1. Introduction

The Fanout Interface provides connections between two magnet test stands and the PAFMS. To do this, the Fanout Interface includes the following connectors for each test stand:

* Harmonic Probe connector,

* Flat Probe connector,

* Probe ID connector, and

* Encoder connector.

The Fanout Interface also provides interconnections between PAFMS 's modules including:

* Coil Configuration Modules (CCM),

* Signal Integrator Module (SIM),

* Panel Interface Module (PIM), and

* Front End Modules (FEM).

The Fanout Interface is composed of an Fanout Interconnection (FIB) and Input Configuration (ICB) printed circuit boards.

The FIB constitutes the main part of the Fanout Interface and includes wiring needed to perform all external and internal connections.

The ICB provides direct connections from either Harmonic or Flat input connectors to CCM's input channels.

The Fanout Interface allows the system to be configured for measurement and test modes. System configurations for both modes are given in Figures 3 and 4.

2. Input Configuration Board

The ICB, shown in Figure 1, was designed to provide direct connection between Harmonic and Flat Probe inputs and CCM's input channels. This is done by connecting coils from the Harmonic input connector to CCM1 input channels and coils from the Flat input connectors to CCM2 input channels (see drawing number 1670-EB-329031 for the wiring details).

The wiring of the ICB is arranged with signal pairing so as to minimize cross talk between signals. Between each pair of signals runs a single ended shield trace that is referenced either to CCM1 or to CCM2 shield lines. The shield wires associated with CCM1 are connected to an inner plane referenced to pin 1 of connector J1. The shield wires associated with CCM2 are connected to another inner plane referenced to pin 39 of J1.

Fig. 1 Input Configuration Board Outline


Connector J1 is a Hypertronics 126 pin, 90 degree, gold plated, male connector with the part number KA126/127CPMC10TH. Its mating pins align with sockets on its female counterpart on the FIB. Care should be taken during insertion or extraction of these connectors since their life shortens considerably when forces are applied angularly.

Each ICB is defined by a serial number which is stored in a serial number device (SSN). The DALLAS 8-bit DS2400 part is used for this purpose.

Four jumper points JMP1 - JMP4 are provided to configure shield drivers for the FEMs. When all jumpers are open, both shields are driven by FEM's internal drivers (active driving). When JMP1 is connected to JMP2 and JMP3 is connected to JMP4 then the shields are connected to FEM1 and FEM2 analog grounds accordingly (passive driving).

3. Fanout Interconnection Board

The FIB is used to interface all Probe inputs and test inputs to the CCM modules. It also directs test signals from the Panel Interface Module (PIM) to the CCM modules. In addition the FIB provides a wiring interface for the SIM (Signal Integrator Module) and for encoder test signals. The FIB is a six layer printed circuit board measuring 3-1/2 x 12-5/8 inches. The FIB is laid out with connectors on both sides to aid in the distribution of cable connections. The FIB wiring is shown on drawing number 1670-EB-329030. See figure 2 for general layout.

3.1 Connector Functions

J1 is the Harmonic Probe Input connector. Nine Harmonic coil signals are wired from J1 to J10 on the printed circuit board. J1 also has a provision for probe identification. J1 is a 26 pin male MS style connector with a Jam-Nut mounting and printed circuit compatible pins. J1's shell is used for the shield common which has to be connected to TP1. Therefore J1's outside shell will need to be isolated from the ground.

J2-J4 are Flat Coil Probe inputs. Each connector has provision for three flat coil pairs and a probe identification. The connectors are round Hypertronics 12 pin female contact cable to wire solder connectors. To connect to the FIB, hard wire connections are made from J2-J4 to the FIB pad array labeled J2-J4. A small multiconductor cable of 26 gauge is suggested for this.

J5 and JB5 are used to interface wiring for probe identification. J5 is a female 15 pin 'D' connector and is mounted on top of the ICB, and JB5 is a male 15 pin 'D' connector and is mounted on the bottom. The wiring between the connectors is one to one. The same wires are routed to J10.

J6, JB6, J7, JB7 are encoder input connectors. J6 and J7 are 6 pin male MS style connectors with Jam-Nut mounting and printed circuit compatible pins. JB6 and JB7 are wiring points for the cables that plug into the SIM modules. The wiring is one to one between pairs J6 - JB6 and J7 - JB7.

J8 and J9 are used to provide test signals from the PIM to the SIM. These signals are generated in the PIM module. To use these test signals, a jumper cable will need to be connected from J8 or J9 to J7 or J6. J8 and J9 are 6 pin female MS style connectors with Jam-Nut mounting and printed circuit compatible pins.

JB8 and JB9. These interface connectors are needed because test stand input connectors differ from CCM's input connectors JB8 connects input signals to CCM1 and JB9 to CCM2. Both connectors are wired in parallel to J10 and J11 accordingly. By inserting the ICB into either of these connectors, the system may be configured for test or measurement modes as shown in Figures 3 and 4. JB8 and JB9 are AMP Inc. 40 pin, female, 'D', straight , Amplite series type connectors .

J10 is the connector used in conjunction with the ICB to configure coil inputs to the CCMs. A number of pins are reserved for identification signals which are jumpered to J5 and JB5 via wiring on the ICB. J10 is a 126 pin, female, Hypertronics connector.

J11 is the connector used with the ICB to connect test signals from the PIM to CCMs. It mirrors that of J10 in a way that test signals from the PIM module are wired on the same pins as the coil inputs on J10. The input signal wiring to the CCM's are in parallel with the wiring on J10. Therefore the same ICB can be used on J10 and J11.

JB1 serves as the interface to the PIM which provides analog test signals for CCMs and SIM. JB1 is a 60 pin, female, 'D', straight, Amplite series type connector from AMP, Inc. It mounts on the bottom of the printed circuit board.

4. System Configurations

The Fanout Interface allows the user to configure the PAFMS for either measurement or test mode by reconnecting CCM's and SIM's input signals from the Magnet Test Stand input connectors to test connectors residing on the FIB. Cable configurations for both modes are shown in Figures 3 and 4.
