Abstract
When setting (changing) a reception mode in a receiving unit 40, a CPU 62 issues a reception mode command to the receiving unit 40. Having received the command, a serial interface 53 writes the command to a command buffer 52. A protocol controller 50 analyzes the command which has been written to the command buffer 52 to determine whether the reception mode is a FIX mode or an UNFIX mode, and writes a corresponding status (a device ID, unique ID, mode, etc.) to a status memory 54. Then, when data is received from a transmission unit 20, the receiving unit 40 refers to the status which has been written to determine whether or not the received data is from a transmission system which has been set.
