13. DMXB PAT Patch the 96 dimmer (PWM) outputs to any DMX B input channel.
Refer to the DMXA PAT menu for further information.
The DMXA PAT menu is used to patch dimmers to DMX A input channels, while the
DMXB PAT menu is used to patch dimmers to DMX B input channels.
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 5 minutes of inactivity and save.
15. DC PATCH Configure the dimmer to channel patch for the dimmer rack.
Each of the 96 dimmer (PWM) outputs can be assigned and patched to any of the 96
control channels. Multiple dimmer outputs may be patched to a single control channel.
The dimmer to channel patch is used by other menu features to provide transparent
control of the dimmer output circuits. CD-3000 systems are typically patched for 1 to 1
operation but may be altered for custom applications.
Press EXECUTE to enter the menu.
D01<C01 Displays the dimmer (D) output (01) and its current control channel (C) patch (01).
D96<C96 Press MENU ( ) to select the desired dimmer output from 01 to 96.
D96 C96< Press EXECUTE to toggle the pointer (<) to select the control channel to patch.
D96 C01< Press MENU ( ) to select the desired control channel from 01 to 96.
D96<C01 Press EXECUTE to toggle the pointer (<) to select another dimmer output.
Press ESCAPE to exit the menu and save the desired dimmer channel patch.
Press RESET to exit the menu without saving.
The menu will automatically timeout after 5 minutes of inactivity and save.
NOTE: DMX O/P must be set to OFFSET mode for this menu to function.
16. DIM CURV Configure the dimmer curve for each output.
There are four different dimmer curve profiles that can be assigned to each individual
dimmer output circuit. Square Law (SQ) curve is the industry standard and the default
for all dimmers. Linear (LN) curve modifies the dimmer output for a linear relationship
to the control input level. Direct Drive (DD) curve is not modified - meaning the control
input level is directly proportional to the control output level. Non-Dim (ND) curve
assigns the dimmer circuit to operate in a full-on or off state only, with no dimming.
Dimmers set for non-dim will be triggered full-on at 55% control input and will be
triggered off again at 45% control input.
Press EXECUTE to enter the menu.
DIM01 SQ Displays the dimmer (DIM) output (01) and its current dimmer curve.
DIM96 SQ Press MENU ( ) to select the desired dimmer number from 01 to 96.
DIM96 LN Press EXECUTE to toggle to linear (LN) curve mode.
DIM96 DD Press EXECUTE to toggle to direct drive (DD) mode.
DIM96 ND Press EXECUTE to toggle to non-dim (ND) mode.
Press ESCAPE to exit the menu and save the desired dimmer curves.
Press RESET to exit the menu without saving.
The menu will automatically timeout after 5 minutes of inactivity and save.
