The CM-DS-40 is a general purpose S/R output VMEbus board, incorporating eight channels & features most demanded in first class military & industrial applications.
Input channels incorporate auto-conversion circuitry that fills a Dual port RAM with the latest conversion data. All I/O channels support most common S/R voltage ranges used in military and avionics equipment.
Incorporating Built-In-Test that is based on wraparound loops that disconnect external S/R signals and connect internal test signals in order to verify correct module operation.
The metallic layer within the PCB benefits heat dissipation & uniform component temperatures, thus increasing component longevity & module MTBF. All versions are compatible at the function level, Industrial versions allow low cost software development.
The CM-DS-40 offers a highly flexible I/O cabling solution using both the front panel & P2. Military versions with thermal overlay greatly improve capability to withstand shock & vibration.

* IMPORTANT - The user must fully specify the I/O range requirements when ordering any module. The basic ordering parameters are:
Wind River Systems VxWorks Tornado: The CM-DS-40 is supported by VxWorks Tornado & is ideal for developing real time software under UNIX environments. A complete "C" language driver in source code is available at low cost. Drivers include a floppy-disk & user's manual.
Generic "C" Language Driver: A generic "C" language driver is also available in source code. The user may freely adapt for any application, operating system or ANSI "C" compiler. This code has been successfully compiled with the well established Mentor Graphics toolset.
* NOTE - Drivers for other leading operating systems can be optionally supplied under request.
