SUPER I/O
Three display interfaces (mini DisplayPort, VGA, and LVDS) support up to two
independent displays, along with stereo audio. Communication interfaces include two
Gigabit Ethernet (Intel i210) ports, eight USB 2.0 ports, and four serial RS-232/422/485
channels. 48 digital I/O lines are individually programmable for input, output, or
interrupt-driven applications. The first 24 lines are capable of fully latched event sensing
with software-programmable polarity. For additional flexibility, the I/O lines can be
paired with external isolation and relay modules.
The EPX-C414 provides an upgrade for existing PC/104-Plus compatible single board
computers. Its designed for harsh environments and reliability, with an optional
solution for operating temperatures between -40 and +85°C (-40 and +185°F).
