Multi Protocol 4000 Modules

The M4K module can be one of many protocols that is used on a variety of platforms for the 4000 Multi Protocol Board.


M4K1553Px & M4K1553PxS modules are compatible with all common variations of MIL-STD-1553 (A, B). Each M4K1553Px multi function module can operate simultaneously as a Bus Controller and up to 32 Remote Terminals and as a Triggerable Monitor. In addition, error injection (BC and RT modes) and error detection (all modes) are supported on each module.
Each M4K1553PxS single function (RT validated) module operates either as a Bus Controller, Remote Terminal, or Bus Monitor.


M4K1553MCH module supports both MIL-STD-1553A and MIL-STD-1553B protocols and may be programmed to operate as a Bus Controller, Remote Terminal, Bus Monitor, or Remote Terminal / Concurrent Bus Monitor. The 32K x 16 of RAM allotted to each module for the storage of data and control parameters may be updated in real time. ***NOW A LEGACY PRODUCT***


M4K1553Px(S)-1760 module is identical to the M4K1553Px(S) module but in addition, Checksum, SRQ bit and Header Words are supported.


M4KH009 module can operate as a Central Computer Complex (CCC) and/or up to 16 Peripheral Units (PUs) simultaneously, or as a Bus Monitor. In addition, a Concurrent Bus Monitor enables concurrent monitoring of the bus during CCC and PU simulation. The module also supports error injection and detection, and all control parameters and data may be updated in real time.


M4KMMSI module supports up to 8 MMSI hub ports and composite Bus Monitor output. Each module can operate in one of three modes of operation: Remote Terminal, Bus Controller/Concurrent-RT/Concurrent Monitor, and Bus Monitor.


M4K429RTx module supports up to ten ARINC-429 channels in any combination of transmitters and receivers. Each of these channels feature error injection and detection capabilities.


M4K708 module supports up to two ARINC-708/453 channels for the Weather Radar Display Databus. Each channel is selectable as transmit or receive and implements an 64K word FIFO and supports polling and/or interrupt driven operation.


The M4K717 is an intelligent ARINC 717 interface module for the multiprotocol Excalibur 4000
family of carrier boards. The module supports two ARINC 717 receive channels and two transmit


M4KSerial module supports up to four independent channels of serial communications, each of which can be selected as RS-485, RS-422 or RS-232. The module operates independently of the host computer, reducing the need for host intervention.


M4KDiscrete module provides a complete solution for developing and testing discrete voltage-level interfaces. The module contains control I/O registers that are memory-mapped and may be accessed in real time and supports twenty programmable I/O discretes that can record or control the external discretes that are connected to it.

825 CAN

The M4K825CAN is an intelligent multichannel ARINC 825 (CAN bus) interface module for the multiprotocol Excalibur 4000 family of carrier boards. The module supports up to ten ARINC-825 channels.


The M4K-ETH is an intelligent Gigabit Ethernet interface module for the multiprotocol Excalibur 4000 family of carrier boards. The module supports 10Mhz, 100Mhz and 1Ghz Full Duplex UDP/IP Ethernet.
