VXIplug&play Syntax
#include "age1439".h
ViStatus age1439_lbus_reset(ViSession id, ViInt16 lbusReset);
ViStatus age1439_lbus_reset_get(ViSession id, ViPInt16 lbusResetPtr);
Description
In order to avoid glitches in the local bus data, the local bus interface has strict requirements as to
the order in which modules in a VXI mainframe have their local bus interface reset. Upon power-
up or whenever any single module in the mainframe is put into a reset state, all modules should be
placed into the reset state from left to right. Then all modules can be take out of reset from left to
right.
Parameters
id is the VXI instrument session pointer returned by the age1439_init function.
lbusReset puts the Agilent E1439's local bus into reset or takes it out of reset.
AGE1439_LBUS_RESET_ON puts the Agilent E1439's local bus into reset while AGE1439_
LBUS_RESET_OFF takes the Agilent E1439 out of reset.
lbusResetPtr points to the current value of the lbusReset parameter.
Return Value
