Returns the current value of PIO1, PIO2, DIR, and NRDY bits present on the fiber transmitter.
VXI plug&play Syntax
#include "age1439".h
ViStatus age1439_fiber_xmt_signals_get(ViSession id, ViPInt16 pio1, ViPInt16 pio2,
ViPInt16 dir , ViPInt16 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
display the value of recovered PIO1, PIO2, DIR and NRDY bits on the fiber transmitter.
Parameter
id is the VXI instrument session pointer returned by the age1439_init function.
pio1 returns the current value of pio1 .
pio2 returns the current value of pio2 .
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 returns the current value of dir.
nrdy returns the current value of nrdy.
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 .
