429EX

ARINC 429 DATABUSANALYZER

ReceiverOperation The unit is capable of receiving and trapping (storing) up to 255 highor low speed 32 bit words in 429 or 419 bipolar RZ format. The unit is also capable of trapping 511 occurrences of one professional label of data onlyfrom strings of data containing multiple words. The special triggertrap mode expands receiver capabilities further to allow trapping of block data protocols or of alphanumeric strings of data. The receiv- er also allows the user to view all individual bits. Receiver bus speedis switch selectable. Industrial lcd display of received labels is provided withselection of hexadecimal or engineering formats. Initial receiver screen professional displays the number of labels that have been received withability provided for stepping through each label for data display. Trapmode allows operator to select which labels are to be trapped (four possible user selectable label/data combinations). Access to receivedor stored data is accomplished by single-step scrolling keys or byautomatic scrolling mode. Trapped data is stored in non-volatile memory until cleared.

The easy method for troubleshooting ARINC 429 labels

The 429EX provides avionics technicians and line-maintenance personnel with an easy method fortroubleshooting ARINC 429 labels. It has thecapability to selectively trap labels three different ways. The 429EX has a non-volatile memory andfeatures user-selectable ARINC Air TransportEquipment Identifier Codes. Transmitted and received data can be viewed in either hexadecimalor easy-to-understand engineering format.The 429EX is housed in a rugged, compact casewith internal, rechargeable NiCad batteries. The unit comes with either a 110V or 230V plug-in bat- tery charger. An optional carrying case is availablefor convenience and protection of the unit. TransmitterOperation The 429EX provides capability for transmitting upto ten 32 bit words in ARINC 429 or 419 bipolarRZ format. The transmit bit rate can be set forhigh (100 kbps) or low (12.5 kbps) speed with selectable odd or even parity. The unit allows key-pad entry of transmit label (octal) with data entryvia hexadecimal (bits 32 through 9) or by engi- neering equivalent values. Entry by engineeringvalues allows individual entry of primary data(miles, knots, MHz, etc.), SDI, SSM, word rate and individual bit switching functions. Non-RF labels have additional screens that allow for slew-ing data with programmable slew limits and direc-tion of slew in desired increments. The transmit- ter operation is completely independent of thereceiver, allowing simultaneous operation of boththe transmitter and receiver. Transmitted labels can be stored in non-volatile memory.
