1. INTRODUCTION

1.1 PURPOSE OF DOCUMENT

This document describes the electrical interface for the ARIES Optical Head and sub-modules.

2. ELECTRICAL INTERFACE

2.1 CABLE INTERCONNECTIONS

ARIES modules interconnections are shown in the following diagram:

Figure 2–1 ARIES Cable Interconnections

2.2 PLACEMENT OF NEW CONNECTORS

Ethernet connector J125 and RS-422 connector J124 will be added to the Optical Head assembly. Detailed

design about connector placement is still open but Figure 2–2 below illustrates the baseline for the proposed

location. A bracket will be added at the top right corner of the Optical Head. It will hold J125 on its upper side

and J124 on its lower side.

2.3 SYSTEM CABLING EVOLUTION

Effort was made to minimize cabling modifications. Most of the cables will keep their actual configuration and

function, some will see their wires reassigned to other functions without modification. This is mainly the case for

signal and power cables.

The situation is not the same for communication cables. Optical fibers are replaced with an Ethernet

communication link, which is a completely new cable design. RS-422 link will connect between Scan

Electronics and optical head, requiring, once again, a new cable design. RS-485 communication link will no

longer exist between the PC and the Optical Head module. As RS-485 communication is only used during

temperature controller configuration, a dedicated connector will be mounted on the optical head and a special

interface cable will allow for device reconfiguration. A cap will close and protect the connector when not in use.

2.7 ETHERNET CABLE DESCRIPTION

The Ethernet cable will serve as communication link between the laptop PC and the ARIES system. All

command and data exchanges will travel through it, this will be the only link between the laptop PC and the

ARIES system.

The Ethernet connection will be made using a standard category 5e shielded crossover Ethernet cable, using

T568A to T568B wiring standard. The proposed PIC P/N E50824 cable proposed by the customer meets the

requirement. A RJ45 connector that provides shielded termination and connection must be used to allow for

proper cable shielding. This is generally the case for all metal body RJ45 connector.

The military style connector identified to be used on the Optical Head for J125 is of Amphenol RJF series. It

accepts simple RJ45 connector as well as compatible assembly of RJ45 and RFJ series plug. When mated

together, these connectors are sealed against fluids and dusts according to IP67 rating.

On laptop computer side no special connector assembly is required.

The following picture shows the Amphenol RJF series cable conversion approach:

Figure 2–4 below shows standard crossover Ethernet cable wiring, T568A to T568B standard. Shielded

connection is omitted for clarity.

2.8 RS-422 CABLE DESCRIPTION

The RS-422 link will serve as communication means between the Digital Control Module (new electronics,

located in the Optical Head module) and the Scan Electronics Box. All commands and status related to the

pointing mirror and the black bodies will travel through it.

ABB ARIES




Date: 4 July 2006 7

The RS-422 communication will take place over two, individually shielded, 100Ω twisted pair cables with

overall sheath. The cable assembly will link J124 to J159. Military type connectors will be used.

2.9 RS-485 CABLE DESCRIPTION

The RS-485 link will serve to verify and/or modify the set point of the temperature controller located in the

Optical Box. The cable described in this section is not intended to be used during normal system operation. A

cap will close and protect J108 on the Optical Head module during flight conditions.

When required, a communication link will be established with the interferometer internal temperature controller

using a special cable. This cable will include a RS-232 to RS-485 converter. A special software, already included

in the actual version of the instrument, is required to communicate with this controller.

The RS-485 communication will take place over a shielded 100Ω twisted pair cable. The cable assembly will

link J108 on the Optical Head module to a laptop PC’s serial port. Military type connector will be used on the

Optical Head side, while the RS-232 to RS-485 converter and its power supply will be installed on the other end

of the cable.
