versions 1.1 and later will also bring out the secondary serial port
on the ‘aux.’ serial port from card cage slot #1. This is a six posi-
tion RJ-12 (six position, six conductor modular telephone style
connector) on the card cage. Facing the end of the cable with
the release latch upwards, its pin out is as follows:
COLOR SIGNAL NAME:
LEFT #1 white Signal Ground
#2 black - Serial data out from card
#3 red + Serial data out from card
#4 green - Serial data in to card
#5 yellow + Serial data in to card
RIGHT #6 blue Signal Ground
DMX-512 Data In/Out: Ten pin Male header connector. The BR-
SmartMedia will stop listening to the 'Smart' Brick network whenev-
er there is a DMX-512 signal present on this input.
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 de-
signed for controlling light dimmers, it is now supported by hun-
dreds of suppliers throughout the world for controlling all kinds of
theatrical equipment.
Even though the DMX-512 standard calls for 512 channels of
data, the DMX-512 transmission from PC•MACs is limited to 256
eight bit wide channels. You can address your DMX-512 compati-
ble output devices to respond to any address between 00 and
255. Addresses above the 256th are used in PC•MACs for trans-
mitting 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 displayed as a flick-
ering pattern. Note that at frame rates higher than sixty FPS, not
all 256 channels can be transmitted through the DMX-512 out-
put.
The DMX-512 standard calls out a 5 pin XLR connector or
screw terminals for all connections. All card cages will provide ei-
ther screw terminals or other appropriate connection for attach-
ing the DMX-512 input and output.
