Inserting A Warrington In The Quad Docking Station
Warrington Hand-Held Computer User Manual 195
7.8.3 Inserting A Warrington In The Quad Docking Station
Slide the Warrington into the cradle portion of the quad dock until lightly latched.
The hand-held detects that it is in a quad dock and momentarily displays the appropriate
icon in the navigation bar at the top of the screen:
The LED on the hand-held unit lights up to show it has external power and may start charg-
ing the battery.
Interaction with the Warrington while in the quad dock is a function of the user application
software used to communicate with the host network.
7.8.4 Network Access
The quad docking station has one 10/100 Ethernet port. You can insert up to four hand-held
units. The hand-helds are connected to an internal USB hub. The hand-held unit automati-
cally detects insertion into a quad docking station and loads the appropriate drivers to
communicate with the USB/Ethernet converters.
7.8.4.1 Network Addressing
Although the USB converters have fixed Ethernet MAC addresses, there is generally no cor-
relation between these addresses and a specific hand-held. The host application uses
standard TCP/IP protocol to name, locate and communicate with a specific Warrington on
the network.
If a link is established between a Warrington and a host, the application on the host and on
the hand-held must have a recovery mechanism in the event that the Warrington is removed
from the dock and the link is interrupted.
7.8.5 Battery Charging – LED Behaviour
The quad docking station supplies DC power to enable the Warrington internal fast charger.
Charge status is displayed on the hand-held LED–the LED turns red while the battery is
being charged and turns green once the charge is complete. If the battery is fully charged
when the unit is inserted in the docking station, the LED flashes red for less than a second
and then turns green. Battery charging continues whether the Warrington is switched on
or off.
It can take up to 4 hours to fully charge the internal battery.
