4. Be sure you make a loop in the cable, which will fit under the end-cover,
as this is an essential part of the strain relief (see right picture above).
5. Guide the cable through the exit slit and carefully mount the end cover.
6. (If you have an older type of cover: lock the two little clips by shifting them

2.2 POWERING THE SIRIUS SCANNER.
The Sirius is designed so that you only need one single and simple cable for
both data and power using “Direct Power” (or “Power Of Terminal”).
This requires that your PC/POS system is providing sufficient power on its
data port (RS-232, USB or KBW). See Appendix B for details.
All applicable Sirius interface cables have a power injector to connect an
optional external PSU in the case the POS system does not supply (sufficient)
DC power for the scanner. See next page for illustration.
A standard PC USB port will supply sufficient power for the scanner to function
without any problems. The Sirius can also be connected to the „USB plus power‟
ports (the green connector).
If you use Key Board Wedge interface, the PC/POS system usually supplies
sufficient power. Some PC/POS systems may have problems supplying the
required power via the Key Board connector. In this case you can easily add
an external power supply and connect it via the available power injector in the
KBW cable.
