摘要： Monitoring apparatus according to the present disclosure is capable of monitoring binary coded communications between a plurality of stations. The apparatus includes receiver means for receiving binary signal and register means for sampling received binary signals in such a manner that they may be stored into memory means. Display means is provided for retrieving and displaying alpha-numeric representations of the binary signals so that the individual characters of the binary coded communications may be displayed on the display read-out. One feature of the monitoring apparatus resides in a parity check apparatus wherein the parity of the binary coded characters may be verified.
