Functions listed alphabetically
age1439_fiber_xmt_signals
Sets the transmitted values of PIO1, PIO2, DIR, and NRDY FPDP control signals on the fiber
transmitter.
VXIplug&play Syntax
#include "age1439".h
ViStatus age1439_fiber_xmt_signals(ViSession id, ViInt16 pio1, ViInt16 pio2, ViInt16
dir, ViInt16 nrdy);
Description
These are embedded Serial FPDP signals. The use of these bits is optional. Serial FPDP does not
use these four signals directly, but simply transmits them from sender to receiver. These functions
set the value of PIO1, PIO2, DIR and NRDY bits on the fiber transmitter. The default value of
these signals is 0.
Parameter
id is the VXI instrument session pointer returned by the age1439_init function.
pio1 Programmable I/O bit on the fiber transmitter for user defined purposes.
pio2 Programmable I/O bit on the fiber transmitter for user defined purposes.
AGE1439_FIBER_SIG_ON FPDP control signals enabled.
AGE1439_FIBER_SIG_OFF FPDP control signals disabled. This is the default value for all
signals.
Note The following are FPDP signals that are accommodated in the Serial FPDP protocol. For further
information on these signals refer to ANSI/VITA 17-1998, Front Panel Data Port Specifications.
dir sets the dir FPDP control signal.
nrdy sets the nrdy FPDP control signal.
Return Value
AGE1439_SUCCESS indicates that a function was successful.
Values other than AGE1439_SUCCESS indicate an error condition or other important status
condition. To determine the error message, pass the return value to “age1439_error_message” on
page 102.
