ReadyNAS Ultra6 stuck with ReadyNAS Logo - TTL Port does show strange data only
Hi, I have a broken ReadyNAS Ultra6 that I try to revive. I have still checked memory (tested in another PC), CMOS battery (measured with 3,15V) and PSU (exchanged). As all does not solved to get...
I believe the Ultra6 does have TTL output on the serial port, but TTL is 5V, not 3.3. You may be confusing "TTY" (the protocol, short for TeleTYpe) with "TTL" (a logic voltage level, short for Transistor-Transistor Logic). You should find one of the pins has the voltage on it, so a meter will let you know. The voltage, pin-out, and baud rates for the ReadyNAS serial ports are inconsistent between models until you get to the ones with the micro-USB type connection. At one time, there was a partial list of them either in this forum or pointed to here, but I've been unable to locate it for some time.
Jipie, I had to restore it with an Radiator 4.2 firmware which worked...but to know it the TTL question would be nice if answered.
Cheers,
Nils
