About the Model 494.16 VD/DUC Mezzanine Card
The Model 494.16 VD/DUC mezzanine card includes a valve driver and a digital universal conditioner resource
on the same card. You can configure the resources in this card in different combinations with the Hwi File
Editor. These combinations are reflected in the associated resource labels in the Station Builder and the
Station Manager applications.
You can use the Hwi File Editor to configure the resources in one of two combinations:
• Use all of the resources to create a three-stage valve driver (the DUC is used to condition the LVDT of
the third stage of the servovalve),
• Split the resources into a two-stage valve driver and an independent DUC.
For example, suppose you use the Hwi File Editor to configure this type of mezzanine card type as a “DUC
and 2SVD,” with the DUC output available at S4-J1A and the two-stage valve driver output available at S4-J1B.
In this case, the resources appear as follows in the Station Builder application:
• The two-stage valve driver appears in the Hardware Output Resources list as “494.16 2SVD S4-J1B”.
• The independent DUC appears in the Hardware Input Resources list as “494.16 DUC S4-J1A”.
Likewise, the resources appear in as follows in the Station Manager application:
• The two-stage valve driver appears in the Channel Drive window as “494.16 2 Stage Valve Driver”.
• The independent DUC appears in the Channel Inputs Signal window as “494.16 DC Conditioner”.
How to Allocate Resources
1. In the Hardware tab of the Output Resources list, select the hardware resource you want to allocate and
then click +.
Note:
The Station tab of the Output Resources list pertains only to systems that use Transformations
(DOF systems).
2. In the Display name box, change the resource name as desired.
Note:
It is good practice to keep your channel resource names short, because long names may not be
visible in all windows.
3. In the Internal name box, type or select an internal name for the channel resource.
