OmniBus II NI PXIe User Manual 6-1
6. MODULE CONFIGURATIONS
OmniBus II modules are available for many different protocols, including
MIL-STD-1553 with Avionics Discrete I/O, and ARINC 429/575. Both module
types include core discretes. Other standard and custom modules are available.
This chapter lists the part numbers for PXIe cards and for MIL-STD-1553 and
ARINC 429 modules and describes the features and functionality of each.
Note: OB2 products are not user-configurable. You cannot swap one module
type for another one with a different part number. You can exchange a module
only with an identical module. You can upgrade the OB2 products with
additional channels or protocols, but you must do this at the factory.
6.1 OmniBus II PXIe Boards
The OB2 PXIe card can host up to two modules, one per core. Table 6.1 below
lists OB2 PXIe carrier boards:

6.2 MIL-STD-1553 Modules
MIL-STD-1553 modules can have one or two dual-redundant databuses (chan-
nels). The part numbers for 1553 modules start with 5 (e.g., 511). The second digit
identifies the level of 1553 channel 0, and the third digit identifies the level of 1553
channel 1 (a zero indicates no second bus). Table 6.2 illustrates standard single and
dual channel 1553 modules.

Table 6.2—MIL-STD-1553 Module Part Numbering
Each MIL-STD-1553 channel is available in three levels of functionality (sum-
marized in the table below). All levels provide at least single terminal Bus Con-
troller, Remote Terminal (RT) and Bus Monitor operation, and user-configurable
RT response time. Advanced features include multi-terminal simulation (up to 32)
with concurrent monitoring and protocol error injection (word, gap, and message
errors). Level P MIL-STD-1553 modules provide variable transmit amplitude and
zero-crossing distortion.
