PCI Express Mini Card Interface
The BC50R supports the PCI Express Mini Card standard. Its two PCI Express Mini
Card slots are located within the housing.
The PCIe MiniCard sockets on the BC50R support both a USB and a PCIe
interface.
The power supply of the PCIe MiniCard can be reset via GPIO. This power reset is
required when switching from one micro-SIM card to another.
The power of the PCI Express Mini Cards is signaled using two LEDs at the front
panel. They are on when the PCI Express Mini Card is powered and can additionally
be switched off via GPIO.
Micro-SIM Cards
The BC50R provides four micro-SIM Card sockets. Two micro-SIM cards are
attached to one PCIe MiniCard socket. Either micro-SIM card A or micro-SIM card
B can be connected to the PCI Express Mini Card. By default the PCI Express Mini
card is connected to micro-SIM card A.

Binary Inputs and Outputs (DI/DO)
The binary inputs and outputs of the BC50R are optically isolated and accessible via
a 5-pin M12 receptacle. The interfaces are controlled via SMBus. See
