Background Story<\/h1>\n

There are two ways to use external I\/O device with TM AOI Edge software. One is installing PCIE I\/O Module on the computer. But if it\u2019s unable to install this module on your computer, you can access I\/O device through a COM Port.<\/p>\n

Here we will use an Advantech RS485 I\/O Module: ADAM-4055 to achieve I\/O control.<\/p>\n

\"\"<\/a><\/p>\n

Introduction of Example<\/h1>\n

We will use an external camera to detect objects, and how to trigger the camera to photo depends on the state of the toggle switch. The pins of the switch is connected to a DI port of ADAM-4055, and signals are read in AOI Edge by using a USB-RS485 cable.<\/p>\n

When the switch turns on which also means the connected DI port triggers, running Vision Job for object detection.<\/p>\n
