Abaco Systems / SBS ABI-PMC2-1 MIL-STD-1553 Single Channel Interface

The Abaco Systems SBS ABI-PMC2-1 is a single-channel MIL-STD-1553 interface card designed for embedded systems that utilize the PCI Mezzanine Card (PMC) form factor. This interface card is engineered to support system-level applications and is available in various configurations, including commercial, extended temperature, and conduction-cooled versions. The ABI-PMC2-1 allows for concurrent and independent operation as a Bus Controller (BC), one of 31 Remote Terminals (RTs), or a dual-function Bus Monitor (BM).

### Technical Specifications

* **MIL-STD-1553 Channels:** 1 or 2 channels (the ABI-PMC2-1 specifically refers to a single channel configuration, though the ABI-PMC2 series supports dual channels).
* **Functionality:**
* **Bus Controller (BC):** Supports programmable frame lists, BC-RT, RT-BC, and RT-RT message types, mode codes, broadcasts, and time delays. It also features minor frame timing and message scheduling, intermessage gap selection, programmable delay gaps, null BC blocks, and multiple BC data buffers in a linked list structure.
* **Remote Terminal (RT):** Supports 31 RTs and all subaddresses. Features include RT level protocol selection, RT definition tables, programmable response time, no-response selection, and no-response time-out. It also supports multiple RT data buffers in a linked list structure.
* **Bus Monitor (BM):** Supports map monitoring and sequential monitoring. Map monitoring allows for multiple linked buffers per transmit/receive subaddress, read by the host processor as time permits. Sequential monitoring offers 100% independent operation with double-buffered messages that are time-stamped with a 1 µs 32-bit clock or an optional 48-bit IRIG-B clock. Both modes perform broad error monitoring and provide a comprehensive error table accessible by the host processor.
* **Architecture:**
* Utilizes a high-speed DSP, programmable logic, and dual-port RAM.
* On-the-fly data structures with BC and RT linked lists.
* Flexible memory structure.
* Flash memory for on-board firmware storage.
* The ABI interface architecture provides concurrent and independent operation.
* **Memory:** 256 kB of dual-port RAM. Some sources mention 1 MB of dual-port RAM per channel for the ABI-PMC3 series.
* **Bus Interface:** IEEE P1386 compliant PMC connection. Supports PCI bus 2.1 compliance with a maximum transfer rate of 132 MB/sec, 16-bit and 32-bit transfer modes, and 5V and 3.3V signal levels. Programmable DMA controller is available.

### Electrical

* **Power Consumption:**
* Single channel: 5 V @ 1.5 A (98% bus activity), 1.0 A (Bus Inactive).
* Dual channel: 5 V @ 2.12 A.

### Interfaces

* **MIL-STD-1553:** Single channel, dual redundant. Supports MIL-STD-1553A/B selections.
* **Optional Interfaces:**
* 4 Channels of RS-422.
* 28 Channels of Discrete I/O.
* 48-bit IRIG-B clock input.
* **Connectors:**
* 50-pin SCSI to coupling harness.
* BJ77F Triax connector to 1553 bus.
* DB I/O Connector.

### Physical

* **Form Factor:** PCI Mezzanine Card (PMC).
* **Dimensions:** Standard PMC card: Length 6.0”, Width 2.9”.
* **Weight:** Ranges from 2.44 oz to 3.84 oz. Specific weight for ABI-PMC is listed as 3.24 oz.

### Compatibility

* **Operating Systems:** Complimentary drivers available for most operating systems.
* **Software:** Integrated Avionics Library with source code is provided. Compatible with Borland and Microsoft® C Compilers.
* **Standards:** IEEE P1386 compliant. Compatible with VITA/ANSI-20-199x (Draft 1.6).

### Environmental

* **Temperature Ranges:**
* Level C (Standard Commercial, air-cooled): 0° C to +70° C.
* Level R (Rugged, forced air): -40° C to +85° C.
* Level N (Rugged, conductive cooled): -40° C to +85° C.
* Extended Temperature versions are available.

### Self-Test and Diagnostics

* Power-up test with status register report.
* Built-in RAM and encoder/decoder test.
* Run-time health status register.
* Unit Test application for 1553 bus functionality.
