I have a project where data was read from PLC using a Siemens TC65 modem and MJ20-PRG module and now the intention is to replace the TC65 modem with Teltonika's RUT906 and read data via RS232 serial communication.
The problem is that Teltonika cannot connect via serial communication to Jazz. Tested using the Modbus Poll program.
The serial port settings are defined in the program and power supply added to pins 1 and 6.
Are there any settings that can be used to specify that the MJ20-PRG is used for RS232 serial communication?
