USB hub connecting cable
Plug this cable into any free USB port on the control computer.
Connecting the cable allows the integrated keyboard, in-built LCD touch
screen and the two side-mounted USB ports to be used.
The USB hard drive cannot be used without first connecting
an external power supply to the USB ports. This is because the
USB ports alone are unable to supply sufficient power.
3.2 Power supply to the CNC control panel
D-sub 9-pin plug
This plug must be used with the isel iSR/iPC series control computer. It
allows the power button connecting cable to be plugged into the right-
hand side of the CNC control panel, the indicator LEDs into the front
panel of the equipment cover and the TFT power supply into the socket
provided on the control computer. Insert the plug into the D-sub socket
provided on the control computer in the switching cabinet.
