4 Introduction

PMAC2 General Purpose I/O Use: This section describes the JIO port’s 32 discrete digital I/O lines

and provides information for configuring them individually for input or output using an inverting or non-

inverting format.

Using the Position Compare Feature on PMAC2: This section explains the position compare feature

on PMAC2 and describes how it provides a very fast and very accurate compare output function based on

the actual position counter.

Using the PMAC2 to Interrupt the Host Computer: This section describes the procedures that allow

PMAC2 to interrupt the host computer over the PC bus using any of eight built-in programmable interrupt

controller (PIC) signals.

Safety Summary

The following are general safety precautions not related to any specific procedures and therefore may not

appear elsewhere in this publication. These are recommended precautions that personnel must understand

and apply during many phases of operation and maintenance.

Keep Away From Live Circuits

Do not replace components or make adjustments inside equipment with power applied. Under certain

conditions, dangerous potentials may exist when power has been turned off due to charges retained by

capacitors. To avoid casualties, always remove power and discharge and ground a circuit before touching

it.

Live Circuit Contact Procedures

Never attempt to remove a person from a live circuit with your bare hands. To do so is to risk sure and

sudden death. If a person is connected to a live circuit, the following steps should be taken:

1. Call for help immediately

2. De-energize the circuit, if possible.

3. Use a wood or fiberglass hot stick to pull the person free of the circuit.

4. Apply cardiopulmonary resuscitation (CPR) if the person has stopped breathing or is in cardiac arrest.

5. Obtain immediate medical assistance.

Electrostatic Sensitive Devices

Various circuit card assemblies and electronic components may be classified as Electrostatic Discharge

(ESD) sensitive devices. Equipment manufacturers recommend handling all such components in

accordance with the procedures described in Appendix A. Failure to do so may void the warranty.

Magnetic Media

Do not place or store magnetic media (tapes, discs, etc.) within ten feet of any magnetic field.
