2.3 Install Expansion Board
Some installations may require the optional 3x8
Expansion Board. Follow these steps to install the
3x8 Expansion Board in the KSU.
1) Connect the grounding wrist strap to an
approved ground.
2) Remove the 3x8 Expansion Board and stand-
offs (mounting posts) from the anti-static bag.
3) Remove the three mounting screws from the
installed 3x8 Interface Board and replace with
the standoffs. (Do not overtighten.)
4) Remove the two screws retaining the KSU side
panel insert and carefully remove the insert.
5) Align the 3x8 Expansion Board over the stand-
offs with the amphenol connector facing the
opening in the KSU side panel.
6) Carefully place the 616 Expansion Board on
the standoffs and secure with the screws
removed in step 3.
7) Connect the ribbon cable from the 3x8 Expan-
sion Board to connector JP3 on the KSU main
PCB.
8) Replace the KSU cover and secure with the
four cover screws.
2.4 Install KSU
The KSU can be mounted on a wall by attaching it to
the 3/4 inch wooden backboard used for the MDF.
See the section on "Install MDF" discussed previ-
ously. Follow these steps to mount the 616 KSU.
1) Unfold the mounting template and place it on
the backboard. The template can be taped on
the backboard for positioning.
2) Mark the location of the two mounting screws
on the template.
3) Remove the template and drill pilot holes for
the mounting screws.
4) Screw the hex head screws into the two pilot
holes for the mounting screws. Leave a 3/4 inch
gap between the screw head and the backboard.
5) Position the KSU so that the keyhole slots in
the mounting brackets are aligned over the
mounting screws. Press the cabinet in place
and lower to engage the brackets.
6) Once the KSU is on the MDF, pull the KSU cab-
inet gently outward to ensure that there is not
too much space between the KSU backing
plate and the MDF. If there is, remove the KSU,
tighten the mounting screws a little and
replace the KSU. Repeat step 6.
