Cannot get feedback to work

Post by DemoIan » Mon Feb 21, 2022 9:01 pm

I am struggling to get feedback to work on a centro 8, I have setup a CYP CR-KP2 keypad as a device, it uses Telnet to communicate, I can send commands to the keypad and if I use app feedback then I get an automated response but not the response I programmed in the keypad.

I have tried using the web interface, telnet, command in demopad and physically pressing the buttons but is seems the Centro doesn't see any feedback.

It should be a simple setup, the keypad sends a telnet command e.g.

KP1-K1-BLUESOUND\x0D\x0A

the Centro receives it and sets a flag

Does anyone have experience of these keypads, is telnet the best way to communicate? Any help would be gratefully received

I cannot connect to the Centro using Telnet, is this normal behaviour?

Yes this is expected, the Centro does not act as a telnet server, it typically acts as a client to control other devices

Looking at the manual that came with the unit, it differs from the on line manual all the telnet commands need to be suffixed with \0xd, i have tried this but still no luck, might try another port number.

Fixed!....... painful, Telnet commands have to be suffixed with \x0d but the feedback needs \x0d\x0a

Used Hercules to see what came back, the manual contradicted the online manual.
