Dear technical department

I recently purchased 2 units of the RDC6445S controller to install on two laser cutting machines
and I have some questions to ask.

1 - What is the function of the IN1 input of the CN2 connector?

2 - Where can I find updated firmware for my controller?

3 - The RTlink port is a standard RS232 (+12v/-12V) or TTL port?

4 - I work with large parts on my machine. I need a keyboard with just pulse, start, stop and directional controls

on the other side of the machine. What protocol can I use to send these commands via RTLink?

5 - Is there any RTLink port protocol documentation to download?

Thanks in advance
