Mode after the data has been sampled. It is switched to
whatever other mode best suits the application.

The second reason you may need the Recorder

Mode menu is that this is where you will find the com-
mand to reformat a SmartMedia Flash Card. If the for-
mat of a SmartMedia Flash Card is damaged, or if the
Flash Card is reformatted in a PC, it will need to be refor-
matted. If you reformat a SmartMedia Flash Card on a
PC, it will work OK on a PC, but not in the BR-SmartMedia
until it has been reformatted. We have found that this will
even repair SmartMedia Flash Cards that have stopped
working in MP3 players and other devices that expect
the format to be in the SmartMedia Forum’s standard ar-
rangement. PCs do not format Flash Cards to this stan-
dard.

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 chan-

nels of data, the DMX-512 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 BR-SmartMedia 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 dis-
played as a flickering pattern.

All 256 channels of data are also transmitted through the Z-

Brick port. Depending on the mode and data stored, 256 or 512
