7.4 Serial Gateway
Figure 93: Serial Gateway – sample topology
The router’s serial gateway function lets you establish serial connectivity across the Internet
or with another network. Serial devices (meters, PLC, etc.) can then upload and download
data. (See Fig.
Configuration is done in the
Configuration
section,
Mobile WAN
, with the
Expansion Port 1
item for RS232, or
Expansion Port 2
for RS485. In this example, the RS232 interface of the
router is used.
Mobile WAN configuration
Mobile WAN configuration is the same as in the previous exam-
ples. Just insert the SIM card into the
SIM1
slot at the back of the router and attach the antenna
to the
ANT
connector at the front. No extra configuration is needed (depending on the SIM
card used). For more details see Chapter
Expansion Port 1 configuration
The RS232 interface (port) can be configured in the
Config-
uration
section, via the
Expansion Port 1
item. (See fig.
.) You will need to enable the RS232
port by checking
Enable expansion port 1 access over TCP/UDP
. You may edit the serial com-
munication parameters (not needed in this example). The important items are
Protocol
,
Mode
and
Port
. These set the parameters of communication out to the network and the Internet. In
this example the TCP protocol is chosen, and the router will work as a server listening on the
2345 TCP port. Confirm the configuration clicking the
Apply
button.
