4102A - RS-232 DMX/PMX converter - ordering code: 4102A
Why is it so difficult to get DMX data out of a PC?
There is no standard interface doing the required transmission speed and a DMX transmission has to be repeated continuously,
and this takes an enormous amount of time if the host CPU (the PC processor) has to take care of this. |
Two possible solutions come to mind: using an intelligent interface, such as our cards 1512B or 1512C , which free the PC's CPU
from computing time, or using a protocol that transfers only data changes, similar to MIDI.
That protocol is called PMX (Pulsar Multiplex), a serial communications protocol to transfer high resolution data to a standard
serial port. Many products of Pulsar and Clay Packy can receive and interpret PMX data directly without need for an additional
interface. PMX is based on the serial port RS-232 (modem/mouse port), while DMX is using the symmetrical RS-485 standard. |
PROTOCOL CONVERTER
The interface card 4102A is a protocol converter, converting serial PMX (RS-232) to serial DMX (RS-485) and vice versa,
DMX to PMX. As serial port drivers are available in all computer operating systems and all programming lan,guages, no special
driver is needed to get the 4102A card to work. A documented monitor program to watch data flow on the PMX port is available
from out support website free of charge. |

INTERNET SUPPORT SITE
Please visit our support site www.pcdmx.com for downloads, drivers, demos and more information on PC interface cards
and other PC DMX interfaces.
As more and more software vendors are supporting the interfaces as standard output devices, we have also set up a
"third party software" page, which is dedictaed to commercially available programs. |
