IMPORTANT! Viz 3.2 and later allows up to 255 connections; however, the

number of connections is also limited to the available main memory and texture

memory on the graphics card (see how To limit the number of TCP connections).

• Enable GPI: GPIO device control. Enables frame accurate triggering of commands

via GPI (general purpose interface). We support Sealevel GPI devices for GPI input.

• MUX Isolated Port: Port number for isolated sessions - no data shared (NLE).

• MUX Shared Port: Port number for shared sessions - shared data (NLE).

• MUX Fixed Port: Port number for fixed sessions - shared data, no reference

counting (NLE).

• Still Preview Port: Port number for still preview.

• Multi Touch Port: Port number for listening to multi touch server.

• Multi Touch IP Address: IP address for listening to multi touch server.

• TUIO Port: Sets the TUIO port number for communicating with your TUIO enabled

multi-touch device. TUIO is a protocol for Table-Top Tangible User Interfaces. Default

port for most TUIO applications is 3333.

• Frame Accurate Viz Comm.: Frame accurate commands via TCP (commands

delayed by ring buffer and specified FAVC bias). Enable only for external control that

supports special frame accurate command execution.

• FAVC Bias: Delay fields (in addition to ring buffer size) for frame accurate

commands via TCP or GPI. This is the bias in frames for the commands if Frame

Accurate Viz Command is turned on. Could be negative as well.

• Command Field Dominance: States when to handle the commands sent to the

engine. E.g when set to “Odd retrace counter” all commands will be handled on odd

fields. Not valid in progressive modes. Options are:

• Always

• Odd Retrace Counter: Execute commands at an odd retrace counter.

• Even Retrace Counter: Execute commands at an even retrace counter.

• Intern. Always/Extern. Odd: Execute commands internally always and externally

at an odd retrace counter.

• Intern. Always/Extern. Even: Execute commands internally always and externally

at an even retrace counter.

Shared Memory

• Multicast IP Address: Set the address for synchronizing distributed shared

memory map without Viz Graphic Hub.

• Multicast Port: Synchronize shared memory between all Viz Engines listening to

the multicast.

• UDP Port: Set the UDP listening port for shared memory input.
