MODULE CONFIGURATIONS
6.4 ARINC 429 Modules
The preferred ARINC 429 I/O modules for OmniBus II are listed in the table
below. Each channel of those marked as “selectable” in the table can be config-
ured as either a receiver or a transmitter.
Part No. 429 Channels
R = receive and T = transmit
* Also includes ARINC 717 channels
Table 6.7—ARINC 429 Module New Applications Part Numbering
Though the above ARINC 429 modules are preferred and recommended for new
applications, Ballard does offer OmniBus II modules in the table below in con-
figurations and functionality corresponding to those in the original OmniBus
family. Pinout and functionality for these modules are described in the original
OmniBus manuals.
R = receive and T = transmit
* Also includes ARINC 717 channels
Table 6.8—ARINC 429 Module Deprecated Part Numbering
The 435 and 455 modules include ARINC 717 channels (as described in Section
6.6). Note that for 435 modules each ARINC 429 receive channel is only availa-
ble when the corresponding 717 receive channel is not configured for bipolar.
ARINC 429 modules are available in many combinations of receive/transmit
channels and features. All ARINC 429 receive channels feature automatic speed
detection and independent label and SDI filtering. Each transmit channel auto-
matically maintains accurate label repetition rates. To support data transfer pro-
tocols, aperiodic words may be transmitted without altering the timing of
periodic words. Both receive and transmit channels may be independently set for
standard low or high speed (12.5 or 100 Kbps). As shown in the table, some
ARINC 429 modules provide capability to control the transmitted waveform,
frequency, and output state.
