mbus A429 Parametric Port


A429 Parametric Port Config function sets up the selected parametric port configuration. In addition to A429 Port Config function, voltage configuration is also available. This function opens a port and provides a portHandle. This portHandle must be wired to all subsequent VIs that uses this port.

error in in error conditions that occur before entering the function
sessionHandle in reference to the current Multibus session block handle
parametricPortNumber in parametric port index to configure
speed in selected port speed: Low or High
loopback in ARINC 429 words are looped back from Tx port to the Rx port
parity in selected port parity : Odd, Even, None. With parity set to None, port parity is not defined. Parity bit is transmitted with the value set by the application and no parity validity is checked upon receive
busLoad in number of ARINC 429 bus loads (all Rx units on the bus)
voltage in output peak to peak voltage in Volts
sessionHandle out reference to the Multibus session
portHandle out reference to the configured port
portNumber out configured port index
error out out error information
function return out function execution status

Handle parameters are available as input and output. Output is a copy of the input and may be used to daisy chain successive VIs and reduce wire density.


Available in Multibus VI 1.0 and later.
