2.2 Connecting the programming
station
Connecting the keyboard for the programming
station
Connect the programming station keyboard to an available USB port
on your computer.
Then install the driver for the USB dongle from the programming
station CD.
The programming station software then automatically recognizes the
connected programming station keyboard.
The rear of the programming station keyboard has a USB port, to
which you can attach another USB device.
The additional USB device attached to the programming
station keyboard must not draw more than 200 mA of
current.

Mounting the cable clamps for the USB cable

The rear panel of the programming station keyboard has five pockets
(see figure at right) in which you can glue the provided cable clamps.
The cable clamps serve to relieve the strain on the USB connector.
HEIDENHAIN recommends using these cable clamps to
prevent loosening of the USB connector and damage to the
connection on the PCB.
To fasten the cable clamps, proceed as follows:
 Lay the programming station keyboard with the keys downward on
a flat surface
 Remove the protective film on the bottom of the cable clamp
 Place the cable clamp into the desired pocket on the programming
station keyboard and press:

Use pockets 1, 2 or 5 if the cable is to exit to one side

Use pockets 3 or 4 if the cable is to exit straight out
 Connect the USB cable and insert it in the cable clamp

Place the fastener from above on the clamp and press downward
until the USB cable is fastened
