7.
If necessary, scan the appropriate host bar code (for non-autodetected interfaces). See the specific host
chapter.
Connecting STB2000-F Cradle
1.
Insert the host interface cable into the cradle's USB/host port. See Figure 1-2 on page 1-4 .
2.
Connect the forklift power supply to the cradle's power port, if applicable.
3.
Optionally: Insert the power supply cable ferrite into the support features on the cradle bottom and run the host
and power cables into their respective cable grooves, or use cable ties to secure them to the mounting plate
after attaching it to the cradle. For more information about mounting options and procedures, refer to the
documentation included with the cradle.
4.
If necessary, scan the appropriate host bar code (for non-autodetected interfaces). See the specific host
chapter.
Changing the Host Interface
To connect to a different host, or to the same host using a different cable:
1.
Disconnect the power supply from the cradle, if used.
2.
Disconnect the interface cable from the host.
3.
Connect the interface cable to the new host, or the new interface cable to the existing host.
4.
Reconnect the power supply, if required.
5.
If necessary, scan the appropriate host bar code (for non-autodetected interfaces). See the specific host
chapter.
Supplying Power to the Cradle
The cradle receives power from one of two sources:
•
An external power supply.
•
When connected to the host through an interface cable that supplies power.
The cradle detects whether the host or the external supply is supplying power. It always draws power from the
external supply when available, regardless of the presence of power from a host.
Using the USB Interface to Supply Power
When the cradle is connected to the host via the USB interface, the USB port can power the cradle and an external
power supply is not necessary. Note that powering from a USB host charges the device at a slower rate than
charging from an external power supply. Additionally, depending on the level of activity, the device may not charge
at all.
NOTE Disconnect the power supply before changing host cables, or the device may not recognize the new host.
Different cables are required for different hosts. The connectors illustrated in each host chapter are examples
only. The connectors may be different from those illustrated, but the steps to connect the device remain the same
CAUTION If the device does not recognize the host, disconnect the power supply, then reconnect after
connecting the host cable.
