CP4 TCP Connection

 

I am trying to control a Kramer KDS box from a CP4. I can connect to the KDS in PUTTY set to RAW. When I connect a TCP client in SIMPL, I get the connected feedback and a connected analog response from the box, but no actual communication. Is there something I'm missing to make this work? the NVX units that were ordered still won't be here for months. Thanks in advance.
 

Hi,
on which port do you connect the TCP Client??
Some protocols need a special handshake.
I'll upload a module for the telnet handshake in a minute, maybe that helps.

These Kramer boxes are telnet on port 5000, right?
If you telnet from laptop you get responses and everything?
 

I will check it out, thanks.
 

Martin,
Yes 5000. Yes, PUTTY at port 5000 using RAW protocol. the most perplexing thing it that the Crestron will establish and keep a connection. Just no data back and forth.
 

Just following up on this thread - Bill concluded there were no issues.
The command was just accidentally being sent on RX$ instead of TX$ during testing.
