RUNNING AD8328 SOFTWARE
To load the control software, go to Start, Programs,
CABDRIVE_28 or select the AD8328.exe file from the
installed directory. Once loaded, select the proper parallel
port to communicate with the AD8328 (see Figure 24).

CONTROLLING GAIN/ATTENUATION OF THE
AD8328
The SLIDER controls the gain/attenuation of the AD8328,
which is displayed in dB and in V/V. The gain scales 1 dB
per LSB. The gain code from the position of the SLIDER is
displayed in decimal, binary, and hexadecimal (see Figure 25).

TRANSMIT ENABLE AND SLEEP MODE
The Transmit Enable and Transmit Disable buttons select the
mode of operation of the AD8328 by asserting logic levels on
the asynchronous TXEN pin. The Transmit Disable button
applies Logic 0 to the TXEN pin, disabling forward transmission.
The Transmit Enable button applies Logic 1 to the TXEN pin,
enabling the AD8328 for forward transmission. Checking the
Enable SLEEP Mode box applies Logic 0 to the asynchronous
SLEEP pin, setting the AD8328 for SLEEP mode.
MEMORY FUNCTIONS
The Memory section of the software provides a way to alternate
between two gain settings. The X→M1 button stores the current
value of the GAIN SLIDER into memory, while the RM1 button
recalls the stored value, returning the gain SLIDER to the stored
level. The same applies to the X→M2 and RM2 buttons.
