Revision 1.0
OVERVIEW
Add-On Module
To designate the meaning of the upper 24 keys on an Add-On Module, FKYs 17 through 40 of the D
term
that
works in combination with the DSS are used. The remaining 36 keys on the Add-On Module are assigned using
FKYs 5 through 40 of the original port of the Add-On Module. The relationship between KYN, which appears
in the AKYD command, and 60 keys on an Add-On Module is illustrated below. In Figure 1-9, an Add-On Mod-
ule is connected to LV 1 as an example.
