24 Channels. Digital. Signal Output & Monitoring. Record and output digital signals. The USB-PIO-OEM features three 8-bit bidirectional ports. The port lines are led through to the module pins. OEM. Simply Integrate. The module is an OEM version of the USB-PIO of bmcm to equip your device with a modern and powerful USB interface. Special emphasis was put on the easy implementation of both hardware and software components. Plug & Play. The connection to the PC is realized via USB. The USB-PIO-OEM provides all typical USB features (e.g. Plug&Play, Hot-Plug). Up to 127 devices can be connected and installed during operation. Powered by USB. The device is supplied with power via the USB interface. This reduces cabling efforts to a minimum and makes mobile measurements a lot easier. Extra Small. Extra Low-Priced. In size and construction type, the USB-PIO-OEM module looks like a 40-pin DIL IC and can easily be integrated in other devices. Not only the size is extra small but also the price. Open for Everyone. Widely supported: The USB-PIO-OEM can be used under Windows® XP/7/8/10 as well as under MAC OS X, Free BSD, and Linux. The OEM module is 100% software compatible to the USB-PIO. The complete software for installation and programming of the device is included for free. NextView®4. Try for Free. The module is supported by NextView® 4, the software for data acquisition and analysis. A fully functional 30-day trial is included with delivery to directly test the functionality of the USB-PIO-OEM. Accessory. Just Makes it Easier. For testing purposes or to make your own developments easier, the test tool USB-PIO-OEM-TL is available. It provides standard connectors for the digital lines and the USB bus. In addition, 24 LEDs allow immediate status control of the individual I/O pins. ► www.bmcm.de bavarian measurement company munich

1 Board View and Pin Assignment PIN 20 The USB-PIO-OEM features a ^-controller providing 24 digital channels with TTL/CMOS level (low: 0V..1V; high: 3.0V..5V) designed as three 8-bit digital ports A, B, C. The lines are bidirectional. The direction is set to input or output in groups of 8 (port C: 4) via software. The connections to the digital interfaces are accessible at the pins of the USB-PIO-OEM. The pin assignment of the USB-PIO-OEM is listed in the following table. O • Do not apply voltage to the ports without the relevant protective circuit. Two outputs connected with each other may...

2 Interfacing Examples USB-B Socket USB-PIO-OEM Mocue 2.1 Connect Input Signal Exemplarily, the connection of an input signal at pin 3 and 10 of the USB-PIO-OEM is illustrated. The 1kQ resistor and the 100pF capacitor have protective and noise suppressive functions. For voltages higher than 5V a voltage divider is required (see calculation below chapter 2.3). 2.2 Connect LED, Relay to Digital Output In the figure displayed above, pin 27 and 38 are set to output. At pin 27, the connection of an LED is shown. At pin 38, a relay is controlled via a transistor. Please also observe the total...

3 Software Installation All software and documentation available for the USB-PIO-OEM (installed as "USB-PIO") are integrated on the "Software Collection" CD included with delivery. When inserting the CD, a CD starter opens automatically (otherwise: start openhtml.exe). Change to the product page of the USB-PIO by selecting the entry "Products" in the CD starter and then the hardware ("USB-PIO") listed under the interface "USB". For detailed information about installing or operating the software, please see the corresponding manuals. The Adobe Acrobat Reader is required to open the...

Plug&Play Installation As soon as the USB-PIO-OEM is connected to the PC, the new hardware will be announced. Since the driver package has been copied to hard disc before, the hardware will be installed automatically under Windows® 7/8/10. Under Windows® XP, the automatic hardware detection is started by selecting the following: - Windows® 7/8/10: no specifications required - Windows® XP: "Install the software automatically" (SP2: do not connect with Windows® Update!) Check Installation The entry "Data Acquisition (BMC Messsysteme GmbH)" is included in the Windows® Device Manager after...

4 Test Tool USB-PIO-OEM-TL The test adapter USB-PIO-OEM-TL is provided to directly test the functions of the USB-PIO-OEM. Plug the OEM module onto the 40-pin socket. O Make sure the orientation of the module is correct (see Figure 1, pin 1 top right) to avoid damages of the module. 4.1 Digital Inputs and Outputs The 24 digital lines are led through to the 25-pin D-Sub female connector (P1, see Figure 1) of the test tool. The pin assignment of the USB-PIO-OEM as well as of the D-Sub25 female of the USB-PIO-OEM-TL are listed in the following table. PortC PortB Port A O DGND = digital ground

• Do not apply voltage to the ports without the relevant protective circuit. Two outputs connected with each other may get damaged by the high flow of current. • The digital inputs are equipped with an internal 100kQ pull-down resistor for open inputs to be constantly low. Via the USB connector type B (P2, see Figure 1, the test tool and the OEM module are connected to the USB interface of the PC and also supplied by it (Vusb = 4..5V, pins 2-3 ("USB PWR") of the 3-pin jumper J1 closed).

5 Important Notes for Using the USB-PIO-OEM • The device is only suitable for extra-low voltages - please observe the relevant regulations! Only use the device with housing closed. ESD voltages at open lines may cause malfunction. • Definition and test of the CE-standards to be applied must be made by the operator! • Only use non-solvent detergents for cleaning. The product is designed to be maintenance-free. • Signal cables are connected at the module pins - preferably use shielded cables. For best possible interference suppression, connect shield at one end only. Close open inputs if...
