The IR communications device features the following:

Wireless communications

Small and lightweight design

High transmission speed

Freedom from the codes/regulations and licenses which differ from country to country, unlike radio devices

The BHT-6000’sIR communications device isIrDA-compliant.IrDA stands for Infrared Data Association, which has defined hardware (IrDA Serial Infrared Physical Layer Link,IrDA-SIR)and communications protocols for IR communications.

The BHT-6000’sphysical layer complies with theIrDA-SIR1.0, with a maximum transfer distance of 1 m and maximum transmission rate of 115.2 kbits per second.

The BHT-6000adopts the exclusiveBHT-Irprotocol which allows you to develop user programs for IR communications inBHT-BASIC3.0, as can be done with conventional wire communications.
