PHYSICAL DESCRIPTION

The SVM2608 has a protective coating applied to it to ensure that the effects of environmental hazards are minimized. This coating endows the modules with resistance to salt sprays, moisture, dust, sand, and explosive environments, as the polymer coating provides a hermetic seal. The module is designed to withstand the stress and rigors of shock and vibration, allowing the module to be deployed in a variety of applications without concern for damage due to the surrounding physical environment. The following table details the environmental specifications of this module.

The SVM2608 has two indicator LEDs located on its front panel. The A/E (Access/Error) LED flashes green when read/write commands are being sent to the module. Should the SVM2608 receive an error, the LED glows red. This LED can be overridden by the user by setting the Sysfail bit in the Reset, Sys Fail Control, Interrupt Levels Register. The P/F (Power/Fail) LED glows green indicates the status of a processor driven self-test. If the self-test is successful, the P/F LED glows green, if the test fails, however, the LED will glow red. Both the A/E and P/F LEDs can be programmed to glow red when a fail condition occurs.
