Configuring Advanced Parameters
Caution
Do
not
modify the
Advanced
parameters without good reason. If you must
modify parameters for certain devices, the device manufacturer will recommend settings.
Modifying these parameters can have an adverse affect on data throughput rates. If settings
are incorrectly modified, some devices might disappear from the bus.
In the NI-FBUS Interface Configuration utility, click the
Advanced
button
on the dialog box for the port you want to configure. Figure C-1 shows the
Advanced Stack Configuration
dialog box.

The parameters involved in setting addresses are T1 and T3. These
parameters represent delay time values that your card uses to compensate
for the delays inherent in the device and in the set address protocol itself.
T1 describes the expected response delay of the device at a given address.
T3 describes the expected time for the device to respond at its new address.
