• On the MS-2009 with red/amber digits, there will also be five 9-pin digit harnesses
( P11–P15 ) in the Bottom Section that must be routed up into the Top Section and
plugged into the mating jacks ( J11–J15 ) on the Primary Driver.
• For the BA-2025, BA-2027, BA-2125, and BA-2127, route the 5-pin interconnect cable
from the Bottom Section up into the Top Section, and connect the P42 plug to the
J42 jack coming from the Primary Driver ( Figure 26 ).

• For the BA-2027 and BA-2127, a separate wired signal (copper or fiber optic) must
be terminated to a small enclosure in the Top Section to control the speed of
pitch digits.
• For the BA-1518 with red/amber digits, there are five 9-pin digit harnesses ( P1–P4
& P15 ) in the Top Section that must be routed down into the Bottom Section and
plugged into the mating jacks ( J1–J4 & J15 ) on the Primary Driver. For the BA-1518
with white digits, there is a single 5-pin interconnect cable coiled in the Top Section
that must be routed down into the Bottom Section and connected to the J42A jack
on a Y-cable coming from the Primary Driver (refer to Figure 25 ).

Open the appropriate access panel on the bottom-left cabinet (Section C) to locate the
coiled bundles of interconnect cable coming from the driver, then route and connect
the cables as described below and shown in Figure 27 . Additional panels may be
opened as needed for easier access.
1� There are four 9-pin digit harnesses ( P8–P11 ) in the upper-right cabinet (Section B) that
must be routed into the upper-left cabinet (Section A) and connected to the mating
J8–J11 jacks on the Primary Driver.
2� There are also two separate interconnect cables in Section C:
a� Route the 5-pin interconnect cable with the P42 plug up into Section A, and
connect it to the J42 jack on the Primary Driver.
b� Route the 5-pin interconnect cable with the J43 jack over into the bottom-right
cabinet (Section D), and connect to another interconnect cable with the P42
plug.
Note: For the BA-2028, a separate wired signal (copper or fiber optic) must be
terminated to a small enclosure in Section A to control the speed of pitch digits.
