8. 2 RM SET
Set the two room assignment for each of the dimmer outputs.
This menu is used to assign each of the 120 dimmer outputs to room “A” or room
“B”. Dimmer outputs assigned to room “A” are controlled via the DMX-A input.
Dimmer outputs assigned to room “B” are controlled via the DMX-B input. This
creates separation within the dimmer rack and makes a single dimmer rack function
as though it is two independent dimmer racks. When used in conjunction with the DC
PATCH menu, the dimmer rack can be configured for sequential DMX control of two
rooms, even if the dimmer room assignments are not sequential.
DMX MODE must be set for 2 ROOM operation for this menu to function.
Press EXECUTE to enter the menu and activate 2 RM SET mode.
D 001 A
Displays the dimmer (DIM) output (01) and the room assignment (A).
D 120 A
Press MENU ( ) to select a different dimmer output from 01 to 120.
D 120 B
Press EXECUTE to toggle the room assignment from A to B.
Press ESCAPE or RESET to exit the menu.
Any change in the configuration is automatically saved.
NOTE: Scene mode (SCENESET) will only activate/control dimmers assigned to
room “A”.
NOTE: DMX O/P must be set to OFFSET mode for this menu to function.
9. DMXA TRM
Enable or disable termination on the DMX A input.
Activates and deactivates a 120Ω termination resistor. DMX termination is indicated
on the LCD display when DMX is being received. When the DMX A input is not
terminated (DISABLED) the LCD display will read AXXXBXXX. When the DMX A
input is terminated (ENABLED) the LCD display will read XXXBXXX.
ENABLED
Press EXECUTE to toggle termination from ENABLED to DISABLED.
DISABLED
Press EXECUTE to toggle termination from DISABLED to ENABLED.
Any change in the configuration is automatically saved.
NOTE: Ensure only the last (end-of-line) DMX receiving device is terminated!
10. DMXB TRM
Enable or disable termination on the DMX B input.
Activates and deactivates a 120Ω termination resistor. DMX termination is indicated
on the LCD display when DMX is being received. When the DMX B input is not
terminated (DISABLED) the LCD display will read AXXXBXXX. When the DMX B
input is terminated (ENABLED) the LCD display will read AXXX XXX.
ENABLED
Press EXECUTE to toggle termination from ENABLED to DISABLED.
DISABLED
Press EXECUTE to toggle termination from DISABLED to ENABLED.
Any change in the configuration is automatically saved.
NOTE: Ensure only the last (end-of-line) DMX receiving device is terminated!
11. DMX O/P
Configure the on-board DMX protocol manager for offset or patch mode..
OFFSET mode is typically used for the majority of systems, and is the factory default.
OFFSET mode refers to the DMX start address, with each of the 120 dimmer (PWM)
outputs addressed sequentially from the DMX start address.
PATCH mode provides full flexibility for addressing each of the 120 dimmer (PWM)
outputs. Each of the 120 dimmer (PWM) outputs can be patched to (controlled from)
any DMX input channel from 001 to 512, from either or both of the DMX A and DMX B
inputs simultaneously.
With DMX patch mode activated, any configuration within the ADDRESS, DMX
MODE, 2 RM SET and DC PATCH menus is ignored, and the DMX patch configured
within the DMXA PAT and DMXB PAT menus takes precedence.
When using the system in DMX patch mode, it is strongly recommended to printout the
patch using a hand held infrared printer (Johnson System Inc., Part Number: JS-IP).
