RMCU Installation
1. Insert the RMCU (component side facing right) into the appropriate slot, and apply firm, even 
pressure to ensure proper seating of the connectors. 
2. Gently pull the unit outward. If the connectors are properly seated, a light resistance is felt.
3. Wire the RCMS jacks, J4 and J5, to the network CAMA trunks per Figure 8-26 on Page 8-27.
4. Test the CAMA trunk and set the 3-dB PAD switches, SW101 and SW 201, for the appropriate 
volume level.

Universal Slot PCB Wiring8
This chapter contains point-to-point wiring diagrams for connection of telephones, lines, 
peripheral equipment, and power supplies for the universal slot PCBs of both the Strata DK40i 
Expansion KSU and DK424 systems.
Wiring diagrams are divided into groups according to the PCB which provides the interface for, or 
controls the operation of, the associated equipment, as listed below:
©Station Wiring:
©Digital Stations
©Electronic Stations
©Attendant Consoles
©Analog Stations
©Power Failure Cut-through (DPFT) Pin-outs
©CO Line Wiring
©DID and Tie Line Wiring
©Option Interface PCBs
NoteBefore using the Connect Record Sheets (following each Wiring Diagram), make copies 
for future use.
Diagrams which apply to only one system (e.g., DK40i) are in the installation chapter which 
relates to the system. Wiring diagrams appear at the end of these two chapters:
©Chapter 1 – DK14 Installation 
©Chapter 2 – DK40i Installation
The RDTU cable connection information (DK424 only) is in Chapter 6 – DK424 T1.
