DMX control
Overview
DMX is a digital control protocol widely used in entertainment and architectural
lighting. Any DMX controller meeting the DMX-512A standard, may be used to
control the machine. A controller that is RDM compliant will be able to program
and monitor some settings of the machine remotely.
When a DMX signal is present, the machine’s stand-alone functions
do not work. To control the machine locally the DMX controller must
be powered off or disconnected.
If the DMX signal is removed (controller turned off or unplugged), the
machine will revert to its previously stored RUN MODE settings.
If the machine was set to OFF, it will revert to this state.
If the machine was set to STANDBY, it will revert to this state.
If the machine was set to TIMER, it will revert to this state.
If the machine was set to CONTINUOUS, it will revert to this state.
Connection
The JEM ZR series machine provides 5-pin XLR connectors on the rear of the
machine for DMX connection.
For best results, use cable designed for high speed digital data transmission.
DMX functions
The JEM ZR series DMX start address must match the DMX start address
assigned to it on your controller. To set the address, see “Setting the DMX start
address” on page 16. The machine has two DMX personalities, requiring one or
two DMX channels. The mode is set using the two RECEIVE options in the LINK
menu, or via RDM. (Prior to firmware 1v4, only 1 channel was used.)
When the machine is at running temperature and is under DMX control it
displays DMX (+ the current DMX base address).
The DMX control values are shown in the table below.
