BR-SmartMedia Hardware Configuration

There are only a hand full of switches which can be used to configure

the BR-SmartMedia. 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.

1) Address: These two rotary switches on the front of the BR-

SmartMedia are used to set the address for the RS-422 serial port.

Normally, only one BR-SmartMedia card is set to use any one ad-

dress. If more than one card is set to the same address, then the

serial ports can not be attached to the same RS-422 multidrop

network at the same time.

The RS-422 serial address for the BR-SmartMedia 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 address 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.

2) Write Protect Switch: When this switch is ‘Write Protect’ position,

the BR-SmartMedia will protect the onboard configuration EEprom

from accidental alterations. With the switch in the ‘Write OK’ posi-

tion, reads and writes can take place normally. With the memory

write protected, the BR-SmartMedia should retain whatever has

been configured into it for at least forty years.

3) 'Smart' Brick/'Dumb' Brick Select: (Serial modes Only) This switch

tells the BR-SmartMedia whether the BR-SmartMedia is going to be

acting like a ‘Dumb’ Brick or a ‘'Smart' Brick’. When acting as a

‘Dumb’ Brick, the BR-SmartMedia will be triggered to play shows by

the four optically isolated ‘J8’ trigger inputs. When acting as a

‘Smart’ Brick, The BR-SmartMedia will lock to and follow time code

information send to it through the 'Smart' Brick Network from the

'Smart' Brick Brian.

A single card cage should not have both ‘Smart’ and ‘Dumb’

Bricks installed in it. Damage may result if there are.

This switch actually switches the six wires that connect to the

backplane of the BR-SmartMedia between the optoisolators used

for 'Dumb' Bricks and the RS-422 receivers used for 'Smart' Bricks.

If you plug in a BR-SmartMedia which has been configured to act

as a 'Smart' Brick into a slot that has been configured for a 'Dumb'

Brick, you risk damaging the RS-422 receivers.
