and _ for the RS485 port ther looks like the rest next to them are for the alarm settings. Can any one help me on what I need to be able to do this, can I do it via USB or is it something else? Thanks Link to comment Share on other sites More sharing options...

madkad Posted December 28, 2008 Author Share Posted December 28, 2008 could I not use a RS232 to RS485 converter? or a USB to RS485 converter? but even if I could there isnt a socket in the back of my DVR there seems to be only a section like the alarm section saying RS485 with - and + sockets so how would it work?

madkad Posted December 28, 2008 Author Share Posted December 28, 2008 the DVR also has a LAN socket on for going to a router, I was going to do that but I was woundering what about going straght to my pc from lan to lan, can that be done do you know? if it can I wouldnt have to use the RS484 idea Link to comment Share on other sites More sharing options...

luggsey Posted December 29, 2008 Share Posted December 29, 2008 any one?I know I ask alot of questions sorry Yes use the LAN connection, the DVR will have it's own URL which normally allows download of the viewer software, it may have to be downloaded from the web...you can then view the DVR remotely if the DVR can do it. Cable, try a standard cat 5 patch cable as I have been told on this board that most LAN devices will now talk to each other on a standard cable, however a 'crossover' cable would be my choice, or just get a router? ----------------------------------------------------------------------------------------------------------------------------------- Life is like a box of chocolates, some bugger always gets the nice ones!

james.wilson Posted December 29, 2008 Share Posted December 29, 2008 if those ports are indded for remote control (and not camera control) then yes a 232 - 485 converter will work from a hardware point of view. But you will need the protocol or some software to send the commands securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.

Thanks Ay up Madkad, Please don't take this the wrong way but, I just wonder if you've the right end of the stick whilst reading the manual. I'd only expect to connect a DVR these days to a PC using Ethernet. PC to PC should be crossover, unless you've auto-sensing port on your PC. I'd only expect to use the RS485 port on a DVR to send telemetry. If indeed I'm wrong, you'll need as Redbull says, a configurable protocol converter such as the KK, together with protocol driven software application on your PC. I went up into the attic...I found a Stradavarius & a Picasso. Unfortunately..... Stradavarius couldn't paint, and Picasso made a shocking fiddle.

Hi, well at the start I was going to use the port idea as i dont have a remote for my system, but then I found out about the lan and started thinking if I can just use my software to do the same stuff I would have done with the port, but more like backup stuff so the lan idea would be better. I have tried putting a lan cable in and to my pc but my pc doesnt seem to want to conect if any one here knows much about doing this i would be very greatfull on some tips in some way thanks Link to comment Share on other sites More sharing options...

Do a web search for the instructions and software, you will need to know the URL of the DVR (It's IP number) which should be standard. ----------------------------------------------------------------------------------------------------------------------------------- Life is like a box of chocolates, some bugger always gets the nice ones!
