<strong>GSM</strong> модем <strong>iRZ</strong> <strong>MC52iT</strong>User Manual3. Connection and Setting Up3.1. ConnectionBefore feeding the power supply you need to install the SIM card in the <strong>modem</strong> (the SIM cardmust be enabled). To do this, you need:· to extract the SIM tray by pressing the SIM tray extract button (Fig. 2.4.1);· to install the SIM card into the SIM tray;· to insert the SIM tray with the SIM card into the <strong>modem</strong>.No strong physical efforts must be applied while installing the SIM card.Connect the <strong>GSM</strong> antenna to the antenna connector, as well as the commutating cable (RS232).Feed power supply to the <strong>modem</strong> through the connector RJ11 (Fig. 2.4.2).Note: <strong>GSM</strong> antenna, data cables and electrical power unit are not included in the complete setconfiguration.After the power supply feeding, registration occurs automatically, which is signaled by the greenindicator frequent flashing. After the registration is completed, the <strong>modem</strong> jumps to the operatingmode, the green indicator flashes less frequently (Table 2.6.1).3.2. Control, Restarting and Power OffThe <strong>modem</strong> control is performed by standard AT commands. For additional information andsupport visit the manufacturer’s site – www.radiofid.ru.Modem restarting can be carried out by the following ways:· by the program method through AT commands,· by eight jumpings of the DTR COM port line into passive state (DTR < 3V), duration ofpulses and the pauses between the pulses must lie within the range <strong>10</strong>0-500 ms,· by temporary power-off.The <strong>modem</strong> can be powered off using the following ways:· by the program method, using AT commands (escape to the power standby mode);· directly by power-off.After power-off made by means of AT commands, the <strong>modem</strong> escapes to the power standbymode (minimum power consumption). Escaping from the power standby mode is performed uponthe DTR of the COM port.11
