1. Note that in order to analyze the SCAM Protocol the trace needs to be recorded in the Capture SCAM Protocol mode first 3 3 THE BINARY DISPLAY FORMAT If the Structured display format is compared to a computer program written in a high level language the Binary display format is like the same program written in assembly language In the Binary format each event captured gets one line of display In this display format you can see the exact state of each SCSI control line at the time of the event s capture plus the state of the SCSI data lines and the Ancot expansion lines Furthermore the timing of the activity is shown accurate to the 4ns resolution of the Ultra 2080 There are several options in how the information is presented in the Binary format The control lines are shown in logic analyzer style as a rectangular waveform traveling down the page An active signal is shown as a thin line on the right side of the area dedicated to that control line Inactive signals show as thick lines on the left side of their respective areas Data can be shown as wide or narrow If the wide data format is chosen the low byte is shown first separated from the high byte by a hyphen If a parity error occurred that is shown by 3 8 ANCOT Corporation User Manual SCSI Bus Analyzer Ultra 2080 Section 3 an asterisk following the offending byte The asterisk may replace the hyphen separating the two bytes The bytes are show
