Questions for LCD 633 cabling


New member
Hello all,

I would like to implement a project which needs a remote control of a (self written) computer program (to record and play music).

Since I need a keypad for controling the program I probably will use the CFA633 LCD Module.

So here are my questions:
.) Depending on the used cable - how far can the remote control be from the pc?
The maximum specified serial cables distances about 15 metres (50 feet) - this could be not enough for my project.
So maybe better (and cheaper) could be the connection with an RJ-45 cable (see previous thread) - is the info posted there usable for 633 series also?

.) Do I need an extra power supply for this display or can it be powered over long distance (20-30 meters - 60-100 feet) through this cable?

Thank you for any answers,
