and then typing <INS> (or 'AN') to insert signals. Select ' Vbat ' in the
selection list and type <CR>.
The VBAT trigger signal can be selected as X (don't care), OK (no violation),
or ERR (VMEbus violation found).
VBAT command screen
The operation of the VBAT-PB is controlled from a dedicated command
screen. This is activated by executing the ' Vbat ' command, i.e. by placing
the cursor on 'Vbat' on the main command bar and typing <CR>, or simply type
' V ' .
The VBAT command screen should now appear, as shown below.

The Violations command
Enable
The VBAT-PB is by default disabled when the power is turned on [or
whenever the VBT-325 is reset]. It could otherwise have jammed the VBT-325
if your system suffers from repetitive VMEbus timing violations. To enable the
VBAT, select the command ' Vi o l a t i o n s / E n a b l e '
