IrDA INTERFACE
The CE8000 Series unit comes with an integrated IrDA interface. See Figure
3 and Figure 4 to locate the IrDA interface.
An IrDA interface is an advanced technology that allows Infra Red
communication with peripherals and between computers. On CE8000 Series
unit, the main purpose of an IrDA Interface is to communicate with a printer
without any cable attachment. Communication with another computer or even
another CE8000 Series unit is also possible.
The way the printing is done using IrDA is mainly dependent on the
application program. You should refer to your application program user’s
guide for complete details.
The following is basic information on IrDA.
·
To communicate with the IrDA interface, the peripheral or the remote
computer should also have an interface supporting the IrDA protocol.
·
To communicate with the peripheral, point the bottom side of the
CE8000 Series unit at the IrDA receptor on the peripheral. Usually the
receptor looks like a dark plastic window about 17 x 7 mm (3/4" x 5/16").
Stay aligned within about ±15°
·
The communication can be done from a distance of up to one meter
(three feet).
·
The communication link is strong enough to withstand quite a large
displacement between the computer and the peripheral. In case of bad
reception, the communication protocol will restart the transmission of the
missed data block.
·
Direct, strong sunlight can degrade the communication link, increasing
the communication duration or even causing a breaking of the link.
Under direct sunlight, protect the CE8000 Series unit and the peripheral
with the shade of your body and keep units closer to the peripheral.
