5.2 TAP Specific Settings

The system SCANFLEX supports up to 8 independent TAPs. The SFX-TAP2(4)/C supports two
or four TAPs respectively. Each TAP can be configured in its properties individually. These are
the TAP specific settings:

•

Aktivierung der TAPs

•

Testbus output and Input voltages

•

Inline resistor for outputs

•

Pull down resistor for inputs

•

activation of the power relay

•

ADYCS II ™ - the UUT-TCK-TDO delay

The TAP specific settings are made as follow:

First go to

View / Tester Configuration

. Alternatively, you may use the

icon. The purpose

is to create a configuration for a given hardware constellation. In cases, no

Tester

Configuration

is existing yet, it must be created. For this, press

Configuration

in the left panel.

Press the button ‚new’ in the right panel. Type in the name of the new configuration. In this case
use

SFX_TAP4

. Confirm with

OK

.
