i'm using the dmxusbpro object (from nullmedium.de) to run an Enttec DMX usb pro Mk2. with my particular setup i seem to be experiencing an issue whereby DMX information is only sent on DMX channels 1 and 2.
here's the exact text i conducted (after installing the external and necessary drivers):
1. open dmxusbpro.maxhelp
2. send "menu" message to [dmxusbpro] to populate the umenu
3. choose the item "/dev/cu.usbserial-ENVWHY17" in umenu. this opens the Enttec device
4. open the [fadercontrol] patcher
5. move the position of the sliders. with sliders 1 and 2 the DMX information is sent with no problem. for all other sliders (3-16) no information seems to be sent.
MacBook Pro 2.4 GHz 4GB
FTDI drivers installed:
both D2XX 1.2.2 and VCP (FTDIUSBSerialDriver) v2.2.18
has anyone else experienced a similar issue and if so, any suggestions for resolving it? i wonder if maybe i'm overloading the bandwidth, i already tried sending message "channels 4" to the dmxusbpro object (because i only need 4 channels), this does not change the behaviour. i know this is not a hardware issue because when i pilot the Enttec using Enttec's Pro-Manager utility (a tedious test because you have to first remove the VCP driver), i get response on all DMX channels, not just 1 and 2.
thanks in advance!
