Infrared transceiver

Infrared communication creates a data link between two communications devices through an infrared beam of light. On the T68i, this link is used to connect with desktop computers, PDAs, Sony Ericsson handheld computers, laptop PCs, other phones (for example, the T39), and other hardware supporting the standard. The Infrared Data Association (IrDA) has set the hardware and software standards that form the infrared communication links. The T68i complies with the IrMC 1.1 specification, which defines how mobile telephony and communication devices can exchange information. In the T68i, the IrMC 1.1 specification is also used for communication via a cable.

Key benefits of using the T68i with its built-in infrared transceiver:

True wireless communication

Low power consumption

Secure data transmission with the IrDA DATA standard

Ability to send and receive e-mail and data on the connected PC/PDA

Ability to connect to the Internet or intra- net/LAN from the connected PC/PDA

Ability to manage the phone book from a

PC

Exchange of business cards and calendar events with vCard/vCalendar compatible devices

Connection via infrared

IrDA is a point-to-point communication link between two infrared ports. The infrared beam has to be directed towards the target infrared port and as long as the two infrared ports are within sight and range, the devices exchange data. For optimal performance, place the T68i within a metre and at an angle of 30 degrees to the infrared port on the PC/PDA, or other phone. An advantage of the necessary proximity of devices is reduced risk of transmitting data to other nearby devices. An infrared link is a serial connection, which means that data bits are sent one after another in a long stream. The IrDA–SIR Data Link Standard is a protocol that makes transmission of data faultless. The standard provides a high level of noise immunity, which means that the connection is not affected by fluorescent light, sunlight and electromagnetic fields – making it suitable for the modern office environment.

Connection via cable

The infrared connection is not always the best solution when connecting to a PC/PDA. Indeed, it is not always even possible. The DRS-11 cable provides the same connectivity between the phone and another unit.

The DRS-11 cable supports a subset of the signals in the RS-232 standard, as detailed in “Infrared transceiver technical data” on page 69.
