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

is the VXI instrument session pointer returned by the age1439_init function.

Programmable I/O bit on the fiber transmitter for user defined purposes.
