outputs that any Brick card will need. Several different styles of output connectors are avail-
able on the one and two slot card cages. The sixteen slot card cage mounts in seven inch-
es of standard 19Ó rack space (4-1/2 Ò of space behind the panel).
Power requirements for each BS-DMX-Tx or BS-Serial Smart Bricks are 9 to 24 VDC. The BS-
DMX-Tx or BS-Serial Smart Brick itself draws approximately 200 ma..
The DMX-512 standard was developed by the United States Institute for Theatrical
Technology (USITT) for a high speed (250 KBaud) asynchronous serial data link. Although it
was originally designed for controlling light dimmers, it is now supported by hundreds of
suppliers throughout the world for controlling all kinds of theatrical equipment.
Even though the DMX-512 standard calls for up to 512 channels of data, the DMX
transmission from PC¥MACs is limited to 256 eight bit wide channels. You can address your
DMX-512 compatible output devices to respond to any address between 00 and 255.
Addresses above the 256th are used in PC¥MACs for transmitting a checksum. The BS-DMX-
Tx or BS-Serial Smart Bricks can use this to verify that the data received from PC¥MACs has no
transmission errors in it. If you address a light dimmer or other DMX-512 device to addresses
256 or 257, you will see this verification data displayed as a flickering pattern.
