e. The Port number will now appear as a five-digit
number. If you do not wish to change it, press ENTER.

III. Operation
In operation, the MCS-3800, MCS-3400 or MCS-3000 with a
920394 Ethernet Interface Card behaves as a TCP server,
operating on the set IP address and port number. It is
necessary for a client to establish a TCP connection with the
MCS-3800, MCS-3400 or MCS-3000 before anything else can
take place. Once a connection has taken place, operating a
control will cause a packet to be sent to the client. A message
from the client will be reflected by fader position, LED state,
or LCD message on the MCS-3800, MCS-3400 or MCS-3000.
All messages within the TCP packet are the standard MCS-
3800, MCS-3400 or MCS-3000 messages as published in the
developer documents.
