Electrical Installation 21
Note: 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 23).
Note: 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 22).
Four-Section Models
BA-2026 & BA-2028
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 24. Additional panels may be opened 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 it 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.
