Motherboard Specific Notes
RS-232
An on-board COM header is not available on many modern motherboards including the Tyan Thunder
S2676. Therefore it is necessary to use the Merging USB – RS232 converter and reworked Y-type USB
cables.
Tyan Thunder S2676 motherboard only
(VCube HD2K only)
On this motherboard, there are only 2 on-board USB headers. This means you can only connect the USB –
RS232 converter and ONE front panel USB port. The left one is connected and the right is obscured by an
“
NC
” sticker.
Note:
One port is connected to the USB to RS-232 module and the remaining one to the
front panel USB/1394 module.
A reworked Y-cable is used to connect the USB to RS-232 converter module and a normal
Y-type cable for the front panel module. The spare connector is retained in case the
motherboard is later upgraded to a model with more than two USB headers.
