The PT-4000 POS Station is equipped with an Infrared (IR)
communication module located on the front of the station. If you are
having trouble finding this module, please see Front View on page 5. The
IR module consists of one Light Emitting Diode (LED) and one photo
sensor. The operation of the IR module is similar to the operation of a
television remote control device.
The IR module enables you to perform wireless, serial communication.
Use an SIR-specified application to transmit or receive data via the PT-
4000 POS Station IR module. You can set IR pre ferences in the Integrated
Peripherals screen in BIOS. Please refer to Chapter 5 for information on
the BIOS Setup program.
Follow the guidelines listed below when using the infrared
communication module to transmit or receive data.
•
Ensure that the PT-4000 POS Station IR module is properly
aligned with the other device’s infrared communication module.
The angle between the two infrared communication modules
should not exceed
±
15
°
.
•
There should be a clear path between the two Infrared
communication modules; otherwise, the optical signal will be
blocked. Likewise, do not place anything between the two
infrared communication modules during data transmission.
•
Make sure the distance between the PT-4000 POS Station IR
module and the other device’s infrared communication module is
not closer than 15 cm and does not exceed seven meters.
•
Do not move either the PT-4000 POS Station or the other device
during transmission of data; otherwise, data transmission will be
distorted resulting in loss of data or a system crash.
•
An error can occur if IR transmission is conducted in an
environment with high levels of noise. To avoid transmission
errors do not transmit infrared communication signals near
equipment with compressors, such as refrigerators or air
conditioners.
