Re: Pinout serial for RAP-155P

Well if you did not have a TTL-adapter for 3.3v and instead tried with only a normal Serial RS232 (as is the standard for the RJ45 on Aruba, HP, Cisco and so on) you have more than likely fried the serial port on your AP unless Aruba did a really good job protecting it. The TTL used on the ap port is at 3.3v while normal RS232 operates at 15v.

The adapter cable converts between TTL signal levels (AP side) and RS232 signals (console side) and draws power from the AP.
