Recovery: Load and Setting Defaults
For cases when the configuration string, power on
string or reset string causes the KeyAT-5 to become
inaccessible, two recovery methods are available:
Send RS-232 Break on Power-up: If you send a
break condition (type Alt-B ten times using Tera
Term) to the RS-232 port when applying power,
the KeyAT-5 will start with default configuration
settings. Configuration, Power On, and Reset
Strings will not be changed. The message
“Loading Defaults…” will be sent to the RS-232
Port.
Keyboard 20 Consecutive Num-Locks: Typing 20
Num-Lock keys consecutively, causing the Num-
Lock LED to tun on and off 10 times, will cause
the KeyAT-5 to load the default configuration
string, and the Power On and Reset strings will
be cleared. When this occurs, all the keyboard
indicators will light for a second, and the
message “Setting Defaults…” will be sent to the
RS-232 Port.
