6.2 Connecting to the Host
Follow the steps below to connect the interface cable to the host.
1. Make sure the power of the host system is off.
2. Connect 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.
6.3 Power Connection
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.
The scanner requires a minimum of 1.35W at 5 VDC 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.
To ensure steady performance, the host system should be capable to supply a
minimum of 260mA of current @ 5VDC. Unless you are sure your POS system
can handle such loading, it is recommended that you use the qualified power
adapter. When an external adapter is connected, the scanner will automatically
switch off the direct power from host to scanner.
Use only an AC/DC power adapter approved for the scanner. Use of
other power supplies may cause damage to the scanner, and void the
factory warranty.
Follow the steps below when you need an external power connection to the
scanner:
1. Connect the interface cable to the bottom of the scanner (shown in
Figure 6).
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.
