Q : Does the performance of a RS-232/485 device become faster when it's moved onto the Internet/Ethernet network?

¡@

Ans : It depends on your application.

For the traditional RS-232/485 application, it may become slower.

Traditional time used : RS-232/485 transmit time ( C )

New time used : Internet/Ethernet transmit time + RS-232/485 transmit time ( A+B+C )

( All of the TCP packets need a extra ACK packet to commit the transmit action. This also causes a little delay in the communication. )

For the Xserver application, it may become faster.

Users can write their own Xserver application to acquire and compress data, and then transmit this large amount of data at one time to receive better performance.

Traditional time used : RS-232/485 transmit time ( C * n modules )

New time used : Internet/Ethernet transmit time ( A + B )

For more information, please refer to the 7188E/8000E user's manual.
