2 - Hardware Description

The UE9 has 3 different I/O areas:

• Communication Edge,
• Screw Terminal Edge,
• DB Edge.

The communication edge has a USB type B connector (with black cable connected in Figure 2-1), a 10Base-T Ethernet connector (with yellow cable connected in Figure 2-1), and two entry points for external power (screw-terminals or power jack).

The screw terminal edge has convenient connections for 4 analog inputs, both analog outputs, and 4 flexible digital I/O (FIO). The screw terminals are arranged in blocks of 4, with each block consisting of Vs, GND, and two I/O. Also on this edge are two LEDs associated with the two processors in the UE9.

The DB Edge has 2 D-sub type connectors: a DB37 and DB15. The DB37 has some digital I/O and all the analog I/O. The DB15 has 12 additional digital I/O.
