DESCRIPTION
The USB-1553 module is a small, portable, USB device that provides new levels of performance and flexibility for systems interfacing to a MIL-STD-1553 data bus. There are up to two dual redundant MIL-STD-1553 channels operating in BC, RT, MT, and RT/MT modes. The unit can be powered directly from the USB interface or by an external power source (optional). The device includes the MIL-STD-1553 C API (Application Programming Interface) library and drivers, along with source code samples, and detailed documentation. |

APPLICATION
This module is the perfect COTS solution for MIL-STD-1553 data bus systems. Its small size, lightweight, and durable construction makes it an ideal choice for use in avionics labs, field service, flight line test equipment, and flight instrumentation applications. The USB interface makes it suitable for use with desktop, laptop, or tablet computers. |

|
DISCRETE I/O
The device includes 16 (digital 5V) discrete that are individually programmable as inputs or outputs (Open/Ground Discrete). The discrete outputs can be used for a variety of purposes, including triggering events, indicating status, and general-purpose use. |
|
| |
POWER
The module has been designed to source power from USB port. In cases where USB port current is not sufficient, a low-cost 5V AC adaptor may be used to power the device. The unit requires that a minimum of 500 mA of current is available from USB port from the moment the USB connection is made. When the unit is running exclusively from USB power a connection to a high-powered USB hub port is required. The high-powered USB hub port must have an input voltage range of 4.75V to 5.25V.
The unit contains a DC power jack for connection to an external 5V power source. Once connected, the USB device will stop drawing power from the USB port. The allowable range for this DC input is 5V±5% (4.75V to 5.25V). The DC jack is designed to interface with off-the-shelf AC adaptors.

SOFTWARE
This USB Avionics Device includes a Bus Monitor and Analysis Software. Source code provided for samples, and detailed documentation. The device comes with a powerful set of library functions to access the entire MIL-STD-1553B functionality. The drivers are designed in a modular fashion consisting of component functions and application functions. The user’s test program can be developed with few calls to the driver by using the set of application functions provided. Driver and high-level API libraries for DOS, Windows 2000/XP are available. Sample programs for BC, RT, MT modes are included.
MIL-STD-1553 CHANNELS
Each 1553 channel can emulate as a Bus Controller (BC), a Remote Terminal (RT), or a Bus Monitor (MT). Standard features include 64KB of RAM per 1553 channel, transformer and direct coupling, triggers, extensive BC & RT frame structures, RT Status Bit and Mode Code responses, along with advanced BC functionality. The advanced BC architecture provides a high degree of flexibility and autonomy by providing message schedule control, minimizing host overhead for asynchronous message insertion, facilitating bulk data transfers, double buffering, message retry, bus switching strategies, data logging, and fault reporting.
The RT architecture provides flexibility in meeting all common MIL-STD-1553B protocols. The choices of RT buffering and interrupt options provide robust support for synchronous and asynchronous messaging, while ensuring data sample consistency and supporting bulk data transfers.
The interface includes a message monitor mode and a combined RT/MT mode where the MT will monitor all 1553 communications on the bus including the 1553 Channel's assigned RT addresses.
The Bus Monitor Mode provides for Selective Message Monitoring and Combined RT/Message Monitor Mode. Besides providing monitor filtering based on RT address, T/R bit, and sub address, the message monitor eliminates the need to determine the start and end of messages by software. A combined RT/MT mode allows the device to run in both modes of operation at the same time on the bus. |
