Overshoot on PC Printer Ports
The data lines on some PC parallel printer ports have excessive
overshoot that may cause communications problems when pre-
sented to the CLK pin of the AD8328. The evaluation board was
designed to accommodate a series resistor and shunt capacitor
(R2 and C5 in Figure 11) to filter the CLK signal if required.
Installing Visual Basic Control Software
Install the CabDrive_28 software by running the setup.exe file on
disk one of the AD8328 evaluation software. Follow the on-screen
directions and insert disk two when prompted. Choose installation
directory and then select the icon in the upper left to complete
the installation.
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 com-
municate with the AD8328 (Figure 9).

Controlling Gain/Attenuation of the AD8328
The slide bar 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 slide bar is displayed in decimal,
binary, and hexadecimal (Figure 10).

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 checkbox 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 slide bar into memory, while the RM1 button
recalls the stored value, returning the gain slide bar to the stored
level. The same applies to the X->M2 and RM2 buttons.
