(the default is 0 V) of the source channel. Pressing the multi-function knob
can quickly reset the threshold of the channel to 0 V.
When modifying the threshold of the source channel, a dotted line displaying the
current threshold level is displayed on the screen (in the same color as the
channel). It disappears in about 2 s after you stop modifying the threshold.
5. Specify the protocol version
Press Version and turn the multi-function knob to select the protocol
version that matches the LIN bus signal. You can also press Version
continuously to switch the protocol version. The available version include 1.X,
2.X and Both.
6. Specify the baud rate
Press Baud and turn the multi-function knob to select the signal rate that
matches the LIN bus signal. The default is 19200 bps. You can also press Baud
continuously to switch the current signal rate. You can select a preset baud rate
or “User”.
The preset baud rates include 19200 bps, 10417 bps, 9600 bps, 4800 bps,
2400 bps and 1200 bps.
When “User” is selected, press Setup and turn the multi-function knob
or the inner knob of the navigation knob to adjust the signal rate at a
relatively smaller step or turn the outer knob of the navigation knob to
adjust the signal rate at a relatively larger step. The adjustable range is
from 800 bps to 100 kbps.
Note: The larger the rotation amplitude of the outer knob of the navigation
knob is, the faster the variation of the value will be. When you need to
adjust the baud rate within a relatively larger range, this function can help
you quickly finish the setting.
7. Specify the display format
Press Format and turn the multi-function knob to set the display format of
the bus data to Hex, Decimal, Binary or ASCII. You can also press Format
continuously to switch the current display format.
Note: When the event table is turned on, the decoding data in the event table
will also be displayed in the format selected here.
