CR300 webpage through a router modem

Benjamin.vial May 25, 2020 05:44 AM


I've made a bash script to retrieve data on campbell data logger with the URL API. The script works fine for ethernet links but not (yet) for the serial link.

For example, I have a CR1000 and a CR300 on the same router. The CR1000 is connected with a NL120 to use ethernet network with the router, and the CR300 use serial /USB converter plugged on the router.

On the router I set firewall rules :

URL_of_the_router:4080 -> reditect to (IP of the cr1000 and port 80, so this is the webpage).

URL_of_the_router:2000 -> reditect to the USB converter, so the CR300. But I cant differenciate which is the response port, if I want the web page (and so use the URL API) of the CR300, I don't know how to setting this in the CR300.

I don't know if it's even possible.

Have you an idea ?

The HTTP service in the datalogger is bound to the TCP/IP stack in the datalogger and cannot be served over, what is to the datalogger, an RS-232 connection.  Your best bet is to configure a PPP/RS-232 link between the datalogger and the router.

Ok thanks for your answer, so I'll test the PPP link.
