Smart max Wireless Card Sharing

Just a cheap card splitter!...

Can't say whether that type work or not though, not come across them before..

There usually much more expensive....

I have purchased the smartmax wireless cards and the wireded cards and have discovered that the wired cards works BUT the updating between the decoders is very slow and had to constantily reset the decoder or remove and reinsert the cards and this has caused the wired cards to loose there firmware which does not come with the cards and no instruction or links to reflash them.
The Wirless cards work much better with only a second delay update which causes the one decoder to say finding smart card maybe once a day BUT this unit only works with 2 cards the 3rd card stops the 2nd card working if it works and the id numbers are different on all cards, It looks like the master only comms to 1 card at a time.
If anybody has info or software to reflash or reprogram any cards please help THANKS
