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

Combination Module - CM1

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

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

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

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
