PROBLEM TO BE SOLVED: To provide an information processing system allowing the receipt of radio data from at least one optional transmission unit in one receiving unit and the optional change of the selection of a usable receiving unit. SOLUTION: A CPU 62 reports a receiving mode command to a receiving unit 40 in the set (change) of a receiving mode in the receiving unit 40. A serial interface 53 which received the command writes this command to a command buffer 52. A protocol controller 50 analyzes the command written in the command buffer 52 to determine whether the receiving mode is FIX mode or UNFIX mode, and writes the corresponding status (device ID, unique ID, mode, etc.), in a status memory 54. When data are received from a transmission unit 20, the receiving unit 40 determines whether the received data are from a set transmission system or not in reference to the written status. |
