The PC401 is a full-featured, high performance, Dual Redundant MIL-STD-1553 serial bus Simulator Analyzer Tester designed as a plug in card for PCMCIA backplane. The PC401 includes full error injection and can operate in independent or simultaneous mode as a Bus Controller, multiple simulated Remote Terminals and full/selective Monitor. Its data structure can be changed on the fly without interrupting the processor for real time operation. The active monitor stores bus traffic in a monitor Buffer. Stored messages are time tagged and annotated with the bus message type and any detected errors. Stored words are annotated with a break down of the word error.
The PC401 can be used for Validation Testing, Production Testing, full bus simulation and monitoring, as a general purpose 1553 interface or a stand alone bus Analyzer. For precise message scheduling and measurements, the Major and minor frame times are independent of message sequences or retransmissions on errors and the start of all command messages are independent of message length, response time or length of response. Message timing is calibrated and RT responses have low jitter.

The PC401 comes with software drivers for DOS and Windows XP/.2000. A set of well documented API’s with Source code written in "C" is included.
A menu driven user interface is included for stand-alone operation. With this program the user can set up 1553 traffic, simulate RT'S responses, monitor all or selected traffic in real time and capture data using trigger and search arguments.
The PC401 data filter looks at the complete command rather than just addresses and sub addresses. The user designates individual Messages to be ignored, monitored, replied to or monitored and replied to.
The PC401 processes 1553 messages with a minimum attention from the CPU. The user need only write a set of command Blocks, a message list and number of messages to define a minor frame of 1553 messages. He writes a minor frame time, the number of minor frames per major frame and a minor frame list to define a major frame. The bus controller sends the major frame a number of times as programmed in the major frame count, without any further attention from the CPU.
In the Remote Terminal mode, the user writes a set of command Blocks, and a look-up table for the PC401 to respond autonomously to incoming messages. In both modes an active monitor analyzes, annotates and stores bus traffic in a monitor Buffer.
The PC401 generates ten interrupt flags to show completion of a frame in the BC mode, receipt of a specified message, receipt of a specified Data word, receipt of a specified Status word, detected message errors or triggers.
- Direct coupling
- Transformer stub coupling
The PC401 operates as a 16 bits, auto Indexing, Dual ported static RAM. An auto incrementing address register serves to hold the initial RAM Address and increments after each data transfer. Two additional registers control the mode of operation.
Both the registers and the RAM can be loaded with new data while a message is being transmitted over the 1553 channel for real time applications. Essentially, programming the PC401 consists of transferring data to or from the RAM.
