INTRODUCTION

The Remote Thumbwheel I/O PCB

(TWIO) adds I/O capability to a Remote I/O

Controller LAN Node PCB (RIO) in a

MicroTrac DSD system. The TWIO is con-

nected to the RIO through use of an I/O

expansion bus. Upon power-up, the RIO

will realize that the TWIO is present, and

begin utilizing the added I/O.

This document explains the hard-

ware of the Remote Thumbwheel I/O PCB

(TWIO) and how to utilize its I/O capability.

HARDWARE DESCRIPTION

POWER REQUIREMENTS

The power connector on the RIO is

used to supply the RIO and the Remote I/O

PCBs with power. The RIO supplies power

to each of the Remote I/O PCBs through the

I/O expansion bus. The power require-

ments for each of the voltages connected to

the RIO, therefore, include the power drawn

by the RIO and the power drawn by each of

the Remote I/O PCBs.

In order to select a properly sized

power supply, the current (I) requirements

of the PCBs for each of the voltages must be

known. The I requirements for the TWIO

are as follows:

I for +5 VDC = (I of TWIO) + (I of external

loads)

= (223 maA) + (0 mA)

I for +15 VDC = (I of TWIO) + (I of external

loads)

= (0 mA) + (0 mA)

I for -15 VDC = (I of TWIO) + (I of external

loads)

= (0 mA) + (0 mA)

I for +24 VDC = (I of TWIO) + (I of external

loads)

= (108 mA) + (0 mA)
