Persistence of Scaling Mode

The Scaling Mode has two levels of persistence – the basic level happens automatically and can be considered

temporary; the advanced level is the result of sending the PERSISTAV command to the DXLink Fiber Output Board and

is permanent (unless the Scaling Mode is changed and the PERSISTAV command is sent again).

Basic Persistence

DXLink Fiber RX – automatically persists the current Scaling Mode locally. The current state of the scaler is always

stored in non-volatile memory on the DXLink Fiber RX.

The current state of the scaler on the DXLink Fiber RX can be changed using one of the following methods:

By sending the VIDOUT_SCALE SEND_COMMAND (page 68).

By pressing the Scaling button.

In either case – changes to the Scaling Mode on the RX are also sent to the DXLink Output Board and stored in volatile

memory.

DXLink Fiber Board – automatically receives the Scaling Mode from an attached RX and stores it in volatile memory.

The DXLink Output Board pushes the current Scaling Mode down to the DXLink Fiber RX if any of the following

occurs: (1) the RX is power cycled independent of the switcher; (2) the RX is disconnected from the DXLink Output

Board and then reconnected; or (3) a different DXLink Fiber RX is connected to the DXLink Output board. The DXLink

Output Board’s current Scaling Mode then takes precedence and becomes the current Scaling Mode on the DXLink

Fiber RX.

Advanced Persistence

A Scaling Mode can be “permanently” persisted to the DXLink Fiber Output Board (in its non-volatile memory) using

one of the following methods:

Using the PERSISTAV SEND_COMMAND (for details, see page 84).

Using DGX Configuration Software to set and persist the Scaling Mode for the connector on the DXLink

Fiber Output Board on the Enova DGX Switcher.

In either case – when the switcher is power cycled, the DXLink Fiber Output Board sends the advanced data for the

Scaling Mode (from non-volatile memory) to the DXLink Fiber RX. This will override any locally persisted Scaling

Mode on the RX and become the new currently persisted (local) Scaling Mode.
