Utility I/O Connectors
A number of interfaces on the EBX-22 are grouped together and made accessible through utility
I/O connectors J14, J15, and J23. Cables and boards are available from VersaLogic that provide
discrete connectors for each of the interfaces; however, you can create custom cables that surface
only the interfaces required by your application.
J14 I/O C
ONNECTOR
The 50-pin I/O connector (J14) incorporates the COM ports, PS/2 keyboard and mouse,
programmable LED, reset button, soft power reset, and speaker interfaces. Table 5 illustrates the
function of each pin.
