1 Mitsubishi Alarm Modems at a Glance Mitsubishi Alarm Modems are new automatic modems with a large data memory, several func - tions and integrated Internet technology. They are designed as intelligent communication com - puters with a 32-bit power CPU and a 2 MB non-volatile Flash memory.
2 Function overview 2 . 1 Integrated PLC pr otocols Mitsubishi Alarm Modems can communicate directly with the PLCs of leading manufacturers using the relevant PLC protocol, and access PLC variables, markers and ports via the PLC pro - gramming interface.
2 . 4 T eleservice via PC A Mitsubishi Alarm Modem can be used to handle the remote maintenance of several controllers via a telephone line. This is usually possible with the program - ming software in use. The variables and I/O ports of the PLC can also be read or written remotely online with the Mitsubishi Alarm Editor (MX-AME).

3 . 4 Connecting the GSM antenna (only GM series) First of all find a suitable location for mounting the GSM antenna outside of the control cabinet. In order to find a suitable location with a good reception quality you may use the software MX Mitsubishi Alarm Editor to display the signal quality.
3 . 5 Inser ting the SIM card (onl y GM series) To insert the SIM card in the modem, open the SIM card holder on the Mitsubishi Alarm Modem by pressing the small button on the right of the holder with a pen or a pointed object. You can now carefully pull out the card holder and insert your SIM card.
3 . 6 Connection to the T elephone Network (onl y AM series) Connection to telephone network (PSTN) is established via the included telephone cable and the “Line” jack of the MAM. To get access to your Mitsubishi Alarm Modem, the telephone number of the connection used must be known.
4 Interfaces The serial interfaces COM1 und COM2 are to connect a PC, a PLC or other devices. NO TE The type and number of interf aces av ailable depend on the type of modem being used. (see section 2.6 and 10.6). 4 . 1 COM1 – RS232 (Jack) The RS232 interface COM1 (9-pole D-Sub socket) is provided on all Mitsubishi Alarm Modem models.
4 . 3 Mitsubishi Alpha XL and Mitsubishi FX at RS232 4.3.1 A l p h a X L The Mitsubishi Alpha XL is to be connected to the COM ports of the Mitsubishi Alarm Modems (MAM): 쎲 d i r e c t l yb yt h e“ A L 2 - G S M - C A B ” c a b l et oC O M 1 쎲 by the “AL2-GSM-CAB” cab le and the “Red Adapter” (see chapter 10.
Access to the DIP switc hes A DIP switch is provided for selecting the operating mode at the RS485/422 interface. This is located on the right of the COM2 connection terminal and is accessible after the cover is removed. Interfaces RS485 / RS422 Mitsubishi Alarm Modem 4-3 - + COM1 (R S4 COM2 (RS422 / 485) P ower Process Line Data out DC 1 0.
Setting the operating mode on the DIP switch NO TE RS485 stipulates that the cables should be ter minated at both ends of the transmission sec - tion. The termination prev ents signal reflections in the cables and in times of no data trans - mission, enf orces a defined idle state on the bus.
RS485 4-wire connection (4-wire bus system, full-duplex) The terminals of the 2 twisted-pair cables are wired in the same way as for the RS422 connec - tion. Both twisted-pair cables must be terminated if the Mitsubishi Alarm Modem is installed at the start or end of the bus cables.
5 Power supply After all installation steps are completed, switch on the power supply to the Mitsubishi Alarm Modem. The modem got two power supply connectors: Two screw terminals and a power sup - ply jack (pin diameter 2,1 mm, inner diameter 6 mm). E A TTENTION: P ower U = 10 – 30VDC! Ensure the correct polarity of the power suppl y terminals.
6 Operation Once all installation steps have been completed, you can start operating the Mitsubishi Alarm Modem. Self-test after power up The Mitsubishi Alarm Modem carries out an extensive self-test after the power supply is switched on. All the LEDs will switch on for test purposes and all three types of memory are checked.
Mitsubishi Alarm Modem is operational The device is operational once the self-test is completed and it has “started working”. Line-LED when functioning correctly (onl y GM series) The Mitsubishi Alarm Modem GSM is logged in if the green Line LED flashes at regular intervals.
7 Configuration and projects 7 . 1 Initial configuration You can regard a Mitsubishi Alarm Modem (MAM) in the same way as you would consider a PC with an operating system and many communication programs. After the initial power up, the task memory is empty and the MAM “doesn’t know” what it is meant to do.
7 . 4 . 3 PIN OK, no netw ork, MAM not logged in The MAM cannot be logged in if there is no network reception available for the provider con - cerned, even if the PIN that has been entered in the project for the inserted SIM card is correct. The Line LED will not flash and will remain off.
7 . 5 Operating modes: Modem M ode and TiXML Mode TiXML Modus Mitsubishi Alarm Modems (MAM) can handle a wide range of tasks automatically. These tasks are written and configured in TiXML, a variant of the XML standard. This operating mode is called TiXML Mode.
7 . 5 . 5 Activ ating/deactivating Modem Mode In Modem Mode, a MAM operates like a normal modem and establishes connections with the conventional AT command: “ATDT 0123456789”. The MAM must, however, be switched beforehand from TiXML Mode to Modem Mode.
8 Software 8 . 1 MX Mitsubishi Alarm Editor MX-MAE MX-MAE is a user-friendly Windows software for configuring MAM functions such as alarms and messages, as well as the reception/sending of messages and the reading of logged data. You use the mouse to configure the recipients, messages and PLC variables for alarm mes - sages.
8 . 3 Remote Access If you are using a PLC programming software to configure and control your PLC, you can also make use of its functions remotely by software MX-MAE.
9 Communication with a PLC Mitsubishi Alarm Modems can communicate with a PLC in two different ways: 쎲 The Mitsubishi Alarm Modem can speak the language of your PLC . T echnical feature: The required PLC driver is integrated in the Mitsubishi Alarm Modem.
