To setup a Riecktron Modem, you can send it this SMS
Part 1 is for RS232 and Part 2 is for RS485:

Updated SMSes for Riecktron modems:

For RS232 (in one SMS)

APN:internet

IP:{Your server IP or FQDN here}

Port:{Enter port received from PNPScada here}

Mode:client

INT:30

IDX:1

BAUD:9600

Reset

For RS485 (in one SMS)

APN:internet

IP2:{Your server IP or FQDN here}

Port2:{Enter port received from PNPScada here}

Mode2:client

INT2:30

IDX2:2

BAUD2:9600

Reset

Explanation of SMS functions:

APN: Usually 'internet' if a normal sim is used. But other APNs are supported by the modems.

IP: Your servers IP or FQDN that you need the modem to connect to

Port: Enter port received from PNPScada here

Mode: 'Client' means the modem will actively try to connect to above IP and Port. 'Server' means modem will sit passive and wait for the server to initiate the connection.

INT: As far as I understand the amount of seconds between connection attempts when modem is in 'Client' mode

IDX: '1' for using the RS232 pins to the meter, '2' for using the RS485 pins to the meter. (You can technically connect IDX:2 and IDX2:1, that means that the first sms above will be RS485, and the second will be RS232, but that gets very confusing. It is recommended that you use IDX:1 for RS232, and IDX2:2 for RS485, like above smses.

BAUD: Baud rate of communications to the meter. Usually 9600.

You can also send either INFO or INFO2 to the later generations of modems to get the modem to reply to you with current settings. (Sim in modem will need an SMS bundle or airtime for this to work)

Note: You can use both RS232 and RS485 of the modem at the same time (pointing them to different ports of your server on PNPScada). But this requires you to load more than one sim and modem in PNPScada, and can get a bit much to keep track of.
