card. Through the interface card, UNO-4683 can also adopt the standard
PCI card, PCIe-mini card, mini-PCI card as well as the PCI-104 card.
Due to the UNO-4683 is an embedded system, the power providing for

C condition) for all slots.
Before you configure all the module and plug-in card, please note not to
exceed the power limit.
All the expanding IO modules are design for embedded application, the
power efficiency and thermal are well controlled. But if 3rd plug-in card
is required to work in the UNO-4683, please check the related power con-
sumption and working condition carefully. In the normal condition, the
o
ambiance temperature inside the chassis would be 15
C higher than the
environment temperature of UNO-4683. To avoid the abnormal high
internal temperature damage the plug-in card, UNO-4683 provide the
system temperature alarm function, please refer to chapter 2.9 for detail.
UNO-4683 also support the optional fan for user to resolve the thermal
issue of the 3rd party plug-in card which is with high power consumption
or bad power efficiency. It is not recommended to use this kind of card in
