4-port serial interface:

On 1st July, 2006 the RoHS-Directive comes into force in Germany, which aims to reduce damages to environment and health by banning certain hazardous substances in electrical and electronic equipment.
As we switch to more eco-friendly products, a few of the oder boards will be discontinued. However, as substitute we have been developing comparable - and often more efficient - follow-up products.

As follow-up product for the APCI-7500 we recommend you the communication board APCI-7500-3, which will be the same reliable and interference-free partner for you as the APCI-7500, but with additional facilities.
Interested? - More information about the follow-up board APCI-7500-3: here
