Changing Binary Numbers
There are two kinds of binary numbers that can be changed in the
CTS850: payload patterns and overhead bytes. As with other
numerical values, you can select preset values or enter specific
values by selecting Edit Byte.
To change a byte:
1. Highlight the byte with the knob (see Figure 2–16).
2. Change the byte by selecting one of the preset choices at the right
side of the display or to enter a different bit pattern, select EDIT
BYTE. This places the CTS850 into edit mode.
The highlighted
byte can be quickly
set to these
choices by
pressing the button
next to the desired
choice.
Select the byte to edit
by using the knob.
Select EDIT BYTE to change
the bits within the byte.
Figure 2–16: Selecting a Byte for Editing
When in edit mode, the choices along the right side of the display
change (see Figure 2–17). The highlight now applies to a single
bit.
