Commands Listed in Alphabetical Order
SDIDATASSM set
s the ARINC429 DATA field width to 23 bits wide (covering
bits 9 through 31 of the 32 bit packet)
Examples
BUS:B1:ARIN
C429A:DATA:FORMAT DATA
sets the ARINC429 DATA field to
19 bits wide.
BUS:B1:ARINC429A:DATA:FORMAT? might return SDIDATASSM, indica
ting
that the ARINC429 DATA field is 23 bits wide.
BUS:B<x>:ARINC429A:POLarity
This command sets the polarity of the ARINC429 bus (normal or inverted).
Conditions
This command requires installation of a DPO4AERO application module for
MDO4000C models, or MDO3AERO for MDO3000 models.

BUS:B<x>:ARINC429A:SOUrce
Arguments
NORMal - A positive differential pulse in the first half of a bit period that then
returns to zero differential represents a 1 on the differential source.
INVERTed - A positive differential pulse in the first half of a bit period that then
returns to zero differential represents a 0 on the differential source.
Examples
BUS:B1:ARINC429A:POLarity INVERTED sets the polarity so that a positive
differential pulse in the first half of a bit period that then returns to zero differential
represents a 0 on the differential source.
BUS:B1:ARINC429A:POLarity? might return NORMAL.
BUS:B<x>:ARINC429A:SOUrce
This command specifies the source for the differential input for the ARINC429
bus.
