Is the USB
connection OK?
The key and touchpad signals are transferred to the MC 62xx (possibly via a BF 250) with a USB cable.
If the keys do not work, carry out the following tests to find out, whether the keys, the USB cable or
the USB interface of the control component are defective.
Flowchart
No
Yes
The machine is on.
Is there any reaction?
No
Yes
The original USB interface is
defective.
Move the mouse pointer.
(The touchpad signals are transmitted over the
same USB cable as the key signals of the TE 6xx.)
Connect the USB cable for the key and touchpad signals
to another USB connector of the MC 6222 or BF 250.
Do the keys work now?
Checking the USB connection of TE 6xx
The USB connection is OK.
Connect a standard USB keyboard to
the MC 6222 or BF 250. (The keyboard should
have functioned with a Windows computer.)
Does the keyboard work?
Yes
No
The TE 6xx (or the
corresponding USB cable)
is defective.
The USB interfaces on the MC 6222 or BF 250 are defective.
The key assignment of a HEIDENHAIN keyboard differs from that of a standad computer keyboard.
For example, F12 switches the screen, and the DEL key on the numerical keypad executes the
CE command. The screen soft keys are assigned to F1 - F8.
The decisive factor is whether the control recognizes keystrokes via the USB line.
For a HEIDENHAIN key assignment plan for computer keyboards refer to the documentation of
the HEIDENHAIN iTNC 530 Programming Station.
