Functions listed alphabetically
age1439_fiber_setup
Sets the fiber interface parameters. This description also includes information on the following
functions which set up or query the fiber parameters individually:
age1439_fiber_BOF controls whether or not automatically generated BOF events are
transmitted.
age1439_fiber_BOF_get returns the current status of bofEnable.
age1439_fiber_crc sets up the fiber interface to transmit and receive cycle redundancy
checking to the same value.
age1439_fiber_crc_get gets the current status of crcEnable.
age1439_fiber_flow_control enables or disables transmitter flow control signals.
age1439_fiber_flow_control_get returns the value of flowControlMode.
age1439_fiber_mode is used to select the fiber mode.
age1439_fiber_mode_get returns the current value of fiberMode.
age1439_fiber_transfer_rate selects the transfer rate for fiber optical data.
age1439_fiber_transfer_rate_get returns the current value of transferRate.

Parameter
id is the VXI instrument session pointer returned by the age1439_init function.
bofEnable configures the automatic generation of BOF events. Generally, this is only used by modules in an
optical append chain.
AGE1439_BOF_ON is used in an optical append chain. When used in this manner, all but the last
module in the append chain should have BOF events enabled. The first module in the append
chain should also have fiberMode set to AGE1439_FIBER_MODE_GENERATE. This will cause
it to generate a BOF event after every EOE event, in other words, at the end of every data epoch it
sends. All subsequent modules in an append chain should have fiberMode set to AGE1439_
FIBER_MODE_APPEND. In this case, the module re-transmits received data epochs without
modification. The reception of a BOF event alerts the module to the opportunity to insert a data
epoch of its own, if available, between the reception of EOE and BOF events. AGE1439_BOF_
ON is only available when epochGenerate is ON and fiberMode is either generate or append,
otherwise this setting is silently accepted and ignored.
