Extron device

Any datasheet ? I would like to see it. Maybe you need to read the datasheet of the so call "Extron device"

Ok... You want to send ---> ! Is it ASCII code ? or a binary code ? If I have a device to received a data, I need to know :

Baud rate
8 bits
Parity or Not
Stop bits
Start bits

So your device is : 9600 baud - 8 bits - no parity - 1 stop bit OK
Code sequence into the device ? Answer in the datasheet <-- Maybe ASCII into the device ? Answer in the datasheet <-- Maybe

You see what I mean ....
