Hi,
It's there. Make sure you have the latest firmware version and have Json-RPC enabled in the first place:
Once you've done that go to your preferred software and authenticate with these parameters.
You must use "admin" instead of "root" and then instead of Admin01 use your password.
Everything else is by default the same as in RUT9XX.
{
"jsonrpc":"2.0", "id":1, "method":"call", "params":
[
"00000000000000000000000000000000", "session", "login",
{
"username":"admin", "password":"admin01"
}
]
}
