3.4 How to upgrade the system
PC/104's ability to stack I/O and other modules to add functionality is a
key feature, ARK-4170 also uses special brackets on the aluminum
enclosure itself so that additional enclosures can be stacked making this
most flexible rugged solution on the market.
ARK-4170 can stack other PC/104 modules. One enclosure can stack up
to two PC/104 family cards, if the application needs more than 2 modules
then just add a second enclosure to extend the system space. Advantech
