... Full Military (-55°C to +125°C) Temperature Range • DESC SMD# Pending 1 The ACT3492 Series is a monolithic implementation of the MIL-STD-1553B Bus Controller, Remote Terminal and Passive Monitor functions including dual low power Bus tranceivers. All protocol functions of MIL-STD-1553B are incorporated and a number of options are included to improve flexibility. These features include programming of the status word, illegalizing specific commands and an independent loop back self-test which is initiated by the subsystem ...

REMOTE TERMINAL OPERATION Receive Data Operation All valid data words associated with a valid receive data command word for the RT are passed to the subsystem. The RT examines all command words from the bus and will respond to valid ...

... This is because much of their use is optional, and also because some involve only the RT while others involve both the RT and the subsystem. The ACT3492 allows full use to be made of all the Status Bits, and also implements all the Mode Commands. External programming of the Terminal Flag and Subsystem Flag Bits plus setting of the Message Error Bit on reception of an illegal command when externally decoded is available ...
Page 7
All other Mode Commands are serviced internally by the RT. The Terminal Flag and Message Error Status Bits and BIT Word contents are controlled by the RT; however the subsystem has the option to set the Message Error Bit and ...
Page 8
... OPTIONAL STATUS WORD CONTROL Message Error Bit The ACT3492 monitors all receptions for errors and sets the Message Error Bit as prescribed in MIL-STD-1553B. The subsystem designer may, however, exercise the option of monitoring for illegal commands and forcing the Message Error Bit to be set. ...

Terminal Flag Bit This bit is reset to logic zero by a power up initialization or the servicing of a legal mode command to reset the remote terminal (code 01000). This bit can be set to logic one in the ...

... The command word is transmitted down the bus. The TX/RX bit is, however, considered as being its inverse and transmit command is sent (Figure 21), the ACT3492 in BC mode believes it has been given a receive command. As the RT returns the requested number of data words plus its status, the BC carries out a full validation check and passes the data into the subsystem using DTRQ, DTAK, H/L, IUSTB and CWC operation ...

The monolithic circuit includes all circuitry required to perform the self-test. Self-test can be an on-line or off-line function which is initiated by simple subsystem intervention. The DRVINH signal selects on-line or off-line testing. accessing the MIL-STD-1553 data ...
