RAM PCTOOLS 400 program was developed to give the DATATRAC 400 user the capability of customizing the DATATRAC s firmware to meet special requirements Three aspects of the DATATRAC s firmware can be customized namely transmit data tables system setup tables and engineering format scaling definitions The output of PCTOOLS 400 us a 125K binary file containing the user defined data as well as other code and data required by the DATATRAC 400 The operator can then burn the binary file into a 27C101 1024 bit type PROM with a PROM programmer not supplied Transmit Data Tables The DATATRAC 400 has the capability of invoking previously defined data tables for transmitting on the ARINC 429 bus Typical applications might include routine test procedures where multiple transmit tables are repeatedly used Instead of the operator entering the labels from the keypad each time the operator can call up different data tables with just a few keystrokes This feature is particularly useful of the data tables are numerous or extensive as it greatly minimizing testing time and the chance for error on data entry System Setup Tables Some procedures may require fairly complex DATATRAC 400 system setups to accomplish a desired test There may be for example several dynamic transmit label definitions as well as some user defined formats that are used for a particular test Similar to the transmit tables the DATATRAC 400 provides for calling up predefined

100. TATRAC 400 provides a transmit framing feature that permits the operator to control the timing of multiple label transmissions This is useful for simulating LRU s that output several labels at different time intervals A brief explanation of the DATATRAC s method of framing labels of varying transmit periods is helpful for taking full advantage of this powerful feature Figure 4 illustrates the relation between a frame and a cycle There are always 60 frames in each cycle The frame and thus the frame period is defined by the fastest label on the channel For example if label 100 was set up with a 50 ms interval and all other labels were 200 ms the frame period for this channel would be 50 ms If a new label is defined with an interval of 10 ms the frame period would change to 10 ms Given the base minimum interval all other labels intervals must be one of the following multiples of the base 1 2 3 4 5 6 10 12 15 20 30 or 60 For example if the minimum interval is 50 ms other labels in the channel are permitted to have only the following periods 50 100 150 200 250 300 500 600 750 1000 1500 and 3000 ms If a label is specified with an interval that does not fall on one of the allowed multiples its interval will be adjusted to the nearest allowed rate Note that the display will still indicate the rate entered by the user but will transmit at a different rate Say in the above example that a label is defined with a rate o
