Printed Circuit Board (PCB) Installation
DK40 Installation
Strata DK40 I&M Manual Spring 1999
2-23
Refer to the Strata DK40 Programming Manual or DK Library CD-Rom for more details.
PCB Hardware Options
Each PCB must be configured for the applicable hardware options prior to installation of the
PCB. Configuration instructions for internal hardware options are provided in the individual
PCB installation procedures in this chapter and Chapter 4–DK40 Universal Slot PCB Wiring.
Configuration instructions for external hardware options are provided in Chapter 6–
Peripheral Installation.
PCB Software Options
After installation of the PCBs in the KSU, configure the PCBs for software options through
programming. A programming overview for each PCB is provided in this chapter. Refer to
the Strata DK40 Programming Manual for more detailed programming instructions.
PCB Installation/Power Supply Considerations
Before installing any PCBs, make sure the power supply has been tested, and the earth has
been checked. (See “AC Power and Earthing Requirements” on Page 2-4.)
PCB Wiring
See Figure 2-28 in this chapter for DK40 Base KSU wiring and Chapter 4 – DK40 Universal
Slot PCB Wiring for Expansion KSU wiring.
Digital Telephone Circuits
The eight digital telephone circuits that come standard with the system are integrated into the
DK40 motherboard in the Base KSU. These circuits are identical to the digital circuits found
on the PDKU. The motherboard does not have to be configured for the digital circuits to
operate. For wiring see Figure 2-28.
WARNING! To avoid electrical shock, make sure that the power supply is
OFF whenever removing or installing PCBs.
