Product description

The Netkom ES75 terminal is a compact GSM/GPRS/EDGE modem for the transfer of data, SMS and faxes in GSM networks. The Netkom ES75 terminal supports the EDGE standard and thus permits a far higher data transmission rate up to 236.8 kbps. Packet-oriented data transmission and a permanent online connection enable rapid data access and transmission rates. Industrial standard interfaces and an integrated SIM card reader mean it can be used rapidly, easily and universally as a quad band GSM/GPRS modem. Its performance band width and the robust housing make it easier to quickly implement new applications in areas such as telemetry and telematics.

The features, functions and interfaces of the modem Netkom ES75 are described below.

The functionality of the modem corresponds to the features of the MC75 module, to which a SIM card reader, an RS232 interface, an mini USB interface and a greater supply voltage range have been added.

All the external interfaces of the modem are integrated permanently in the housing. The plug-in connections are standardised and suitable for use under vibration.

Switching

on modem

Startup

Before startup, the components required for your application must be connected. The SIM card must be inserted in a deenergized state. The modem is ready for operation when supply voltage is applied and the ignition line is activated. If the recommended plug-in power supply unit is used, the ignition line is already connected to the supply voltage line, and the modem is thus immediately switched to the active state. It starts the network search and registers with network operator. Please read the following conditions for switching the modem on and off:

Simply applying supply voltage (+ to pin 1 and GND to pin 6) alone is not enough to switch on the modem.

It can be switched on in two different ways:

Activation of the IGT_IN ignition signal on the power supply connection

The switching regulator is switched on with the IGT_IN = high signal. When the switching regulator is switched on, VBAT is generated as the operating voltage for the GSM/GPRS module. This still does not activate the GSM/GPRS module. Triggered by VBAT, a transistor switch generates the IGT ignition signal with a delay of approx. 100 ms for the GSM/GPRS module. Only then is it switched on. (It exits the POWER DOWN operating state.)

25

Startup

In its energized state, the GSM/GPRS module provides the supply voltage (VDD). VDD ensures that the switching regulator remains on, even when its closing condition is lost (i.e. IGT_IN = low).

Explanation: VBAT = operating voltage for the module VDD = supply voltage from the module

Activation of the RS232 or USB control line DTR

The modem can be switched on in the same way as via IGT_IN by activating the RS232 control line DTR (high signal).

Note

The modem is switched on immediately using the recommended plug-in power supply unit (see the above explanation on startup).

26

Switching off

/ resetting the

modem

The modem can be switched off in two different ways:

Using a software command by means of an AT command

A software shutdown via an AT command is always advisable for a controlled shutdown of the modem. In this case, the GSM/GPRS module signs off before the watchdog condition results in the speciﬁc switching off of the supply voltages.

www.nwm.pl

Startup

Activation of the PD_IN reset signal on the power supply connection

The POWER DOWN line on the GSM/ GPRS module is connected to the watchdog input pin of the power supply ASIC, which can only be switched off by changing the watchdog condition. To do this, the PD_IN modem reset line is active (high) for at least 3.5 s. This results in immediate, “hard” disconnection, with the modem unable to sign off correctly from the base station in the STANDBY and TALK operating states. In the case of this hardware shutdown, the software is no longer able to respond before the voltage is switched off. This corresponds to a direct, unannounced disconnection of the operating voltage. In the application you can switch off or reset the module without interrupting the input voltage supply.

Note:

Usually, the network search takes only a few seconds till the modem is registered. If the ﬂashing continues, this means that no SIM card is inserted, no PIN number is entered or no GSM network is available.

POWER DOWN

Once the operating voltage is applied (+ and GND), the modem is in the POWER DOWN state.

The operating voltage for the GSM/GPRS module is disconnected (the switching regulator is off). In other words, the software of the GSM module is not active.

A transition to the POWER DOWN state always occurs in the following circumstances:

When the modem (module) is shut • down by means of AT commands (e.g. sleep mode). When the external reset line is active.•
