Get Parameters
Router parameters are held within registers. Each register contains 2 bytes of information. For simplification, the number of registers for storing numbers is 2, while the number of registers for storing text information is 16. The register numbers and corresponding system values are described in the table below:
| REQUIRED VALUE | REGISTER NUMBER | NUMBER OF REGISTERS | REPRESENTATION |
|---|---|---|---|
| System uptime | 1 | 2 | 32 bit unsigned integer |
| GSM signal strength (dBm) | 3 | 2 | 32 bit integer |
| System temperature in 0.1 degrees Celcius | 5 | 2 | 32 bit integer |
| System hostname | 7 | 16 | Text |
| GSM operator name | 23 | 16 | Text |
| Router serial number | 39 | 16 | Text |
| Router MAC address | 55 | 16 | Text |
| Router name | 71 | 16 | Text |
| Current SIM card | 87 | 16 | Text |
| Network registration | 103 | 16 | Text |
| Network type | 119 | 16 | Text |
| Digital input 1 | 135 | 2 | 32 bit integer |
| Digital input | 137 | 2 | 32 bit integer |
| Current WAN IP address | 139 | 2 | 32 bit unsigned integer |
| Analog input | 141 | 2 | 32 bit integer |
Set Parameters
The Modbus daemon also supports setting of some system parameters. For this task the Write holding register command is used. System related parameters and how to use them are described below. The register number specifies where to start writing the required values. All commands, except “Change APN”, accepts only one input parameter. For the APN the number of input registers may vary. The very first byte of APN command denotes a number of SIM card for which set the APN. This byte should be set to 1 (in order to change APN for SIM card number 1) or to 2 (in order to change APN for SIM card number 2).
| VALUE TO SET | REGISTER NUMBER | REGISTER VALUE | DESCRIPTION |
|---|---|---|---|
| Digital output 1 (ON/OFF) | 201 | 1/0 | Changes the state of the Open collector (OC) output (1 -ON; 0 - OFF) |
| Digital output 2 (ON/OFF) | 202 | 1/0 | Changes the state of the Relay output (1 - ON; 0 - OFF) |
| Switch WiFi (ON/OFF) | 210 | 1/0 | Switches WiFi ON or OFF (1 - ON; 0 - OFF) |
| Switch mobile data connection (ON/OFF) | 211 | 1/0 | Switches mobile data connection ON or OFF (1 - ON; 0 - OFF) |
| Switch SIM card | 212 | 0/1/2 | Switches SIM card in use (1 - SIM1; 2 - SIM2; 0 - SIM1 → SIM2 or SIM2 → SIM1) |
| Change APN | 213 | APN code | Changes APN |
| Reboot | 220 | 1 | Reboots the router |
