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.

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.

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.
