7.5.6.3 Using Multiple Expansion Panels (KP-12 Only)
When using multiple expansion panels, some MOD numbers may have to be reassigned so that
each group of 4 keys has its own unique MOD number. Table
5 shows the correspondence between
MOD numbers, key numbers, and setup pages.
Example 1, connecting one EKP-20 along with a KP-12: Use the default MOD numbers as
shown in Table
4. Next, assign setup pages. See “TOP LEVEL MENU, PAGE”, page 25.You
should assign one setup page as MAIN. This page will correspond to the keys on the KP-12. As-
sign a second setup page as “Exp1”. This page will correspond to the first 16 keys on the EKP-20.
Assign a third setup page as “Exp2”. The first 4 keys on this setup page will correspond to the re-
maining 4 keys on the EKP-20. The remaining12 keys on the setup page are not used. If you want
to connect LCP’s, you can use one LCP-12 and one LCP-20 without changing the ROMs.
Example 2, connecting two EKP-20 Expansion Panels along with a KP-12: From Table
4 you
can see that the EKP-20 has default MOD numbers 5 through 9. One of the EKP’s must therefore
be reprogrammed to use MOD 10 through 14. Also, assign one setup page as “Main”. (To assign
setup pages, see “TOP LEVEL MENU, PAGE”, page
25.) This page will correspond to the keys
on the KP-12. Assign a second setup page as “Exp1”. This page will correspond to the first 16
keys on the first EKP-20. Assign a third setup page as “Exp2”. The first 4 keys on this setup page
will correspond to the remaining 4 keys on the first EKP-20. The remaining 12 keys on this setup
page will correspond to the first 12 keys on the second EKP-20. Assign the last setup page as
“Exp3”. The first 8 keys on this page will correspond to the remaining 8 keys on the second EKP-
20. The remaining 8 keys on the setup page are not used. If you want to connect LCP’s, you can
use one LCP-12 for the KP-12 and one LCP-20 for the first EKP-20 without changing the ROMs.
You will have to change the ROM in the second LCP-20, however, to match the MOD numbers for
the second EKP-20.
