Table 6.10—MIL-STD-1553 Module Part Numbering

ARINC 708 modules are available with one receiver and one transmitter or two
receivers  and  two  transmitters.  ARINC  708  channels  communicate  on  the  air-
borne  pulse  Doppler  weather  radar  display  databus.  Each  channel  can  be  inde-
pendently  switched  to  operate  on  either  of  two  buses.  All  channels  can  be
configured  for  variable  bit  length.  Parametric  versions  of  ARINC  708  modules
have variable transmit amplitude.

The ARINC 708 modules also contain Avionics Discrete I/O, see Section 4.5 for
more details.

6.5.1 Software-Selectable Bus Termination

Each databus on all OmniBus ARINC 708 modules has a 75-ohm termination re-
sistor  that  can  be  switched  across  the  direct-coupled  terminals  under  software
control. Though direct coupling is standard for ARINC 708, transformer coupling
may  be  used.  When  the  bus  is  transformer  coupled,  the  direct-coupled
termination  resistance  must  be  off,  and  external  couplers  and  terminators  are
required.  See  Appendix  A  for  more  information  about  bus  termination  and
transformer versus direct coupling.

6.5.2 Variable Bit Length

All OmniBus ARINC 708 modules can support messages with user-defined
number of bits. Variable bit length mode is software-selected at the channel level.
Special functions are provided in the BTIDriver API to read and write messages
with a bit count of 1 to 1865 (116 x 16). This allows ARINC 708 channels to be
used with other transfer protocols that vary from the standard (1600-bit word)
display databus.

6.5.3 Variable Transmit Amplitude

For OmniBus II ARINC 708 modules with parametric capability, the amplitude
of  the  transmitted  databus  signal  can  be  varied  under  software  control.  Using
BTI708_ParamAmplitudeConfig,  the  OmniBus  II  has  extended  functionality
from  the  OmniBus  Family.  The  configuration  value,  configval,  now  allows  for
setting a high and a low range. The lower 12 bits of dacval represent the transmit
amplitude.  The OmniBus II has a resolution of 8 bits, so the least significant 4
bits are “don’t cares.” The full-scale value of FF0h is the default setting.
