cable for direct connection to PCs with a DB-9 connector on one end (

Earth Ground
Please note that the Hengstler cable is supplied with a flying pigtail on the printer end. This
pigtail is intended to be fastened under the grounding screw, as shown in Fig. 2, to provide
maximum reduction of radiated electrical noise.
For additional protection against accidental cable removal, the cable tie-downs (
Fig. 2)
are provided as a point to which you may fasten cables using cable ties (not provided).
USB
The USB versions of the eXtendo® printer employ a standard digital camera USB interface
cable (5 pin Mini-B connector on the printer end) to communicate with the host. Be sure
that the Mini-B connector is fully engaged with the mating connector on the printer. The
other end of the cable plugs into a USB port on the host.
