PEKU Configuration to Support an HDSS Console Option
1. Set the SW1 switch to DSS.
2. See “HDSS Console” on Page 5-24 for console installation instructions. Each HDSS
console requires dedicated use of circuits 7 and 8 of a particular PEKU PCB.
PEKU Installation
1. Make sure the PEKU has been configured for the appropriate hardware options. See
“PDKU2 Hardware Options” on Page 3-4 for more information.
2. Insert the PEKU (component side facing right) into the appropriate slot, and apply firm,
even pressure to ensure proper mating of connectors. (For DK40, the PEKU can be
installed only in place of the RSTU2 or PDKU. See Chapter 1 – DK40 Configuration.)
3. After installing the PEKU, gently pull the PCB outward. If the connectors are properly
mated, a slight resistance will be felt.
