VIA™ to Adapter Bridge Board

The Typical Application diagram in Figure 1 shows the connections required to establish PMBus

 

communication between PMBus-enabled VIA modules and a host PC. The setup for this configuration 
includes directly connecting the VIA Signal Connector cable to the PMBus signal port on the VIA. 
The Adapter Bridge Board, as shown in Figure 2 and Figure 3, provides the necessary connections 
between the VIA Signal Connector Cable and the PMBus to USB Adapter. On Adapter Bridge Board 
USB-ADAPTER-1V-B00, the VIA PMBus address is programmed to 51h by a pre-installed resistor R02. 
On the Adapter Bridge Board USB-ADAPTER-4V-A00, the four VIA PMBus addresses are programmed 
to 51h, 53h, 54h, 55h by pre-installed resistors R02-R05. An LED provides visual indication that VDDB 
(5V) is present. 

Lastly, the PMBus to USB Adapter connects to the user’s computer where the provided Vicor Digital 
Interface Demo GUI is installed.
