The GPRS MMS-04 modem for management of street lighting in the Gorsvet-KS system is externally very similar to the MMS-03 modem. Only the internal stuffing (it on the basis of the WAVECOM Q64001 module) and a modem configurator changed. It is LAID OFF! KMD-1 is REPLACED!
Still the MMS-04 modem is intended for work as a part of the ACS systems of our firm (management of traffic in the ASUDD-KS system, management of street lighting in the Gorsvet-KS system). It is structurally executed in the form of a box for installation on a DIN lath.
MMS-04 provides a packet transmission 800/900/1800/1900 MHz given in networks of cellular communication, a class 10. Packages are transmitted through the voice channels which are not used at present, the transfer priority (a voice traffic or data transmission) is chosen telecom operator.
The modem has the external antenna and is powered directly from a network 220B, consuming 6 W. On a case of loss of a network the reserve accumulator is provided. The device has two ports RS-485 for contact with other devices. During the work in the ASUDD-KS system one of ports can work in the ASS-UD protocol (100 Hz, L1,L2), other equipment can be connected to the second port (for example, the computing module). At the same time the modem begins to carry out functions of the coordinator as allows to load into itself plans of coordination. During the work in the Gorsvet-KS system one port RS-485 is used. Also there is exit 12B 100ma (it is marked by U and GND) for a zapityvaniye of external devices. One more port - miniUSB - is used in the technological purposes (installation of the driver and service software is necessary). Functioning at negative temperatures is ensured by the built-in heater.
To the user modems are delivered previously configured. It needs to buy SIM cards of local mobile operator (3B or 1,8B), to include the service GPRS on the chosen tariff and or to turn off check of the PIN code (from the menu of the ordinary cell phone), or to specify this PIN code in a configurator. After that SIM cards are installed in each device. In the territory of the Russian Federation we recommend the services Beeline, MTS or, as a last resort, Megafon (inconvenient tariffs). The object registers in system ASUDD-KS or "Gorsvet-KS" according to the programmed identifier.
Unlike MMS-02, MMS-03 the modem can be executed in special execution. It is in addition possible to establish bluetooth (for a possibility of a remote configuration, for example, without removing from a column) and the holder of the SD card (for record of the magazine, for example). The issue of support of two SIM cards is handled.
