Note: this article addresses options for sharing interfacing between Cirris’ Signature series, Easy-Wire™ CR and CH2 harness testers. For information on interfacing options on our Signature line of stand-alone testers, click here.

Several benefits may be had by standardizing to one connector for your cable testing interfaces. These benefits include:

  • Using the same fixturing on a CR for low voltage guided build followed by high voltage tests with a CH2 test system.
  • Reducing the variety of adapting cables needed for your cables and/or harnesses.
  • Reducing overall cost by standardizing to one type of connector.
  • Sharing the same fixturing across all Cirris tester platforms.

You may already have adapting cables and fixturing and want to adapt your cable tester to a connector that is not standard for connections to the device under test (DUT).  Cirris provides full flexibility and conversion with the following:

CH2 Custom Connector Interfaces

An example of a custom connector interface to the CH2 is the Cirris adapter panel that is designed to mate to any connector you may presently use.

If you are still making the choice or already have a choice in place and need to manage some limitations, see the following:

Cost of interfacing

A1KM-64 Adapters are an inexpensive option for connecting CH2 (Eurodin) Style Connections to an 1100 series, EasyTouch, and Touch 1 Units.

Ribbon Cable comes in at perhaps the lower cost and is a good option for CR Interfacing.

A non-standard connector already in use might even be less expensive.

Mating Life Cycles

A connector saver can be used with the connector and is inexpensively replaced when connectors need repair.

CH2 Connector Saver Part Number ADCS-C2.

The male pins of the 64-pin header have a very long life on a tester like the CR. While the female pins on the ribbon cables are easy and cost-effective to replace when repair is necessary.

Custom Connectors such as DL connectors can have a potential for very long life.

Adapters desired for each DUT connector. Small number of contacts in DUT connector.

Can only have half the number of contacts compared to a 64-pin header.  

Possibility of fewer contacts per connector.

Performance

These style connectors have an excellent overall performance.

#28 AWG wire in IDC connectors will add to fixturing resistance. PVC insulation is substandard for high IR performance at voltages above 1000VDC.

Use discrete 64-pin header when HV or Insulation Resistance requirements are demanding.

Custom connectors will need further evaluation on performance when choosing the style of connector.

Speed of connect/disconnect

The screw attachment of a VME (Eurodin) style connectors will take more time to change over. Use connector savers that have ejector handles on the CH2 when needed.
