Combination Module - MIL-STD-1553B and Discrete I/O CM1

 

Combination Module - CM1

Combination MIL-STD-1553B and Discrete I/O

The CM8 function module is the improved assisted mode versions of the legacy CM1 function module and is the choice for all new programs.

NAI's latest generation combination module (CM1) is used on our rugged COTS Multifunction Embedded I/O Boards, Single Board Computers (SBCs), and Configurable Systems offered in OpenVPX, cPCI, VME, and PCI/PCIe configurations.

Offering both MIL-STD-1553B communications and discrete I/O this module allows for greater flexibility by offering the functionality of two modules in one.

NAI's Smart Function Modules provide uniquely flexible, mix & match customization options for use with our COTS hardware. Learn More

Module CM1

The CM1 module is a combination of NAI's MIL-STD-1553B module, FT2, and Enhanced Discrete I/O module, DT4. The CM1 offers twelve channels of discrete I/O and two channels of MIL-STD-1553B communications. The twelve discrete I/O channels are programmable as either input (voltage or contact sensing with programmable, on-module pull-up/pull down current sources), or output (current source, sink, or push-pull) up to 500 mA per channel from an applied, external 3-60 VCC source. The discrete I/O channels also provide additional functionality modes such as Pulse Width Modulation (PWM) output mode and Pattern Generator output mode. The two MIL-STD-1553B communications channels feature a dual, redundant, balanced-line, physical layer; a (differential) network interface; time division multiplexing; half-duplex command/response protocol; and up to 31 remote terminals (devices).

Discrete I/O Features

  • 24 channels available as inputs or outputs
  • Programmable for Input (voltage or contact sensing) or Output (current source, sink or push-pull) per channel/bank
  • Ability to current share, by connecting multiple outputs in parallel, to sink/source up to 2 A per bank
  • Ability to handle high inrush current loads (for example, two #327 incandescent lamps in parallel)
  • Supports "dual turn-on" (series channel output) applications (for example, dual series "key" missile launch control)
  • Pulse Width Modulation (PWM) output mode
  • Pattern Generator output mode
  • Timing measurement of inputs with 10 μs resolution
  • Programmable debounce circuitry with selectable time delay eliminates false signals resulting from relay contact bounce
  • Built-in test runs in background constantly monitoring system health for each channel
  • Ability to sense broken input connection and if input is shorted to +V or to ground
  • Ability to read I/O voltage and output current for improved diagnostics (indicates if load is connected)

MIL-STD-1553B Features

  • Independent (dual-redundant) MIL-STD-1553 interface channels:
    Bus Controller (BC), Remote Terminal (RT), and Bus Monitor (BM)
    operation
  • Support for RT and BM combination
  • 64 words on-board memory/channel
  • IP-core register-compatible with DDC™ family of devices
  • Automatic message return supported
  • Automatic message retry
  • Multiple message processing
  • Hardware acceleration for rapid setup/message Tx/Rx
