For example, assume the returned bitmap value is 34061. The binary equivalent
of this value is as follows:
1000010100001101
For the above binary number, the following bits are set to “1”: 16, 11, 9, 4, 3 and 1.
Using
Table14-2 , the following annunciators are on: REL, REM, EDIT, AUTO, 4W
and EDIT.

Weighted Value* 32768 16384 8192 4096 2048 1024 512 256
Binary Value 0/1 0/1 0/1 0/1 0/1 0/1 0/1 0/1

Weighted Value* 128 64 32 16 8 4 2 1
Binary Value 0/1 0/1 0/1 0/1 0/1 0/1 0/1 0/1
* The weighted values are for bits that are set to “1.” Bits set to “0” have no value.
Note that not all of the above annunciators shown in Table14-2 are used by the
Series 2600.
LOCAL lockout
The front panel LOCAL key is used to cancel remote operation and return control
to the front panel. However, the LOCAL key can be locked out to prevent a test
from being interrupted. When locked, the LOCAL key becomes a NO-OP (no
operation). Use the following attribute to lock or unlock the LOCAL key:
display.locallockout = lockout
where lockout is set to one of the following values:
0 or display.UNLOCK
1 or display.LOCK
LOCAL lockout example:
The following command locks out the LOCAL key:
display.locallockout = display.LOCK
