Jumper 3
Use this jumper to select the type of PC with which the KE18 will be
used.
With this jumper removed (the most commonly used setting), the
KE18 operates in the PS/2 “AT” mode, compatible with Pentium and
X86 computers.
When this jumper is in place, the KE18 will operate as a PCXT type
keyboard. This mode allows for compatibility with early PCs and PCXT
based single board computers.
