OPERATING MODES

c) By the attached keyboard
By executing a ‘hot-key-sequence', the system is shifted into a command mode. Now CPUs
can be selected from the attached keyboard. Access to a switch in the second level (slave) is
also possible. To show that the command mode is active, all three status LED on the
keyboard flash rapidly. Press <ESC> to exit the command mode.
User commands
The input of letters does not differentiate between large and
lower case.
<SHIFT> shifts between upper and lower case.
<Key1>+<Key2>+ … means that all keys must be pressed at
the same time
<Key1>, <Key2>, … means that the keys must be pressed
successively
The device is designed to work at up to two levels. In command mode, all commands are sent
to the master and/ or the only device. For further extensions, input the port number prefixed
with a “0”.
For fast switching within one level (master level / slave level) the direct selection of a port is
possible by simultaneously pressing <SHIFT>+<Port-No> without <RETURN>.
