Problems communicating with sony fcb h11 block camera - VISCA protocol

Projects Interfacing w/ Software on the Computer

Hello everyone,

Overall Objective:
Controlling Sony FCB H11 Block Camera using USB to RS232 and wireless transmission device and VISCA protocol.

Current Objective:
For now, I'm just trying to establish communication with the camera, and execute a zoom command when I press a button.

Problem:
I am not getting any response from the camera.
I am sending data from PC to nanoDDL, which further, through wireless transmission, is obtained at camera through microraptorHD. When I test whether the data is transmitted/received, the respective user interface for the transmitter and the receiver shows that the data is correctly send and received. But the camera shows no response i.e. I'm not getting the acknowledgement about the data. I am able to get the video but I'm not able to zoom-in.

Thank you very much in advance and let me know if I can provide any other information.

You can provide the code and circuit diagram as something OTHER than stupid Word docs.
