Makito X User’s Guide, v2.2, Issue 02 325
When a remote client is connected, the state will show up as CONNECTED and the IP
address of the client will be displayed.
The statistics are divided in two sections: network and serial.
• The network stats show what is going in terms of the TCP connection with the remote
controller, i.e., how many bytes were received from and sent to the remote controller.
• The serial stats show how many bytes were sent to the serial device connected to the
encoder and how many were received from it.
In normal operation the number of bytes received on the TCP connection would match the
number of bytes sent on the serial port and the number of bytes received on the serial port
would match the number sent on TCP. However, if the device connected to the Makito
X
sends serial data when no client is connected, these numbers won't match.
Additional stats can show up under special conditions, as explained below:

Statistic Description
Network dropped
bytes
This counter shows the number of bytes received on the
encoder's serial port that could not be sent over the TCP link.
The network connection will always be orders of magnitude
faster than the serial port connection so this statistic is seldom
seen.
Serial Dropped
bytes
This counter shows the number of bytes received on the
network connection that could not be sent on the serial link.
Again if the controlling remote device and the encoder are set
to the same baud rate, it is unlikely that the encoder would
receive data at a rate that can’t be accommodated. If,
however, the baud rates don’t match and the remote device is
set to a higher value, this could occur. In that case, it is a good
idea to reconfigure the remote device or use flow control.
Flow Control Stats
When flow control is used, the network section of the stats will
display the number of XON and XOFF control bytes sent to
the remote device over TCP. This indicates whether or not
data from the controlling device was sent too fast to be
forwarded to the encoder’s serial port. When flow control is
used, the Makito
X will queue up to 2 seconds of serial data at
115,200 bps locally from the remote device. If the remote
device also supports XON XOFF (otherwise, do
not
use flow
control), this ensures that no data is ever lost from it.
