DMX-512 Master component
A serial based communications protocol designed for controlling theatrical equipment such as dimmers, fog machines and intelligent lights. DMX-512 Slave devices are daisy chained together with a final 180R terminating resistor at the end of the chail. DMX requires the signal to be level shifted from VCC and GND to +2.5V and -2.5V.

Examples
DMX Master Example, reads the value of two ports using switch arrays to set the values and then transmits the data in a DMX packet.
For DMX 512 slave example see: Component: DMX 512 Slave (Comms: System)

Serial Properties |
|
Channel |
| UART Channel selector Software channels are bit banged using generic I/O pins but are not as reliable as hardware channels. Hardware channels use the selected peripheral on-board the target microcontroller. | |
|
|
Baud Options |
| Baud rate option selector | |

| Pin to be used for Transmit data | |
|
|
DMX Properties |
|
Data Channels |
| Number of data bytes used by the DMX chain, Max 512 bytes per transmission. 24 Bytes minimum to match minimum 1204us timing requirements, not all channels need to be used. | |
|
|
Simulation |
|
Scope Traces |
| Selects if the scope traces are automatically added to the data recorder window or not. Simulation - draws an approximation of the UART data onto the scope trace. ICT - sets up the scope trace for incoming data and adds UART packet decoding at the correct BAUD. | |
|
|
Console Data |
| Selects if the console data is automatically generated or not | |
|
|
Console Columns |
| Number of characters that can be displayed on a single line of the console. | |
|
|
Data Source |
| Simulation data source used to allow the component to connect to various remote devices Nothing - Simulation data is ignored COM port - Routes the communication data to and from a physical or virtual COM port Injector - Routes the communication data via a data injector component on the Panel. | |
