Abstract
An apparatus that allows for access to any and all registers of a central processing unit in a line replaceable unit (LRU) without a need to open the housing of the LRU is provided. The apparatus may receive write or read packets from an external device and relay the same to an LRU. The apparatus may receive state information from one or more registers of the LRU in response. The apparatus may transmit or transfer the state information to an external device. The apparatus may be used to update firmware in the LRU, for diagnostics or testing.
Claims18
An apparatus comprising:
- a small-form factor connector configured to receive a fiber optic cable, the apparatus being connectable to a unit under testing (UUT) via the fiber optic cable;
- a control area network (CAN) interface or a universal serial bus (USB) interface, the apparatus being connectable to an external device via at least one of the CAN interface or USB interface;
- and
- a processor configured to:
- receive a plurality of register addresses for registers in a central processing unit in the UUT from the external device via at least one of the CAN interface or USB interface to set up a reading of the corresponding registers in the central processing unit;
- relay the plurality of register addresses to the central processing unit via the fiber optic cable;
- and
- receive state information corresponding to each of the plurality of register addresses periodically, wherein the period is less than or equal to an analog to digital conversion of an analog to digital converter (ADC) in the UUT.

An apparatus comprising:
- a small-form factor connector configured to receive a fiber optic cable, the apparatus being connectable to a unit under testing (UUT) via the fiber optic cable;
- an input analog interface, the input analog interface is configured to connect with an external device;
- an analog to digital converter (ADC);
- and
- a processor connected to the ADC, wherein the apparatus is configured to receive at least one target analog signal from the external device via the input analog interface and convert the at least one target analog signal into at least one target digital signal, respectively, and
- the processor is configured to transmit the target digital signal to a central processing unit in the UUT via the fiber optic cable, wherein the at least one target analog signal is associated with one or more register addresses in the central processing unit, wherein the processor is configured to periodically receive state information from the one or more register addresses, where the period is less than or equal to an analog to digital conversion of an analog to digital converter (ADC) in the UUT.

A diagnostic kit comprising:
- a fiber optic cable;
- and
- a mobile device comprising a housing having a small-form factor connector configured to receive the fiber optic cable, the fiber optic cable connectable to a port in a housing of a unit under testing (UUT), the housing further having a control area network (CAN) interface or a universal serial bus (USB) interface, the mobile device being connectable to an external device via at least one of the CAN interface or USB interface;
- the mobile device further comprising:
- a processor configured to:
- receive a plurality of register addresses for registers in a central processing unit in the UUT from the external device via at least one of the CAN interface or USB interface to set up a reading of the corresponding registers in the UUT;
- relay the plurality of register addresses to the central processing unit via the fiber optic cable;
- and
- receive state information corresponding to each of the plurality of register address periodically, wherein the period is less than or equal to an analog to digital conversion of an analog to digital converter (ADC) in the UUT.
