PC-MAXI PC ISA Interface Card

PC-MAXI Multi-Adapter eXtender Arinc 429 Interface Card

The PC-MAXI has four module sites available for interfaces. It can support either similar or different interface types. So it is possible to have an ARINC429 2 transmit, 2 receive Mini-Module mounted on one site with a PANAVIA Mini-Module mounted on a second site, thus providing a mixed ARINC429 and PANAVIA solution.

The PC-MAXI (Multi - Adapter - eXtender - Interface) provides by far the most flexible platform for today's demanding test and OEM applications. 

The card features a common clock for all time tagging registration of data and single generation of PC interrupts from the various modules fitted to the card and provides a common master platform for all types of data bus interface that need to be interfaced to a PC.

The card is a full length PC ISA interface card designed to accept up to four standard YED Mini-Module Interface cards. 
Support for ARINC419/429/575, PANAVIA, NMEA0183 and opto-coupled discrete I/O are currently available. 
For example, the card shown is a 8 transmit and 8 receive independent (non-multiplexed) ARINC429 (16) channels.
In addition to this special interface application modules can be designed to order. Supplied with 'C' driver library source code.

Interface Configurations and Functional Characteristics

A common clock is available to all Mini-Modules, thus providing synchronized operation of features such as time tag registers. Interrupts generated by each Mini-Module are handled by the on card Interrupt Control Logic, which in turn is responsible for generating the PC interrupt. 
An Interrupt Status Register identifies the interrupting Module.

The card is configured as a 16 bit ISA interface and occupies the D0000 to DFFFFH PC Memory page space. Interrupts provided are 3,4,5,6,7,10,11 and 12.

Interface Module Types MINI-MODULES

MINI-429/T2/R2

MINI-429/T4

The MINI-429/T4 ARINC 429 Interface comprises of four independent transmitter channels that act as Bus Traffic Simulators. The functions on the four channels are available concurrently at full performance level. 
The card contains a microprocessor, Dual Port and ARINC429 line drivers. 
The specification is similar to the PC4/T4 PC ISA card.

MINI-429/R4

The MINI-429/R4 ARINC 429 Interface comprises of four independent receiver channels that provide 
advanced Monitor and Analyzer functions. 
The functions on the four channels are available 
concurrently at full performance level. 
In addition to this the card also contains, a microprocessor, a time tag register, Opto-coupled inputs, Auto-Rx Speed Adaption, Data Acquisition FIFO's, and Dual Port. 
The card will filter from all 256 label/SDI combinations. The specification is similar to the PC4/R4 PC ISA card.

MINI-NMEA0183

The MINI-NMEA0183 Interface comprises of a single channel NMEA0183 transmitter and receiver circuit. All received data is time tagged and written to the on board data acquisition FIFO’s in the order of arrival. Sentences can also be loaded and transmitted from the card at varying repetition rates at 4800 baud.

‘C’ source code driver libraries are also available for OEM’s that wish to implement their own software.
