The BR-SmartMedia doesn’t actually believe that it has been

set to act as a 'Smart' Brick until it receives a valid message

through the 'Smart' Brick Network. In the unlikely event that you

switch from 'Smart' Brick to 'Dumb' Brick mode while a BR-

SmartMedia is running, there will be a delay of ten seconds or so

before it starts acting as a 'Dumb' Brick.

4) J8 Power: If the BR-SmartMedia is acting as a 'Dumb' Brick, then

this switch is used to select whether the ‘J8’ power for the optoiso-

lators is provided by the same power supply as the BR-

SmartMedia, or is provided by an external isolated source. When

operating as a 'Smart' Brick, this switch has no effect.

When plugged into any Gilderfluke & Co. Brick card cage, this

will be brought out on a RJ-12 connector on the card cage.

There should never be both ‘Smart’ and ‘Dumb’ Bricks in the same

card cage. They share the same pins on the edge connector and

backplane. Damage may result if both are installed in the same

card cage.

There are four optically isolated digital inputs which can be

used to start, stop, pause or select specific show sequences to

play. Facing the end of the wire, with the latch upwards, the

pinout of a standard ‘J8’ cable is as follows.

Any event can be triggered on either the ‘closing’ or ‘opening’

edge of any input. A ‘closing’ is when you apply a voltage to an

input. An ‘opening’ is when that voltage is removed. The inputs

can be triggered on any voltage from 12 to 24 VDC. If you don’t

have an external source of power for these two inputs, you can

‘steal’ some juice from the BR-SmartMedia’s power supply connec-

tions. Just put the ‘J8 Power’ switch in the ‘Internal’ position.

5) J6 Power: If the BR-SmartMedia is acting as a 'Dumb' Brick, then

this switch is used to select whether the ‘J6’ power for the optoiso-
