Notes for Virtual Switches, Page Three

1. The Expansion port on the rear of the Alpha-Link can be used to perform firmware upgrades. The Alpha-Link LIVE

unit runs different firmware to the other units in the Alpha-Link range but the Expansion port is unable to detect

this difference. Therefore, to guard against accidental and incorrect firmware updates, the Alpha-Link LIVE will by

default not accept firmware updates over the Expansion port. At the time of writing, firmware update is not

possible over the MADI port.

2. When EXT is selected as the clock source and ‘MADI or Video’ has been selected in virtual switches page two,

setting switches 5 through 8 to ‘off’ will enable the clock signal embedded in the incoming MADI stream to be

used as the clock source.

3. When EXT is selected as the clock source and ‘MADI or Video’ has been selected in virtual switches page two,

these virtual switches allow Alpha-Link to lock to an applied NTSC/colour (29.97Hz) video sync signal. Because

the video sync signal obviously carries no sample rate information, it will be necessary to select the required

sample rate using the appropriate switches.

4. When EXT is selected as the clock source and ‘MADI or Video’ has been selected in virtual switches page two,

these virtual switches allow Alpha-Link to lock to an applied PAL video sync signal. Because the video sync signal

obviously carries no sample rate information, it will be necessary to select the required sample rate using the

appropriate switches.
