Display Time Information

Time Stamp
The time, when the head of character of each frame running through the communication channel is received,
is recorded in the capture buffer and displayed as following.
Min:Sec:10ms Yr/Mon/Day Hr:Min Mon/Day Hr:Min:Sec
Set the unit of time stamp from [MENU] -> “Record control” -> “Additional info.”.
Time stamp information consumes 4 bytes (for 3 units of time) or 8 bytes (for 5 units of time) of memory.

Idle Time
The time, when SD and RD keep non-communication status and a changeless status of signal lines, is record-
ed as following.
Resolution Range Example
100msec. 0~999.9sec.
10msec. 0~99.99sec.
1msec. 0~9.999sec.
Set the unit of idle time from [MENU]->“Record control ”->“Additional info.”
The time until reaching to be ASYNC, or receiving a specific address in HDLC is considered to be idle state with/
without data existence.
If the time of one bit is slower than idle time (low speed communication), idle time may not be accurate.
“OVER” is displayed if it exceeds the range.
2.6 Record Control
Line State Display
Status of control lines (RTS, CTS, DCD, DTR, DSR, RI) and trigger input (TRG) can be displayed in waveform.
Control lines are displayed as high level when the line state LEDs light in read.
<Example of line state display>
The correspondences between line state LED and signal name on the screen.
Signal name Line state LED Signal name
RTS RS(4) (5)CS CTS
DTR ER(20) (6)DR DSR
(8)CD DCD
(22)CI RI
Names of line state LED are conformed to JIS X5101.
Set to record the control lines from [MENU] -> “Record control ” -> “Additional info.” -> “Line state”.
