CAUTIONARY NOTES

1) Electrostatic Discharge (ESD) prevention measures should be used when handling this
product. ESD damage is not a warranty repair item.

2) Axiom Manufacturing does not assume any liability arising out of the application or use of
any product or circuit described herein; neither does it convey any license under patent
rights or the rights of others.

3) EMC Information on the DEMO9RS08KB12 board:
a) This product as shipped from the factory with associated power supplies and cables,

has been verified to meet with requirements of CE and the FCC as a CLASS A product.

b) This product is designed and intended for use as a development platform for hardware

or software in an educational or professional laboratory.

c) In a domestic environment, this product may cause radio interference in which case the

user may be required to take adequate prevention measures.

d) Attaching additional wiring to this product or modifying the products operation from the

factory default as shipped may effect its performance and cause interference with
nearby electronic equipment. If such interference is detected, suitable mitigating
measures should be taken.

TERMINOLOGY

This development module utilizes option select jumpers to configure default board operation.
Terminology for application of the option jumpers is as follows:

Jumper – a plastic shunt that connects 2 terminals electrically
Jumper on, in, or installed – jumper is a plastic shunt that fits across 2 pins and the shunt is

installed so that the 2 pins are connected with the shunt.
Jumper off, out, or idle – jumper or shunt is installed so that only 1 pin holds the shunt, no 2

pins are connected, or jumper is removed. It is recommended that the jumpers be placed
idle by installing on 1 pin so they will not be lost.

Cut-Trace – a circuit trace connection between component pads. The circuit trace may be
cut using a knife to break the default connection. To reconnect the circuit, simply install a
suitably sized 0-ohm resistor or attach a wire across the pads.

Signal names followed by an asterisk (*) denote active-low signals.
