Serial Data Statistics Menu
This screen provides a summary of port activity for both serial data
ports. These values will be reset to zero after a reboot cycle.

(Both COM1 and COM2 will be shown)
• Bytes in on port—Number of bytes received by the
transceiver through the serial interface
• Bytes out on port—Number of bytes transmitted by
the transceiver through the serial interface
• Bytes in on socket—Number of bytes received by the
transceiver through the IP socket
• Bytes out on socket—Number of bytes transmitted by
the transceiver through the IP socket
In general, the number of bytes Out on Socket should
follow the number of bytes In On Port as all bytes
received on the serial port should be transmitted out to the IP
interface. The same should be true in the opposite direction,
bytes Out On Port should follow bytes In On
Socket.
• Clear Com1 Statistics—Resets counter to zero.
• Clear Com2 Statistics—Resets counter to zero.
2.5.3 IP-to-Serial Application Example
You have a choice to use UDP or TCP to establish communications.
This will depend on the type of device you are communicating with at
the other end of the IP network. In this example we will use TCP to illus-
trate its use.
In TCP mode, the transceiver remains in a passive mode offering a
socket for connection. Once a request is received, data received in the
serial port will be sent out through the IP socket and vice versa, until the
connection is closed, or the link is interrupted. The TCP session has a
timeout of 10 minutes. If inactive for that time, it will be closed. The
