Hi all I'm really hoping someone can hepl me ou with this one, I recently inherited a used Kalatel DVMR Triplex unit (16 cameras), I know they are getting on a bit and this one works(records and plays back from unit), however I am having great difficulty connecting the Wavelet software on my computer to it, i've connected the 2 with a crossover ethernet and in details for the ip(10.2.8.202) . Also the network details in XP tell me i have limited or no connectivity Is there something i'm missing?
