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 teminated (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 24 dimmer (PWM)
outputs addressed sequentially from the DMX start address.
PATCH mode provides full flexibility for addressing each of the 24 dimmer (PWM)
outputs. Each of the 24 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).
Press EXECUTE to enter the menu and configure the DMX mode.
DISABLED This menu is disabled to help prevent inadvertent changes. Proceed to enable.
ENABLED Press and hold MENU ( ) and MENU ( ) at the same time for 4-5 seconds.
OFFSET Press EXECUTE to toggle the DMX mode from OFFSET to PATCH.
PATCH Press EXECUTE to toggle the DMX mode from PATCH to OFFSET.
Press ESCAPE or RESET to exit the menu.
Any change in the configuration is automatically saved.
12. DMXA PAT Patch the 24 dimmer (PWM) outputs to any DMX A input channel.
There are two ways to configure the DMX patch. Each of the 24 dimmer (PWM)
outputs can be manually (MANUAL) patched to a DMX input channel, or patched in
blocks (BLOCK) of sequential dimmers and DMX channels.
For MANUAL patching, each of the dimmers are patched individually. First, the
dimmer (DIM) output is selected, and then any DMX input channel from 001 to 512 is
patched to the selected dimmer.
For BLOCK patching, a sequential range of dimmers are patched to a sequential
range of DMX channels. First, the first dimmer number (DIM#) in the block is selected,
then the DMX A start address (DMXA) for the block is selected, and then finally the
number of dimmers (#DIM) in the block is selected. For example, if DIM# is 001, DMX
is 001, and #DIM is 024, then all of the dimmer outputs, 001 thru 024 are addressed
sequentially to DMX channels 001 thru 024.
For a more complex example, if DIM# is 007, DMX is 321, and #DIM is 012, then
dimmer outputs 007 thru 018 are addressed sequentially to DMX channels 321 thru 344.
Using a combination of MANUAL and BLOCK patching methods can speed up
configuration. Typically, a BLOCK of dimmers is first patched and then edited using
the MANUAL patch.
The DMX patch should be cleared (CLEAR) before configuring the patch. Clearing
the patch ensures all previously configured patch data is cleared (erased).
When DMXA PAT is utilized in conjunction with DMXB PAT, each of the 24 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.
