Since the FireWire Card is can handle more inputs and outputs than all other I/O Option 
Cards, you will need to understand the following sections to know how to use these expanded 
capabilities. 
 

I.  Setting the Host Mode 

The Fire Wire Card supports 8x8, 16x16, and 24x24 (input x output) operation at 44.1 and 
48 kHz, and 8x8 at 96kHz.  Version 1.0 of the FireWire Card does not support operation 
at 176.4 kHz or 192 kHz sampling rates.  The Host Mode setting, which controls this 
number of I/O channels, is accessed from the Host Mode pull-down menu in the FireWire 
Card I/O Panel (

Windows>IO Configuration>FireWire Card

.)  This menu will 

display only the Host Mode options available for the Sample Rate you are currently using.  
The default Host Mode setting is 8x8. 
 
When the Host Mode is set to 16x16 or 24x24, the inputs from card(s) immediately 
adjacent to the FireWire card (in the same Bucket) are disabled.  For example, selecting 
16x16 Host Mode disables the inputs of card in the second slot of that bucket.  Likewise, 
selecting 24x24 Host Mode disables the inputs of the cards in both the second and third 
slots of that bucket.  This occurs because the Digital X Bus has only 24 input and output 
paths available to each Bucket, so increasing the channel inputs on the FireWire cards 
must be done at the expense of disabling those channel inputs from the adjacent cards. 
 
When you adjust the Host Mode, additional output patch points show up in the FireWire 
Card I/O Panel.  Also, the additional inputs and outputs will be reflected in the various 
input and output assignment menus throughout the console, so your audio source(s) and 
destination(s) are consistent with the other UI elements of the Digital X Bus. 
 

II. Adjusting Sample Clock or Host Mode Settings 

Before changing the FireWire Host Mode or any of the Digital X Bus Clock Settings 
(such as Sample Rate, Sample Clock Source, etc.) you MUST first terminate the 
connection between the FireWire card and your computer.  This is because the FireWire 
Card needs to be reset to accommodate these changes, and resetting the card with an 
active FireWire connection may cause interface lockups or communication problems 
when the card comes out of reset. 
You’ll need to do the following: 

-  Close all Mac or PC applications using the Digital X Bus FireWire driver. 
-  Terminate the FireWire connection (as explained in previous sections) between 

your Mac/PC and the FireWire Card. 

-  Remove the FireWire Cable. 
-  Make any necessary adjustments to the FireWire Host Mode and/or Clock Settings 

on the Digital X Bus. 

-  Remove the FireWire Cable.
