General Features

The PC-MAXI (Multi - Adapter - eXtender - Interface) provides by far the most flexible platform for 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. It provides a common master platform for all types of databus interface that need to be connected to the PC ISA bus.

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 is currently available. For example, the card shown is a 8 transmit and 8 receive independent (non-multiplexed) ARINC 429 (16) channels. Special interface application modules can be designed to order.

The card is supplied with 'C' driver library source code.

Interface Configurations and Functional Characteristics

The PC-MAXI has four module sites available. It can support either similar or different interface types. For example, it is possible to have an ARINC 429 2 transmit, 2 receive Mini-Module mounted on one site and a PANAVIA Mini-Module mounted on a second site, thus providing a mixed ARINC 429 and PANAVIA solution on a single card.

A common clock is available to all Mini-Modules, thus providing synchronised 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 0xD0000 to 0xDFFFF PC Memory page space. Interrupts provided are 3, 4, 5, 6, 7, 10, 11 and 12.
