Chapter 2. Getting Started the BHT and System Mode
[5.5] Communications test
In System Mode, you may test the optical interface port and direct-connect interface
port.

■ Preparation for the optical interface test

Arrange two BHTs, one as a master station and the other as a slave station (to be
tested) with their IR ports facing each other as illustrated below. In this test, the slave
BHT transmits data to the master BHT and receives the data sent back from the master
BHT.

■ Preparation for the direct-connect interface test

Arrange the 3-pole mini stereo plug as illustrated below and connect it to the direct-
connect interface port on the BHT.
