KB130: How to: Use two PMD-1024 devices on the same computer
Summary
You need more inputs and outputs than a single PMD-1024 device has, so you want to connect two of these devices to the same computer for use with IOLink.
Note: Measurement Computing have changed the name of these devices to USB-1024. If you want to purchase a device, you will find it under USB-1024, not PMD.
