When installing the KE11-E, you have to remove a jumper on the CPU's M7233 module. See pg. 2-1 on the KE11-E/KE11-F User's Manual (EK-KE11E-OP-001), available online. Did yours come with the three flat cable jumpers? If it's still not working, the KE11-E/KE11-F Technical Manual (EK-KE11E-TM-002), also available online, will undoubtly prove useful. Noel
