Psion Mobile Devices Developers Guide
8.1 Overview
The Mobile Devices SDK enables applications to detect and control peripherals—such as docking stations,
tethered devices, and cards inserted in card slots—attached to the following Psion computers:
•753x
•8515
• 8525 / 8530
• Workabout Pro (7525)
• Workabout Pro G2 (7527)
• Workabout Pro3 (7527)
• Ikôn (7505)
•NEO (PX750)
Docking stations and card slots for the following Psion computers are controlled through the
corresponding HDKs:
• Omnii XT10 (7545XV)
• Omnii XT15 (7545XA)
• Omnii RT15 (7545XC)
•EP10 (7515)
8.2 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.
8.3 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.
8.4 Docking Station
The Mobile Devices SDK can detect the type of docking station the Psion 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.
