Br-ANA Hardware Configuration
There are only a hand full of switches and a single trimpot which can be used to con-
figure the Br-ANA. Once these are set, you will probably never need to adjust them
again. Most of the configuration is done through the Software Configuration, which is
described in the following section.
A) Address
(Two Rotary Switches)
These two rotary switches on the front of the Br-ANA are used to set the
DMX-512 address for the outputs and the location on the RS-422 serial port
where this card will be found. Normally, only one Br-ANA (or other) card is
set to use any one address. If more than one card is set to the same ad-
dress, then the serial ports cannot be attached to the same RS-422 multi-
drop network at the same time. Overlapping addresses wonʼt cause any
damage, but you will get garbled data as both cards try to respond to the
same configuration commands.
If no AutoDownload file has been sent to the Br-ANA, then the Br-ANA
will default to using the address set by these switches as the DMX-512/
Serial RealTime address for the outputs as well as the RS-422 serial ad-
dress. Normally the DMX-512/Serial RealTime address of the outputs is set
by the AutoDownload file which has been sent to the card.
An option under the configuration menu allows you to choose these
switches, the address found in the AutoDownload file, or an arbitrary ad-
dress you set for the address of the first output of the Br-ANA.
The RS-422 serial address for the Br-ANA is set using Hexadecimal
numbers on these switches. The first digit of the Hexadecimal address is set
on the upper of the two switches. The second digit of the hexadecimal ad-
dress is set on the lower of the two switches. If you are not sure how these
translate from decimal numbers, a chart at the end of every Gilderfluke &
Company manual will show you the equivalent numbers.
B) Write Protect Switch
(Slide Switch)
When this switch is ʻWrite Protectʼ position, the Br-ANA will protect the
onboard flash memory and configuration EEprom from accidental altera-
