nr509 & WEP 128bit

my WEP is 13 hx pairs - 128bit. there doesnt seem to be enough space to enter all 26 characters manually into the reciever. what formats does the reciever support? how do enter this key?

Hi maurybeck,
You will have to get some kind of hex to wep convertion utility for that to work. Please contact the manufacturer of your router. Thank you!

is any documentation available on which wireless security formats are supported for the NR-509?

Hi maurybeck,
All the network information can be found on page 49 of your owners manual. If you do not have an owners manual you can download one on our website. To find out how please view our blog post: http://onkyousacustomersupportblog.wordpress.com/2011/09/13/owner%e2%80%99s-manuals/
Thanks again for contacting product support!
