Data value matching
You can trigger on a specific data value for RS-232 bytes. If you defined an end-
of-packet character to use for RS-232 bus decoding, you can use the same end-of-
packet character as a data value for trigger data matching. To do so, choose the
Tx End of Packet or the Rx End of Packet character as the Trigger On selection.
You can also trigger on a specific data value for other buses.
Parallel bus trigger data matching
Optimum parallel bus trigger performance is achieved by using only analog
channels or only digital channels.
