Note that at least one show must be loaded starting at a 'Brick Start' of 0, even if it is only a frame or
two long. PC¥MACs will use this first show to set the frame rate and number of channels stored in the multi-
ple channel Eprom. The BS-DMX-Tx or BS-Serial Smart Brick need this information to index into the Eprom.
If the data sent out from an Eprom BS-DMX-Tx or BS-Serial has shifted compared to what you saw when
you were sending the card DMX data, It is an indication that the ÔstartÕ was set improperly when the Eprom
file set was saved. On a BS-DMX-Tx, the first byte of data in the Eprom is output in DMX-Channel Ф00Х. When
saving the Eprom from PC¥MACs, always set the ÔStart ChannelÕ to Ф00Х. The channels output will then be
exactly what you saw when you were programming.
On the BS-Serial, the offset is a question of the address set for the ÔFirst Address in EpromÕ and the
channel used for the ÔStart ChannelÕ when saving the Eproms from PC¥MACs. The EpromsÕ data can start
at any ÔStart ChannelÕ that you would like. Data from the Eprom will be offset by the ÔFirst Address in EpromÕ
value. These two should be set to the same value if you want the data to appear as it was when you were
programming. DMX-512 devices and Z-Bricks that are addressed below the ÔFirst Address in EpromÕ will re-
ceive Ф00Х values, as will any addresses after the end of the data in the Eprom(s).
