9.2.2.5 Socket number
When command messages are sent to the PTC-150, it is normal to send the next command
message after waiting for the completion message or error message to return.
As the completion message or error message also has a socket number, it indicates which
command has ended.
The ACK message is not returned for these commands and inquiries, and only the completion
message of socket number 0 is returned.
9.2.3 VISCA Device Setting Command
Before starting control of the PTC-150, be sure to send the Address command and the IF_Clear
command using the broadcast function.
