User Interface (USER)
The user interface, located on the rear panel of the ESIB, is a 25 pin Cannon connector which provides
access to the two user ports (Port A and Port B). Each port is 8 bits wide (A0 - A7 and B0 -B7) and can
be configured either as output or as input. The voltage levels are TTL levels (Low < 0,4 V, High > 2 V).
In addition, an internal +5 V power supply voltage is provided. The maximum load current is 100 mA.
The pin assignments for the USER connector can be seen in the following diagram:
