I am trying to use an iTach Ethernet to Serial adapter (IP2SL) to remote control my Panasonic PA-AE6000E. But it seems that the projector does not show any reaction, there is no response on the RS232. Nothing. I have tried several methods of communication but it simply does not happen anything:
1. iRule by using the available PT-QE4000 codes that are available in the software. The codes seem to be the same as in the manual for the PT-AE6000E. --> the projector does nothing
2. I wrote a quick programm in node.js that opens a socket connection to the iTach and port 4999 and send the string manually. --> the projector does nothing
3. I have used a little helper programm from the iTach company (GScan.exe) that connects to the iTach and lets you send strings via a windows GUI to the device --> the projector does nothing.
There is even no response with an error code or similar, the communication is absolutly dead.
When using methods 1-3 communication with the iTach via TCp itself works fine. ITAch is responsive and it will send responses via TCP when connected to socket 4998 as it is supposed to when I use its API calls. But when connected to socket 4999 which should simply route strings untouched to the RS232 --> nothing happens.
I am using a 1:1 9 pin serial cable. I have also tried a crossed cable (nullmodem cable) but this changes nothing.
Serial commmunication is configured according to the Panasonic requirements (SERIAL,1:1,9600,FLOW_NONE,PARITY_NO).
Any ideas what's going wrong?
