1.1. Mechanical

The DM-20 module has no mechanical elements other that the main PCB assembly. All critical
electronic components are shielded using sheet metal cans to prevent internal/external
electromagnetic interference from degrading the module’s performance and to prevent the
module from interfering with other nearby devices. The following figure shows a typical
mounting configuration of the module with the main motherboard assembly. The module is
plugged into the fixed mating connector and secured with four screws to the standoff
components.
