ETHUSB Ethernet not communicating on Mac OS X 10.7 or above

The following is a brief overview of the steps to verify that the USBETH is installed correctly—for more detailed instructions, click to open App Note 280 – ETHUSB Not Communicating on Mac.

NOTE: The following information applies to older systems. The current version ETHUSB is a different model.

1. Download and install at least version 4.0.0 of the driver for the adapter from this website. The driver should be appropriate for the Mac operating system being used.

2. After computer reboots, verify that the adapter is recognized.

3. Go to Software > Extensions and search for AX88772 in the list and verify that version 4.0.0 is installed:

4. Configure the network. Open System Preferences > Network. Select “USB Ethernet” to adjust the adapter settings. Set them to the following manual settings:

5. Optional: Adjust the network ordering such that USB Ethernet is first on the list.

a)       Go to the “gear” at the bottom of the list and choose “Set Service Order” from the list.

b)      In the dialog, drag “USB Ethernet” above Ethernet in the list.

c)       Click OK and close System Preferences to apply the network settings.

6. Turn on the MP150 (or power cycle it if it was on).

7. Check the amber light on the ETHUSB.

8. Launch AcqKnowledge.

For Mac OS X 10.8 or above

a)       (2.5) Now the USB network interface must be added (10.9+). Open System Preferences > Network. Click on the “+” in the lower left to “Create a new service.

b)      In the next dialog that appears, select the “USB Ethernet” interface and give it a default service name. “USB Ethernet” will now be available in the list in the main dialog.

c)       (3.5) Unlike previous operating systems, when the cable is connected it will show up as functional with an MP150 when it has a yellow dot.

Cardiac Output amplifier

NICO Smart Amplifier

The NICO Smart Amplifier is specifically designed to measure thoracic impedance for performing noninvasive cardiac output measurements. The amplifier terminates in two connectors for impedance (Z) and its derivative (dZ), and has a 3 m cable that connects directly to an AMI100D Amplifier Input Module. Use with EL526 strip electrodes and CBL246 adapter or with EL500 […]
