A: Yes it does. In June 2012 extensive EMC tests have been performed on
the SPEC with a digital I/O (FMCDIO5chTTLa) card. These tests have been
made by AT4 wireless, a testing
laboratory accredited by the Spanish National Accreditation Body (ENAC
-Entidad Nacional de Acreditación) to perform the tests indicated in the
Certificate No. 51/LE 203.
The test report is publicly
available and shows that the card has passed the most restrictive EMC
tests of each class (domestic and industrial) successfully:
EM Radiated Emission: Class B (Domestic) EN 55022 (2006) / A1 (2007)
EM Immunity (Industrial): EN 61000-4-3 (2006) / A1 (2008) / A2
(2010), EN 61000-4-4 (2004) / A1 (2010) / Corr (2010), EN 61000-4-6
(2009), EN 61000-4-2 (2009), EN 61000-4-8 (2010).
Q: What are the differences between V1-0, V1-1 and V2-0?
A: V1-0 and V1-1 have different output buffers (SN74LS125 vs
SN74LVT125). This was the result of a mistake in the PCB library. V2-0
has improved I/O protection circuit which works when the card is not
powered. V1-0/V1-1 PCB designs are identical, in order to identify the
version, check the types of buffers soldered (IC2, IC5).
