When you modify the threshold of the clock channel, a dotted line displaying the
current threshold level is displayed on the screen. It disappears in about 2 s after
you stop modifying the threshold.
• You can select the analog channel or the digital channel as the data source.
When the source is set to an analog channel, set SDA Thre with the pop-up
numeric keypad. You can also use the specified multifunction knob to set the
threshold.
Exchange Sources
Click or tap "SCL/SDA" or "SDA/SCL" under
Exchange to exchange the current clock
channel source and data channel source.
Set the Address Width
Click or tap the drop-down button of Width to select the address width. The available
choices include "7 Bits", "8 Bits", and "10 Bits". When "7 Bits" is selected, R/W bit is
not included in the address. When "8 Bits" or "10 Bits" is selected, R/W bit is included
in the address.
• 7: In 7-bit addressing, after the START condition, a slave address is sent. The
address starts to transfer from the first byte, as shown in the figure below. The
first seven bits of the first byte make up the slave address, and the eighth bit is
the LSB (least significant bit) which determines the direction of the message, also
called a data direction bit (R/W). A "zero" indicates a transmission (WRITE), a
"one" indicates a request for data (READ).

• 8: same as the 7-bit addressing. A R/W bit is included in the 8-bit addressing for
the slave address.
• 10: 10-bit addressing is compatible with, and can be combined with, 7-bit
addressing. As shown in the figure below, in 10-bit addressing, the first byte is
the special reserved address 10-bit Address Indicator to indicate the current 10-
bit address that is transferring.
