D i s p l a y
The display intensity (
P E R S
>
d I N T
) setting controls display brightness. Select
A U T O
for automatic display or
manually set the intensity to a level from
1 0
to
1 0 0
.
The display on/off setting (
P E R S
>
d I S P
) determines whether the display remains on (
O N
), remains on for 2
minutes after the last key press (
2 M N
), or for 10 minutes after the last key press (
1 0 M N
).
To flip the display, press [Up] and [Down] simultaneously.
L a m p
There are two settings that modify lamp control: Automatic Lamp On (
P E R S
>
A L O N
) and DMX Lamp Off
(
P E R S > D L o F
).
When
A L O N
is
O F F
, the lamp remains off until a “lamp on” command is received. When
A L O N
is
O N
, the lamp
strikes automatically after the fixture is powered on. When
A L O N
is set to
D M X
, the lamp strikes automatically when
the fixture receives DMX data, and it extinguishes 15 minutes after DMX data is lost.
When
A L O N
is set to either
O N
or
D M X
, the automatic lamp strike timing is staggered to prevent all lamps from
striking at once. The delay is determined by the fixture address.
The DMX Lamp Off (
D L o F
) setting allows you to enable (
O N
) or disable (
O F F
) the DMX command that switches
off the lamp. The special combination of DMX values listed on page 14 allows you to execute the lamp-off command
even when disabled.
D M X r e s e t
The DMX reset (
P E R S > d R E S
) setting controls the behavior of the reset command. When set to
O N
, the command
is fully enabled. When set to
O F F
, the command is disabled to prevent accidental resets. When set to
5 S E C
, the
command must be sent for five seconds.
Readouts
T i m e
I N F O > T I M E
provides readouts of fixture hours (
H R S
), lamp hours (
L H R
), and lamp strikes (
L S T
). Under
each item is a resettable (
R S E T
) increment counter and a non-resettable (
T O T L
) counter for total accumulated
hours/strikes since fabrication. To reset an increment counter, display it and then press [Up] until it reads 0.
T e m p e r a t u r e
I N F O > T E M P
provides readouts of the head and base temperature in Celsius and Fahrenheit.
F i r m w a r e v e r s i o n
I N F O > V E R
displays the version number of the installed firmware. The firmware version is also displayed briefly at
startup.
D M X
The DMX log (
d M X L
) menu provides useful information for troubleshooting control problems.
R A T E
displays the DMX refresh rate in packets per second. Values lower than 10 or higher than 44 may result in
erratic performance, especially when using tracking control.
q U A L
displays the quality of the received DMX data as a percentage of packets received. Values much below 100
indicate interference, poor connections, or other problems with the serial data link that are the most common cause of
control problems.
S T C O
displays the DMX start code. Packets with a start code other than 0 may cause irregular performance.
The remaining options under
d M X L
display the DMX values received on each channel. If the fixture does not behave
as expected, reading the DMX values can help you troubleshoot the problem.
