Digital I/O Capabilities
Digital I/O capability is often requested by Cirris customers looking to automate their testing processes. Cirris Systems has offered digital I/O capabilities on our older 1000R+ and 1000H+ testers for many years. Now, Cirris offers easier, more comprehensive Digital I/O capability in the Touch 1 and 1100R+/H+ series testers. The different models are listed below with associated information to help you decide which model will work best for your digital I/O application.
Touch 1, 1100R+ and 1100H+
|
(3.9 Mb, Audio and Video, 117 Sec. play time, requires Flash plug-in).
Digital I/O on your Touch 1, 1100R+, or 1100H+ tester makes it easy to customize your test process.
Use digital inputs to:
- Remotely "Start Test" with an external switch, start button, input from a PLC, etc.
- Use Palm buttons, light curtains etc. as a hipot safety switch
Use digital outputs to trigger items such as:
- Status lights
- Device locks
- Stampers and Markers
- Audio Output

easy-wire CR
Getting Started Controlling Inputs/Outputs with Cirris easy-wire Software
To enable your easy-wire CR tester for use of the digital I/O capability follow these three steps.
- Step 1. Purchase the Upgraded easy-wire software which includes the Virtual I/O Package. (Part # SIO-EW)
- Step 2. Purchase (Direct Logic DL05 Micro PLC) hardware from Direct Logic
(Click Here for link to Direct Logic web page)
- Step 3. Visit the easy-wire Help System. (see screen shot from easy-wire help system)The help system will provide an overview of the External I/O system and give examples to help get you up and running quickly. Just click on HELP and search for I/O.

1000R+ and 1000H+ Testers
| The Digital I/O connector on the Signature 1000R+/H+ is found on the serial interface board, which is inside the chassis. You will need to remove the microprocessor assembly from the chassis to access this connector. This connector gives you access to the collector and emitter terminals of the transistors that are shown in the diagrams below. Click on the photo to the right to see an alternate photo of the inside of the 1000R+ with the connector points highlighted.

Digital I/O can be used to signal automated manufacturing equipment for many diverse purposes. For example a "bad cable" signal might actuate a machine to cut the connector off the cable. Thus insuring that any cable that tests "bad" is destroyed and not mistakenly shipped to a customer. A "Good Cable" signal may activate a robot to move the cable to the next processing point etc., etc.
|
 |
In like manner, Digital I/O can also be used to signal automated manufacturing equipment that the testing process on a cable is completed. The "test completed" signal may sound a buzzer, activate a process or initiate some other action.
As the schematics indicate the output signal from the tester can be configured so that the output to the PCL can be active high or active low.

This drawing illustrates the configuration necessary to activate a relay when the cable test "good" or activate a different relay when the cable tests "bad".
