Gilderfluke&Co Z-Brick - Manual (Page 8)

On the Front of the Z-Brick:
A) Output LEDs: 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 Z-Brick are ‘Open Collector, Switch To
Ground’, you can ground out any output pin, and the appropri-
ate 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.
B) Fuse LEDs: The thirty-two outputs of the Z-Brick are divided into
four, eight bit ‘channels’. Each of these channels is fused for ap-
proximately 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 caus-
ing the fuse to open. The fuses are actually ‘PTC fuses’, which act
more like circuit breakers. Once the overload is removed, they
reset.
C) Update LED: This LED will flash on each update from DMX-512 or
the Z-Buss. It shows you the the Z-Brick is receiving data OK.
D) DMX-512 LED: This LED will be lit when the Z-Brick is receiving
DMX-512 data. DMX-512 reception can be disabled by moving
the ‘DMX-512 Disable’ jumper to the ‘disabled’ position.
E) Address Switches: The address for the Z-Brick is set using
Hexadecimal numbers. 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..
F) Z-Buss: This twenty pin IDS connector is used to connect one or
more Z-Bricks to the ONE card that is sourcing data. This ‘sourcing’
card can be a BR-ANA, BR-EFB, BR-SmartMedia, or any other
Gilderfluke & Co. card with an appropriate Z-Buss output. The BR-
ANA, BR-EFB, or BR-SmartMedia outputs data from the DMX-512 or
serial input or onboard Flash Memory to this connector. The
pinouts of this connector is as follows:
