2. Description of router MG100 Functions

2.1. GPRS part

MG100 uses OEM modules manufactured as standard for GPRS communication. The GPRS module is connected to the computer part of the device via the RS232 serial port. Diagnostics and settings of the GPRS module are gradually improved in the MORSE network in line with improvements in software for GPRS modules, see PPP-GPRS protocol for MORSE.

2.2. Modem part

The control microcomputer has 4 MB of FLASH memory and 16 MB of RAM memory available. The battery, real time backup supply, detector of supply voltage failure and watch dog circuits belong amongst the other circuits of this block. If there is a supply voltage failure the fact is recorded into memory with the respective time data thanks to the charge stored in electrolytic capacitors. The user therefore has information available about the time and duration of possible faults caused by power failures. It is possible to connect equipment with signalling rates up to 115.2 kbit/s to the modem via the RS232 data interface. RS232 interface converters are protected against overvoltage with TRANSIL elements. A lithium battery is used for backing up in the modem part.


Owing to the use of lithium batteries in the modem part it is not recommended to store them for a period of longer than 2 years.

2.3. Supplying

The router is supplied by the DC current 13,8 V. The consumption in the quiet state is from 200 to 260 mA according to module used, the consumption at transmitting is up to 350 mA. The router can be set in the SLEEP mode when the consumption drops down to 2,5 mA. The return in the active mode can be done by the signal inputting on the serial port or after a preset time.

2.4. GPRS router assembly

Routers MG100 are special devices which require skilled assembly. All supplied equipment is assembled by RACOM at the user’s site. For subsequent maintenance RACOM specially trains the user’s skilled staff and as an additional aid provides them with Operating regulations for radio data networks and MORSE Firmware – Documentation.


CAUTION! Danger of explosion upon replacing the incorrect type of battery. Follow the manufacturers instructions for handling used batteries.
