Introduction
The Tx Link connection module provides connectivity between EasyCare Tx
software and a positive airway pressure therapy device (therapy device).
Furthermore, it relays real-time signals measured by the therapy device to a
polysomnograph (PSG).
The Tx Link is also a component of the VPAP Tx Lab System. The VPAP Tx Lab
System provides remote PC control of a therapy device capable of delivering
multiple therapy modes. The system comprises:
1. VPAP Tx or other compatible ResMed therapy device1.
2. Tx Link connection module.
3. EasyCare Tx titration software2.
This guide provides instructions for the Tx Link. Refer to the VPAP Tx Clinical
Guide and EasyCare Tx Online Help for instructions on their use.
CAUTION
In the US, Federal law restricts this device to sale by or on the order of a
physician.

Intended use
The Tx Link is intended to provide connectivity between ResMed EasyCare Tx
software and ResMed compatible therapy devices. The Tx Link relays real-time
signals measured by the ResMed compatible therapy device to a
polysomnograph (PSG).
The Tx Link is intended to be used in a clinical environment.

Components
The following items are supplied with the Tx Link:
• 5V DC power pack and plug blade attachments
• serial cable to connect the Tx Link to a compatible ResMed therapy device
• ethernet patch cable.
Optional components include:
• EasyCare Tx CD
• USB cable to connect the Tx Link to a compatible ResMed therapy device.

1Only attach a ResMed therapy device compliant with IEC 60601-1.
2EasyCare Tx should be installed on a PC compliant with IEC 60950.

Device connections 3
Device connections

PSG connections
Tx Link provides up to six color-coded analog DC outputs (A-F), which can be
used to connect the real-time streams measured by the ResMed therapy device
to a PSG system. To support many different types of PSG systems, each DC
output is available at three connection points. Each mono jack connector
provides one channel only. Each modular connector provides two channels.
