Most polled protocols are best served by UDP services, as the protocol
itself has built-in recovery mechanisms (error correction). UDP pro-
vides the needed multidrop operation by means of multicast addressing,
where multiple remote devices receive and process the same
poll message.
On the other hand, TCP services are best suited for applications that do
not have a recovery mechanism and must have the guaranteed delivery
that TCP provides despite its extra overhead. The IP-to-Serial example
shows how to do this. See “IP-to-Local Serial Application Example” on
Page 121.
To configure either of these services, use the Serial Configuration Menu
(Figure 3-22 on Page 57).
To configure IP-to-remote serial services, use the Remote Serial
Gateway Menu (Figure 3-28 on Page 64).
Configuration
There are several configuration parameters for the remote serial gateway
found under the Serial Configuration Menu. Note that some of the
parameters are not applicable to IP-to-serial mode. After making
changes to the configuration, you must use the Commit Changes option to
cause the transceiver to implement the requested changes.
If you are connecting EIA-232 serial devices to the transceiver, review
these parameters carefully.
Serial Configuration Wizard
The Serial Configuration Wizard, available through the Local Serial
Configuration Menu, is recommended for configuration of serial ports.
The Wizard uses a step-by-step process that eliminates conflicting set-
tings and streamlines complex configurations.
