transceiver will offer again the port for connection after this time. In this
mode, the entraNET 900 behaves the same, whether it is an Access Point
or a Remote. (See
Figure 2-16 and Table 2-1 )
Establishing a
Connection
From the PC, establish a TCP connection to the IP address of the
Remote transceiver and to the IP port as configured above (typically
30011). A Telnet client application can be used to establish this connec-
tion. Data can now be sent between the PC and the RTU or other con-
nected device.

Example
Once the transceivers are configured and the changes have been exe-
cuted, they begin processing any data presented at the
COM
ports. Data
presented at the Access Point’s
COM
port will be packetized and sent via
UDP to the Remote. Upon receiving the packet, the Remote strips the
data out of the UDP packet and sends it out its
COM
port. Likewise, data
presented at the Remote’s
COM
port is packetized, sent to the Access
Point, stripped, and sent out the Access Point’s
COM
port. Note, this
configuration does not use multicast addressing.
