- High Integrity
- 4 Independently programmable Receive Channels
- 4 Independently programmable Transmit Channels
- Loop-back Test Mode
- Versatile Interrupt Facility
- 32-bit PCI interface
- 2 x 32-bit data cyclic buffers per channel
- Supports ARINC 568, ARINC 571 and ARINC 582
Sycos 6-wire ARINC-561 PMC Transmitter/Receiver module offers the user up to 4 Transmitter
and 4 Receiver channels on a single width PMC module.
Each channel is supported with a pair of Cyclic-Data-Buffers each of which are 1k
deep and 32bits wide configured as follows:
- 32-bit receive data word
- 32-bit receive timestamp word
- 32-bit transmit data word
- 32-bit transmit time gap word
Deeper buffers are available as an option.
ARINC Input/Output is via the backplane and also via a 68 pin SCSI connector on the
PMC module faceplate. Provision is made for a Connector Identification Code to be
read from the connector.
This product also supports the six-wire standards of ARINC-568, ARINC-571 and ARINC-582.
Firmware options are available to enhance the functionality of the product to realise
an extremely sophisticated simulation and testing facility. Refer to the product
data sheet for details.
The module provides configuration registers which allow the host to:
- Automatically identify the module and its revision status
- Identify connector cables connected to the card
- Assign address space for the card's data buffer memory and registers. (Plug-in
- Control and monitor the PCI bus interface to the card
- Read module interrupt configuration as assigned by the POST software as it initialises
and configures the system
Additional features designed into the module are:
- Independent Cyclic-Data-Buffer per channel, each with a capacity for 1k x 4 byte
- Direct access to the Cyclic Data Buffer Read / Write Pointers
- PCI interrupts on Module Events
- Direct access to Module registers and application memory
- Interface compatible with PCI Local bus Specification, revision 2.1, June 1995
The PMC module is designed to be used in a "Plug-in and Play" environment which is
made possible, not only by the choice of PCI interface, but also by the provision
of various identification and module present registers. These include:
- Device ID
- Vendor ID
- Subsystem ID
- Subsystem Vendor ID
- Connector ID / Present
- Module ID
Using these registers the host can detect the module presence, determine if this
is consistent with system requirements and respond accordingly by configuring the
system or reporting system deficiencies.
