Hi Guys, 
  
I am new to the forum and relatively new to security camera installs so please bear with me  
  
We recently purchased some "Capture" SDR-401 DVRs and some new model Capture FTD450 PTZ cameras for a client. 
  
The DVR has a RS232 port for PTZ control so I am using a Startech IC485 RS232-RS485 adaptor to connect to the cameras.  This converter has a fair bit of options (DCE, DTE, mode) but I beleive I have set it up right, DCE and for half duplex (as it is a one way communications). 
  
I have gone through DVR menu and set the RS232 port to PTZ use, 9600baud, 8 bit/1stop bit, no parity and the camera DVR option to Fastrax-2.  On the camera end, this is where the newbie factor comes in, I didnt get a controller keyboard so all I can do is play with the dip switches.  On those I setup Fastrax-2, 9600 baud and id to 1 (same on DVR). 
  
I can not seem to get the DVR to provide TPZ control to the camera.  I have one setup on the bench and the other at the client location (via ferry, pain) so I am sure it is not faulty equipment.  I also tried a TPZ controller on my PC and that didnt work.  I have tried different baud rates and protocals with no difference. 
  
I suspect that either there is an option on the camera that I cant access without the keyboard, it wont work without a keyboard (unlikley) or there is an issue with my DB9 to DB25 cable/RS232-RS485 converter setup.   
  
Any ideas where I can look next or trouble shoot?  I might take the whole thing back to the dealer and tell them to make it work for me but thats a bit hard with half the equipment a ferry away haha.
