7. CONFIGURATION IN TYP. SITUATIONS

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. 93.) To use this function the router model must have a serial interface (port).

Options include RS232, RS485-232 or RS232-485-ETH.

Conﬁguration is done in the Conﬁguration section, Mobile WAN, with the Expansion Port 1

item (or Expansion Port 2, for RS422 and RS485). In this example, the router is equipped with

an RS232 interface (port).

Mobile WAN conﬁguration Mobile WAN conﬁguration is the same as in the previous ex-

amples. 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 4.3.1.

Expansion Port 1 conﬁguration The RS232 interface (port) can be conﬁgured in the Con-

ﬁguration section, via the Expansion Port 1 item. (See ﬁg. 94.) You will need to enable the

RS232 port by checking Enable expansion port 1 access over TCP/UDP. You may edit the

serial communication parameters (not needed in this example). The important items are Pro-

tocol, 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.
