3: VAM-CM Overview
Figure 2. VAM-CM
Due to the simple and compact interfaces, testing and evaluation of the VAM-CM requires interface
extension to enable easier access to control and indication signals. The VAM-CM Evaluation Module
available from Inmarsat provides easier and more convenient interfacing to the VAM-CM during
terminal test and evaluation phases.
3.2.1:Evaluation module
The Evaluation Module is intended for VAM terminal product HW and SW development and extracts
the VAM-CM control and SIM card pin header interfaces to standard interfaces as well as providing
some system setting possibilities.
Evaluation module and control software are described in more detail in Evaluation tools on page
