2. PRODUCT OVERVIEW 2.1 Overview Systran’s BusXchange, shown in Figure 2-1, is a MIL-STD-1553 “virtual patch panel” housed in a 19” rack-mountable chassis. This 16 x 16 crosspoint switch provides differential connections from 16 transformer-coupled Line Replaceable Unit (LRU) inputs to 16 MIL-STD-1553 differential buses. The BusXchange eliminates time- consuming bus rewiring between different avionics simulations or test scenarios.
PRODUCT OVERVIEW 2.2 BusXchange Features The BusXchange has the following features: • Up to 16 transformer-coupled LRU inputs via standard concentric twinax connectors. This product is NOT designed to support direct-coupled LRU devices. • Up to 16 MIL-STD-1553 bus output connections via standard concentric twinax connector.
PRODUCT OVERVIEW 2.3 Structure The BusXchange has three primary functions: 1. Connect LRU inputs to the appropriate specified Bus outputs. 2. Provide an out-of-band command line interface to the user. 3. Provide status information to the user via the command line interface and front- panel LCD status display.
PRODUCT OVERVIEW 2.4 Connecting a Terminal A VT-100 compliant terminal (or terminal program running on a PC) can be connected to the BusXchange using an RS-232 cable. Data rates of 9600, 19200, 38400, and 57600 baud are supported. The terminal should be set for 8 data bits, 1 stop bit, and no parity. It is not necessary to set the baud rate.
PRODUCT OVERVIEW 2.8 Applications The BusXchange is a “virtual patch-panel” which eliminates time-consuming bus rewiring between different MIL-STD-1553 simulations or test scenarios. NOTE : The BusXchange is designed as a static bus configuration tool. This eliminates time-consuming bus rewiring between different avionics configurations. The BusXchange is NOT designed to switch LRUs while a device is actively transmitting.

INSTALLATION 2. For each of the LRU connections, a coupling transformer is used. J35 through J50 are the associated headers for LRUs 0 though F, respectively. In the default shipping position, the center-tap of this transformer is not connected. If the jumpers are moved from the left position to the right position (when viewed from the front of the BusXchange enclosure), the center-tap of the associated coupling transformers will be connected to the analog ground of the BusXchange.
3.7 Connect Power to the BusXchange Power must be connected to the BusXchange. The BusXchange is designed to use a power supply available from Systran: H-AS-PWRSPLY-10 (contact Systran Sales for pricing information). This desktop power supply accepts 120 VAC and provides +5 VDC (+/-5%) at 6 A.
INSTALLATION connectors, contact Methode Electronics, Inc. at (847) 392-3500 or (800) 323-6858, or on the internet at www.methode.com. Rear Panel View Figure 3-4 BusXchange Power Supply Connection NOTE : The diagram is shown looking into the “female” connector on the Multiplex Bus Switch board.
INSTALLATION BusXchange automatically detects the baud rate. Follow the steps below to connect a VT- 100 terminal to the BusXchange: 1. Connect the terminal to the BusXchange using an RS-232 cable. See Appendix B for connector pin definitions. 2. Power on the terminal. 3.

4. COMMAND LINE INTERFACE 4.1 Overview The BusXchange can be configured by using a command line interface. To use the command line interface, a VT-100 compliant terminal must be connected to the BusXchange serial port using an RS-232 cable. The available commands, described below, are composed of ASCII characters and are terminated by a carriage return.
COMMAND LINE INTERFACE Responses: “MBS OK.” No error occurred. Command executed. “MBS ERROR 103: Improperly formatted command.” No extraneous text may follow command. 4.3.2 Control Commands L<LRU#> B<BUS#> Description: This configuration command is used to establish a connection between the specified LRU and Bus. If the LRU has a current connection to a different bus, it will be disconnected from the current bus and connected to the specified bus.
COMMAND LINE INTERFACE Responses: “MBS OK.” No error occurred. Command executed. “MBS ERROR 103: Improperly formatted command.” No extraneous text may follow command. Example: CLR {disconnect all LRUs from their current bus connections} 4.3.3 Status Commands ST L<LRU#> Description: This status command is used to display the current bus connection of the specified LRU.
COMMAND LINE INTERFACE LRU# to Bus# LRU# to Bus# Figure 4-1 ST A Command Response If an LRU is connected to a bus, the number of the bus it is connected to (“0” though “F”) will be displayed in the locations denoted by an “x”. If the LRU is not connected to a bus, the “x”...
