PMC handles huge I/O range
All of the M705's ARINC-429 channels comply with the AEEC adoptions of the ARINC-429 specifications and provide both high and low speed operation, 100 and 12.5kbps respectively.
Aitech Defense Systems has released a compact, multi-I/O PMC that provides a variety of configuration options for the highest levels of flexibility in different I/O environments The low-power, single-width M705 features an unprecedented level of PMC density with up to five dual channel, dual-redundant MIL-STD-1553B channels, 16 ARINC-429 receive channels and eight ARINC-429 transmit channels, up to six RS-232/422/485 serial channels and eight opto-isolated digital discrete input channels, all of which reduce the number of I/O cards when developing subsystems

VME SBC handles harsh-environment applications
The rugged new C106 single board computer is a VME64x-compliant solution featuring up to 1.5GHz of processing power and 4Gbyte of onboard NAND Flash memory.
Rugged enclosure seals in 6U systems
Comprehensive environmental protection for 6U VMEbus or CompactPCI single board computers is now available in the rugged, single-slot E118 chassis enclosures from Aitech Defense Systems.
Additional board options include an ARINC 708 Weather Radar interface contained as VHDL within the large on-board FPGA.
The number and range of channels available on the PMC, coupled with its power consumption of less than 7.5W and shock and vibration resistance, make the M705 suitable for a range of I/O applications.
These include tactical avionics platforms such as F-18 or V-22 mission computers as well as mission data recorders.
The MIL-STD-1553 (STANAG 3838) channels support BC/RT/MT operation modes and offer 128K byte (64K words) of dual-port RAM per channel.
All ARINC-429 channels comply with the AEEC adoptions of the ARINC-429 specifications and provide both high and low speed operation, 100 and 12.5kbps respectively.
The six UART channels feature a global interrupt source register and two of the channels can provide full modem flow control lines (RTS, CTS, DTR and DSR).
The discrete input channels serve as general purpose I/O ports that connect to the GPIO FPGA, but are primarily used to externally assign the RT address to the MIL-STD-1553 channels.
The M705 has a 32bit/66 MHz PCI 2.2 interface that supports both +5 and +3.
V PCI universal signaling levels.
The conduction-cooled version routes all signals to the rear P4 connector and the IEEE1386-2001 air-cooled version can be equipped with connectors for front panel I/O signal routing.
The PMC is available with a temperature range of -55 to +85C.
Software for the M705 includes a complete software driver package supporting all on-board resources and built in test (BIT), initially through the WindRiver VxWorks 5.x and 6.x operating systems.
