ET_EasyCare_Tx_2_Lab3a.png

After you install the EasyCare Tx 2 software, you can connect the TxLink 2, AirSense 11, AirCurve 11, or AirCurve 11 VPAP Tx, and PSG as shown in the diagram. Please refer to the EasyCare Tx 2 Titration Equipment Installation Guide for more information.

EasyCare Tx 2 relies on standard network protocols to communicate with the TxLink 2 device. Devices are discovered on the local network via Universal Plug and Play (UPnP) and HTTP protocols using ports 1900 and 8080. You create trusted connections to a discovered device from the Add tab in the Administrator window which uses secured web services via port 8443.

  1. Right-click the EasyCare Tx 2 icon on the desktop and select Run as Administrator.

  2. Enter your Windows administrator username and password.

  3. Log in to EasyCare Tx 2 using your Windows username and password. The administrator Dashboard loads.

  4. Click Add.

  5. Use the device name or serial number to identify the TxLink 2 you want to control, and then click the expansion arrow on the right side of the row.

  6. Select Show in Connection Manager to securely connect to this TxLink 2.

  7. Click the Dashboard tab. The TxLink 2 now appears in the trusted devices list for this computer.

  8. Any user (including clinical users) can switch to the Connection Manager tab and click Connect to open a titration window for the added TxLink 2 and its attached therapy device.

    Important

    If no TxLink 2 device is discovered, you won't see any any device details on this screen. You can search for a TxLink 2 device with a known IP address by entering it in the Manually add a device with IP address field.

Note: A Titration Equipment Installation Guide is available on the ResMed website for administrators.

Configure and calibrate

To use a TxLink 2 with a PSG system, you must complete the following three steps to configure and calibrate the DC output signals.

  1. Configure DC output signals

  2. Calibrate DC output signals

  3. Test DC output connectivity

DC output settings are stored for each TxLink 2, so you must repeat the steps described here for every TxLink 2 device. (Learn how to save and load DC output signal configurations.)

For help configuring and calibrating the TxLink 2, contact a ResMed representative or ResMed Technical Care. For help with PSG-related questions, see the PSG manufacturer's documentation.

Configure DC output signals

You must configure and calibrate each TxLink 2 DC output signal connected to the PSG. Each TxLink 2 device supports up to six DC Outputs (labeled A to F). The following table lists the DC output signals you can configure according to your clinical requirements.

You can configure up to six TxLink 2 signals according to your therapeutic requirements (which may vary from patient to patient). You should manually configure the DC outputs for each signal, one at a time, to the output of your choice. Once you configure the DC output signals for a particular bed, you can save this configuration to use on other TxLink 2 devices.

  3. Click either Send high or Send low to send the signal to the PSG via the selected DC output.

  4. Confirm that the PSG software receives and correctly displays the high or low signal.

  5. Click Stop.

  6. Repeat steps 3, 4 and 5 for all DC output channels that require calibration.

After you calibrate the DC output signals, you can test the DC output connectivity for each channel (see Test DC output connectivity).

Test DC output connectivity

It is a good practice to test DC output channels prior to starting each titration. You can confirm the proper operation of the DC output channels visually through the test signal, which appears sequentially across all outputs. Before you test the connectivity, make sure that you have configured DC outputs (see Configure DC output signals) and calibrated DC outputs (see Calibrate DC output signals).

To test DC output signals:

  1. In the titration window, click DC Outputs.

  2. In the DC outputs window, click Test all. EasyCare Tx 2 applies a sequential square wave to each output.
