SECTION 1 - INTRODUCTION

OVERVIEW

The NTCU01 Serial Interface Termination Unit provides a ter-
mination point for a INSIM01 Serial Interface Module or
optionally to a IMSPM01 Serial Port Module. The NTCU01 ter-
mination unit has two DB-25 connectors so that a diagnostic
terminal (port one) and a computer or modem (port two) can
connect to it through RS-232-C cables. The serial interface ter-
mination unit (TCU) connects to the serial interface module
(SIM) or serial port module (SPM) through a termination cable.
Figure

shows an example of the TCU termination unit

being used to connect a diagnostic terminal to the SPM
module.

INTENDED USER

Technicians should read this manual before installing the TCU
termination unit. Do not put the TCU termination unit into
operation until you read and understand this instruction.

HARDWARE DESCRIPTION

The TCU unit mounts on a NFTP01 Field Termination Panel,
inside the INFI 90

®

cabinet. It is a printed circuit board that

consists of:

•

Two DB-25 connector sockets.

•

Cable connector.

•

Current limiting resistors.

•

Faston tabs for system common.

HARDWARE APPLICATION

The NTCU01 unit provides a place to connect two RS-232-C
communication cables from a computer, modem or diagnostic
terminal to the serial port module and the serial interface mod-
ule. It is a passive device that channels the communication sig-
nals to each module.

The INSIM01 module is part of the INPCI01 Plant Loop to Com-
puter Interface. It enables a host computer to communicate
with any node on the plant loop. Interface software enables the
computer to acquire data, do process monitoring, load control
strategies and configure modules.
