connection is closed, or the link is interrupted. In this mode, the trans-
ceiver behaves the same, whether it is an Access Point or a Remote.
(See Figure 3-31 and Table 3-1)
NOTE: The TCP session has a timeout of 10 minutes (600 seconds). If
inactive for that time, it will be closed. The transceiver will
offer the port again for connection after this time expires.
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 (30010—
COM1, 30011—COM2). A Telnet client application can be used to
establish this connection. Data can now be sent between the PC and the
RTU or other connected 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.
