14. SH TIME Set the DMX status hold time from 0 to 99 minutes or infinite.
When DMX is disconnected the system will hold the status of the last received DMX
levels for the selected amount of time. When activated, the LCD display shows a
countdown of the status hold time or infinite hold.
Press EXECUTE to enter the menu.
HTIME 00 Displays the current DMX status hold time (HTIME) setting.
HTIME 99 Press MENU ( ) to set the desired hold time from 00 to 99 minutes.
HTIME XX Press MENU ( ) to set the desired hold time to infinite (XX).
HTIME 00 Press both MENU ( ) switches to toggle back to status hold time of 00.
Press ESCAPE to exit the menu and save the desired DMX status hold time.
Press RESET to exit the menu without saving.
The menu will automatically timeout after 2 minutes of inactivity and save.
15. DC PATCH Configure the dimmer to channel patch for the dimmer rack.
Each of the 24 dimmer control outputs may be assigned and patched to any of the
24 DMX control channel inputs. Multiple dimmer control outputs may be patched to a
single DMX control channel input. The Dimmer to Channel Patch (DC-PATCH) is used
by other menu features to provide transparent control of the dimmer output circuits.
The default DC-PATCH for DE90-3000 Series retrofit control systems is 1 to 1,
meaning dimmer control output 1 is controlled by DMX control channel 1, dimmer
control output 2 is controlled by DMX control channel 2, and so on thru 24. The
default patch is for normal operation of a full 72" DE90 dimmer rack consisting of 12
x dual dimmer modules with a total of 24 dimmers or a small 36" DE90 dimmer rack
consisting of 6 x dual dimmer modules with a total of 12 dimmers.
The DC-PATCH will need to be modified (programmed) to compensate for a mixture
of single, dual or quad dimmer modules. Once the DC-PATCH has been modified the
dimmers should have sequential DMX control in most applications.
In a full 72" DE90 dimmer rack there are 12 locations for dimmer modules. Each
dimmer module can contain a single dimmer circuit or dual dimmer circuit. The first
dimmer module location at the top of the rack is hard wired to dimmer control outputs
1 and 2... the last dimmer module location at the bottom of the rack is hard wired to
dimmer control outputs 23 and 24.
In a small 36" DE90 dimmer rack there are 6 locations for dimmer modules. Each
dimmer module can contain a single dimmer circuit, a dual dimmer circuit, or a quad
dimmer circuit. The first dimmer module location at the top of the rack is hard wired
to dimmer control outputs 1, 2, 13 and 14... the last dimmer module location at the
bottom of the rack is hard wired to dimmer control outputs 11, 12, 23 and 24.
Examples of DC-PATCH configurations can be found on page 9 and 10.
Charts used to determine the DC-PATCH can be found on page 11 and 12.
