17. Performance and Technical Specifications
Compatibility
External device information
The IntelliBridge VueLink Open Interface (IVOI) Protocol is unidirectional, i.e. a monitor that adheres to
the protocol can display data received from the Tetra Graph but cannot remotely control the device.
Note that the user controls the monitoring using the TetraGraph Monitor graphical user interface when
interfacing with the Philips monitor.
The device transfers 9 measurement numerics and two waves to the monitor, using the Open Interface
protocol. The device makes use of the INOP (inoperable) functionality in the Open Interface protocol, to
alert the user about a loose connector, low battery or if somebody has pressed pause on the device.
Supported Devices
This integration supports the TetraGraph only and the minimum version that is supported is 34b.22b.12a.
Supported hosts
Senzime’s implementation of the IVOI protocol was carried out using Philips SpecTool (1040), the
IntelliBridge and VueLink Open Interface - Specification Tool (Version B). All hosts that support this
version of the IVOI protocol operating at 19200 Baud and open interface driver A.6 and higher will be
compatible.
