10. CAMAC Interface Wiring Tables

10.1. JackRec Table

This table contains the jack number and jack types for every connector in the interfaces. It is used to validate connector number entries in the RPrecord, Zrecord, and Trecord tables and to specify connector type on some of the reports.

The two fields, JackTypA and JackTypB, allow specification of both halves of the connector set.

JackNo

Name of the connector.

JackTypA

Connector type.

JackTypB

Connector type.

Comments

Comments field.

10.2. RPrecord Table

This table specifies a connection for one pair in a device connector on the interface.

RPdskey_Label, RPdskey_DRefNme

Parameter associated with this pair.

RPpair

Pair number of the parameter.

RPjack

Jack this connection is located in.

PinA

First pin in the pair.

PinB

Second pin in the pair.

ColorA

Color of the first wire in the pair.

Validated by ColKeys.ColNme.

ColorB

Color of the second wire in the pair.

Validated by ColKeys.ColNme.

SigNameA

Name of the signal associated with the first wire in the pair.

SigNameB

Name of the signal associated with the second wire in the pair.

Buss

Bus to connect to in order to obtain power. If no connection is required, use "none" in this field.

Validated by BusKeys.BusNme.

BussP1

First bus pin.

BussP2

Second bus pin.

Comments1

Comments field.

Comments2

Comments field.

10.3. Zrecord Table

This table is used to define a connection point to a CAMAC module. Connection points to modules are associated with DataRecs.

ZrecId

RecId of the DataRec this record is associated with.

Zpair

Wire pair number for the RecId.

PinA

First pin in the pair.

PinB

Second pin in the pair.

Zjack

Jack this connection is located in.

Comments1

Comments field.

Comments2

Comments field.

10.4. Trecord Table

This table is used to provide connection pairs between any two jacks in the interface without the use of data points.

Typically this is used where connections need to be made between two points in an interface, but there is no entry in the database that corresponds to the signal.

For example:

  1. If there are two interfaces associated with a single CAMAC crate, signals often need to be routed from one interface to the other through the trunk cable. In this case it is used to pass signals on the destination side of the jumper's connection to the device connector.

  2. It is used to make the shield connections for the device cables. In this case the destination connector is a ground block inside the interface and there is only one wire in the pair.

  3. In cases where signals must be passed from connector to another without involving CAMAC. This can happen when hardware interlocks need to be passed between devices.

The fields in the Trecord table are:

TRindex

Index number used to identify the record.

JackA

"Source" jack.

Validated by JackRec.JackNo.

JackB

"Destination" jack.

Validated by JackRec.JackNo.

PinA1

First "source" pin.

PinA2

Second "source" pin.

PinB1

First "destination" pin.

PinB2

Second "destination" pin.

ColorA

First wire color pin.

Validated by ColKeys.ColNme.

ColorB

Second wire color pin.

Validated by ColKeys.ColNme.

SigNameA

First signal name.

SigNameB

Second signal name.

Comments1

"Source" connection first comment field.

Comments2

"Source" connection second comment field.

Comments3

"Destination" connection first comment field.

Comments4

"Destination" connection second comment field.
