Psion Teklogix Mobile Devices SDK Developers Guide 67
10.1 Overview
The Mobile Devices SDK enables applications to detect and control peripherals attached to
Psion Teklogix computers, such as docking stations, tethered devices, and cards inserted in card
slots.
10.2 Definition Of Terms
Some terms used in the chapter have precise definitions. They are defined in this section.
Adaptor: This is a hardware component that supports the connection of the computer to a
network or a peripheral device. An adaptor can be a printed circuit board, a PC card, or circuitry
that is part of the mother board.
Device driver: This is a software component that permits a computer system to communicate
with a device. In most cases, the driver also manipulates the hardware in order to transmit the data
to the device.
Peripheral or peripheral device: A device, such as a hard drive, printer, radio or modem, that is
connected to a computer and is controlled by the computer’s microprocessor.
10.3 Events
The following peripheral event types are detected by the Mobile Devices SDK:
• Adaptor event
• Docking station event
• Interface event
• Tether port event
Adaptor event: Occurs when the adaptor is connected to or removed from the slot.
Docking station event: Occurs when the device is inserted into or removed from the docking
station.
Interface event: Occurs when the device is connected to or removed from the slot/port.
Tether port event: Occurs when the device is connected to or removed from the tether port.
10.4 Peripheral and Card Slot Power
For information on querying and controlling the power status of peripherals see Section 6.3:
“Peripherals”.
For information on controlling the power status of card slots, see Section 6.2: “Card Slots”.
10.5 Docking Station
The Mobile Devices SDK can detect the type of docking station the Psion Teklogix computer is
currently resting in. A docking station is an external hardware component. It can be one of the
following:
• Portable docking module
• Battery charger
•Cradle
A docking station can include one or more additional serial ports, and USB ports.
