vi = contains a session handle to the instrument. This handle is obtained by the function and remains valid until the
session is closed.
lxiLine = an integer input value that indicates which LXI Trigger Bus channel the function will configure. Valid
input values: 0 to 7.
inOut = an integer input value that indicates whether the specified LXI Trigger Bus channel will be configured for
input or output. Valid input values: 0 or 1.
transmissionScope = an integer input value indicating whether transmissions on the specified channel will be input
from an output to the external LXI bus, or will be kept internal to the EX1629. Valid input values: 0 or 1.

The inOut parameter configures the direction of the LXI Trigger Bus channel. The permissible values indicate the
following:
Decimal Hex
Value Value
0 0x00 VTEX1629_LXI_INPUT
1 0x01 VTEX1629_LXI_OUTPUT
The transmissionScope parameter indicates whether the specified LXI channel is configured to communicate with
other devices on the external LXI bus or simply configured to communicate on the internal LXI bus. In the case of
an output, the transmissionScope indicates whether the output will be driven out onto the external LXI bus in
addition to being driven on the internal LXI bus. In the case of an input, the transmissionScope determines if the
input is read from the external bus or read from the internal bus. The permissible values indicate the following:
Decimal Hex
Value Value
0 0x00 VTEX1629_LXI_INTERNAL
