For information about .condition, .enable, .event, .ntr, and .ptr registers, refer to
(on page E-
Enable and transition registers
(on page E-18). The individual bits of this register have the following
meanings:
Bit Value
Description
B0
status.operation.instrument.lan.CONNECTION
status.operation.instrument.lan.CON
Set bit indicates that the LAN cable
is connected and a link has been
detected.
Bit B0 decimal value: 1
B1
status.operation.instrument.lan.CONFIGURING
status.operation.instrument.lan.CONF
Set bit indicates the LAN is
performing its configuration
sequence.
Bit B1 decimal value: 2
B2-B9 Not
used
Not available
B10
status.operation.instrument.lan.TRIGGER_OVERRUN
status.operation.instrument.lan.TRGOVR
Set bit indicates one or more
enabled bits for the operation status
LAN trigger overrun register is set.
Bit B10 decimal value: 1024
B11-B15 Not used
Not applicable
As an example, to set bit B0 of the operation status LAN summary enable register, set
status.operation.instrument.lan.enable
= status.operation.instrument.lan.CON
.
In addition to the above constants,
operationRegister
can be set to the numeric equivalent of the bit to set.
To set more than one bit of the register, set
operationRegister
to the sum of their decimal weights. For
example, to set bits B1 and B10, set
operationRegister
to 1,026 (which is the sum of 2 + 1024).
