Dear Users,

I have got a strange problem for the symbol ap-5131. I bought this device from a second-hand vendor. I connected the device to my network system and run it.
but I could not find the device password. I cannot log into the device. I've tried all the username and passwords that I could find.

Is there something I can do about it?
I'll try to establish a computer connection with the rs232 cable. What commands do I use?
Which version of the java program should be installed on the computer that is logged in?

I sent a screenshot with an error message.
I would be very glad if anyone can help with the problem.

Best Regards

Huseyin Basbay

PS: I tried with java 6 update 45 on windows xp and java version 8 update 201 on windows 7. I couldn't login.
PS2: I contacted the second-hand vendor. he suggested standard username and  passwords. nothings changed..
