sorry to kick this thread alive again..
but I find no other threads about SDS1102CML hack
new trick : i was not able to connect via putty, correct ip number, tribble checked it was corrent,
none of the mentionened ports, SSH or telnet, no way. also checked with nmap where they could be..
The solution : get siglent software EasyScopeX
this will connect to the scope just fine,
its command interface also accept the hack code, and you can up the bandwidth that way
