Chapter 7 RS-232C Communication using an External Synchronous Trigger The following section provides information on how to obtain output from the RS-232C interface in synchronization with a timing input into the input terminal. This operation does not require ASCII commands. Therefore, use this function if the KV-10/80 Series (or the KV mode) is used only to retrieve measurements. This can also be used when connecting a data logger to the LS-7000 Series.
Chapter 7 RS-232C Timing Chart The following timing chart applies to timing input and RS-232C data output (the measuring mode is not set to sample hold 2 or self-timing hold.) TIMING input ON OFF RS-232C data output Measured value 3.5ms • If the measuring mode is set to normal, auto peak hold, auto bottom hold, or auto peak-to-peak hold, the measured value will be transmitted at the moment timing input is turned ON.
