A Military Computer with Flexibility

A Military Computer with Flexibility

The TMS4705 is a 4U rackmount MIL-STD military computer with flexible MIL-DTL-38999 and MIL-STD-1553 rear I/O connector configurations designed for customer-defined applications.  These sealed connectors, plus front and rear-panel air filters, enable TMS4705 certification to various MIL-STD-810G and MIL-STD-461F standards and test methods.  The TMS4702 base system certifications allow the TMS4705 to be deployed with confidence in many challenging government & defense applications.  A rugged, lightweight aluminum chassis is utilized with a corrosion-resistant coating applied to both the chassis and fastening hardware.


Both long-life embedded motherboards manufactured by Trenton, as well as extended-life Intel® motherboard options, maximize application flexibility and performance by using COTS long-life components that support extended system deployments.  This fully designed and built in the U.S. rackmount computer enables extended PCI Express and PCI-X/PCI option card support in any military computing application.
