Questions on 634XE-USB´s


New member

Some of the following questions may sound stupid to you, but we are new with LCD´s. We are in the professional broadcast business.

Question 1:
Is there any "dummy" software available which will - set or operator controlled - allow prompting of various 1 / 2 / 3 / 4-line messages in intervalls of 10 - 60 seconds to the display(s).
The messages itself should be preprogrammeable in advance.
We need something like a simple and easy to use playout software (ideally multichannel), where 100 - 1000+ messages are prompted to the display event-by-event.

Question 2:
Will you be able to provide your 634XE USB-Series with 4 keys?
We would like to prompt the messages in various formats / languages.
Key 1 = format/languages 1
Key 2 = format/languages 2

Question 3:
Will the USB on your 634XE USB-Series also power your unit?

Question 4:
Have you made any experience how many 634XE USB units you will be able to hook-up via a hub to one control system?
Any power supply problems?
Any communication problems?

Your earliest reply on all this is highly appreciated.

It is really simple to write software to talk to these displays. There is an example that reads data from a file and sends it to the display here.

The CFA-634XE does not have keys. It could be done but would require tooling.

The CFA-634XE is powered by the USB.

Each CFA-634XE takes less than 500mA. Typically, if you have a powered USB hub there will not be any trouble.
