4.1 Power
The scanner requires a minimum of 450mA at 9 V DC power. The interface cable
that comes with the scanner supports both direct power (where the scanner takes
power from the host machine) and external power (that's what the supplied power
adapter is for). A sufficiently robust POS system can support a scanner
successfully without external power; a POS system with a barely adequate power
supply may produce erratic performance (either of the POS system itself, or of the
scanner, or both) when a scanner is attached. Unless you are sure your POS
system can handle the load, it is recommended that you use the supplied power
adapter. When an external adapter is connected, the scanner does not take power
from the host.
The scanner turns on when power is supplied, and turns off when power is
removed. There is no on/off switch on the scanner itself.
Use only an AC/DC power adapter approved for the scanner. Use of other power
supplies may cause damage to the product, and void the factory warranty.
Follow the steps below when you need an external power connection to the
scanner (Refer to Figure 4):
1. Connect the interface cable to the bottom of the scanner.
2. Connect the other end of the interface cable to the host (refer to your host
manual to locate the correct port).
3. Plug the power supply into the power jack on the interface cable.
4. Plug the other end of the power supply into an AC outlet.
4.2
Connecting to the Host
The interface cable comes with different host-end connectors, depending on the
host. Follow the steps below to connect the interface cable to the host.
1. Make sure that the power of the host system is off.
2. Plug the host end of the interface cable to the appropriate connector on the
host system.
3. For those cases where external power is used, plug the external AC power
adapter into the jack on the interface cable.
4. Turn on the host system.
