Sample Application
shows a typical example of how to integrate an EMS31-V module with an application.
Usage of the various host interfaces depends on the desired features of the application.
Because of the high RF field density inside the module, it cannot be guaranteed that no self
interference might occur, depending on frequency and the applications grounding concept. The
potential interferers may be minimized by placing small capacitors (47pF) at suspected lines
(e.g. RXD0, or ON).

(e.g. RXD0, or ON).
While developing SMT applications it is strongly recommended to provide test points
for certain signals, i.e., lines to and from the module - for debug and/or test purposes.
The SMT application should allow for an easy access to these signals. For details on
how to implement test points see

The EMC measures are best practice recommendations. In fact, an adequate EMC strategy for
an individual application is very much determined by the overall layout and, especially, the po-
sition of components.

Note: EMS31-V is not intended for use with cables longer than 3m.

and the information detailed in this section. As functionality and compliance
with national regulations depend to a great amount on the used electronic components and the
individual application layout manufacturers are required to ensure adequate design and oper-
ating safeguards for their products using EMS31-V module.
