innovators for industry
To Use C++ Remote Interface Wrapper:
(1) Create a derived class of NetworkAdapter.
(2) Create a datagram socket (UDP) with the
IP address of the desired RTC6 Ethernet Board
and port 63750
(1)
.
(3) Implement the platform specific socket
functionality in the virtual functions send / recv
/ select .
(4) Create an RTC object and pass
NetworkAdapter implementation.
