<p>PURPOSE:To facilitate the installation by retrieving a bit rate at the reception side whose bit rate is coincident with that of the sender side while selecting sequentially prest plural kinds of bit rates so as to allow the installation person to eliminate the need for the adjustment of the bit rate. CONSTITUTION:A bit rate selection means selecting a preset bit rate sequentially every reception of a selection signal and a control section discriminating whether or not the normal reception is finished in the selected bit rate, revising the bit rate when not finished and fixing the reception bit rate when finished, are provided. Thus, in receiving the signal normally within the total time of the consecutive time of the data group and the gap time in the bit rate, since the received bit rate is fixed to the value, the bit rate is set easily.</p> |
