Condor QPCI-1553 RT Send

Condor QPCI-1553 RT Send block for remote terminal


Simulink® Real-Time™ Library for MIL-STD-1553


A Remote Terminal sends data only if it receives a transmit command from the Bus Controller. This block prepares the board for the next transmit command on this channel, Remote Terminal number, and sub address as specified by the Initialize and RT Initialize blocks.

The data vector signal input to this block is copied to the board message buffer that corresponds to the specified address. The input data vector must have the same length as specified in the Number of words to send parameter. The input vector can be either 16- or 32-bit signed or unsigned data. The block sends only the bottom 16 bits of each element.

Your model might have multiple Remote Terminal Send blocks. To help you locate a particular block, the Remote Terminal Send block displays the channel number and address parameters. The address display has the format:

 remote terminal-T-sub address-number of words

Remote terminal — Is the Remote Terminal parameter

T — Indicates transmit (or send) command

Subaddress — Is the Sub address parameter

Number of words — Is the Number of words to receive parameter

A transmit command for RT 1, sub address 3 to send 2 words has the layout 1-T-3-2.

Block Parameters


From the list of available channels on the board, choose 1, 2, 3, or 4. This channel is initialized for this command stream.

Remote Terminal

From the list, choose a Remote Terminal from 0 to 31. The remote terminal number configured in RT Send and RT Receive must match that specified by the corresponding RT Initialize block.

Sub address

From the list, choose a sub address from 0 to 31. Select the sub address for this message.

Number of words to send

Enter the number of 16-bit integers to send as the data part of this message. This number must be between 1 and 32. The input data vector must have the same vector width.

Sample time

Enter the base sample time or a multiple of the base sample time (-1 means sample time is inherited).

PCI slot (-1:autosearch)

If only one board of this type is in the target computer, enter -1 to locate the board.

If two or more boards of this type are in the target computer, enter the bus number and the PCI slot number of the board associated with this driver block. Use the format [BusNumber,SlotNumber].

To determine the bus number and the PCI slot number, type:

tg = slrt;
getPCIInfo(tg, 'installed')
