Front Panel

Connector	Description
RX1 TX1	Input and output terminal for the RF signal. RX1 TX1 is an SMA (f) connector with an impedance of 50 Ω and is a single-ended input or output channel.
RX2	Input terminal for the RF signal. RX2 is an SMA (f) connector with an impedance of 50 Ω and is a single-ended input channel.
REF IN	This terminal is not used for this device.
PPS IN	Input terminal for the PPS timing reference. PPS IN is an SMA (f) connector with an impedance of 50 Ω and is a single-ended input channel. PPS IN accepts 0 V to 3.3 V TTL and 0 V to 5 V TTL signals.
MIMO EXPANSION	The MIMO EXPANSION interface port connects two USRP devices using a compatible MIMO cable.
GB ETHERNET	The gigabit Ethernet port accepts an RJ-45 connector and gigabit Ethernet compatible cable (Category 5, Category 5e, or Category 6).
POWER	The power input accepts a 6 V, 3 A external DC power connector.

LED	Indication
A	Indicates the transmit status of the module: OFF-The module is not transmitting data. GREEN-The module is transmitting data.
B	Indicates the status of the physical MIMO cable link: OFF-The modules are not connected using the MIMO cable. GREEN-The modules are connected using the MIMO cable.
C	Indicates the receive status of the module: OFF-The module is not receiving data. GREEN-The module is receiving data.
D	Indicates the firmware status of the module: OFF-The firmware is not loaded. GREEN-The firmware is loaded.
E	Indicates the reference lock status of the LO on the module: OFF-There is no reference signal, or the LO is not locked to a reference signal. BLINKING-The LO is not locked to a reference signal. GREEN-The LO is locked to a reference signal.
F	Indicates the power status of the module: OFF-The module is powered off. GREEN-The module is powered on.
