Zusammenfassung:PROBLEM TO BE SOLVED: To provide a communication line monitor device of general versatility capable of complying with a new communication protocol without redesigning/reproducing a communication line monitor. SOLUTION: In the communication line monitor device, a USER LOGIC circuit 4 inside an FPGA can change a logic circuit for a communication signal detection by a program according to a communication protocol. Therefore, change or addition of an electronic circuit as the communication line monitor device is facilitated, and redesigning/reproducing of the communication line monitor device can be dispensed with. Consequently, versatile usage ready for a plurality of communication protocols is allowed. COPYRIGHT: (C)2008,JPO&INPIT
