send a show to the BR-MultiBrick32 while the Write Protect

switch is in the ‘locked’ position.

5) Record: This LED is turned on whenever a revision 1.nn BR-

MultiBrick32 has had its ‘Record Enable’ button pushed. It indi-

cates that the BR-MultiBrick32 has had its DMX-512 and 'Smart'

Brick Network ports disabled and the RS-422 port enabled. This LED

must be ON to talk to the BR-MultiBrick32 through the RS-422 seri-

al port.

In revision 2.00 and later BR-MultiBrick32 hardware there is no

‘Record Enable’ button. The RS-422 port, BrickNet, and DMX-512

ports are always available. This LED will light whenever the card is

being configured and flash when it is receiving an AutoDownload

file.

6) Output LEDs (Revision 2.00 and Later Cards Only): These thirty-

two LEDs show the current status of the thirty-two digital outputs. If

a LED is lit, then that output is ‘ON’. Because the outputs of a BR-

MultiBrick32 are ‘Open Collector, Switch To Ground’, you can

ground out any output pin, and the appropriate LED will light. This

can be useful when diagnosing output wiring problems. If you are

commanding ‘on’ an output and you don’t see a LED, then the

output is probably drawing too much current and the output is

‘self protecting’. Disconnect the load and see if the LED now

lights. If it does, then it definitely is an overload problem. If it does

not, then try turning ‘on’ some of the other outputs. if they light

OK, then the output driver might be damaged. If they do not,

then verify your addressing and retest.

7) Fuses (Revision 2.00 and Later Cards Only): The thirty-two out-

puts of the BR-MultiBrick32 are divided into four, eight-bit ‘chan-

nels’. Each of these channels is fused for approximately one Amp

of continuous current. These four LEDs light to show if the four

fuses are OK. If any are out, then a short circuit (or too heavy of a

load) is dragging the outputs down and causing the fuse to open.

The fuses are actually ‘PTC fuses’, which act more like circuit

breakers. Once the overload is removed, they reset.
