3. Connecting, configuring and management

3.1. Connecting, operating mode

Only individual s with specialized techni cal training and those who hav e studied the pr oduct specifications
are permitted to assemble (install) the modem.

Before connec ting the dev ice insert the SIM card into the modem . In order to install the SIM card do the
following:

Eject the SIM holder by pressing the SIM card holder ejector button (Fig. 2.1);
Pl ace the SIM card into the SIM car d holder;
I nsert the SIM card holder with the SIM card into the modem.

Be careful when instal ling the S IM card. Connect the GSM ant enna and the c ommuting cabl e. Modem has
two interfaces t o connect control dev ice: RS232 and USB. The modem can be controlled by both int erfaces
simultaneously.

Power the modem with the power connector (Fig. 2.5.2). When usi ng the USB interface you need only
connect the US B-cable. The frequent blinking of t he green LED indi cates that the m odem is turned on (T able

2.6.1). Remov e the PIN code of the SIM card to complete automatic online registration.

Note: GSM antenna, commuting cables and the power supply unit are not incl uded i n the set.

To work with USB i nterface, install US B driver on your PC. USB driver you can fi nd at www.irz.net. After
installing the driver should you see several ports on your PC:

SimTech HS-USB Modem 9000 — the main port for management with AT-commands and data

transferring;

SimTech HS-USB AT Port 9000 — the port for management with AT-commands, if the main port is

transfer dat a;

Sim Tech HS-USB Diagnostics 9000 / SimTech HS-USB NMEA 9000 — service ports.

With removed SIM card’s PIN code, the network registration is automatic.

3.2. Management, rebooting and turning off

Connecting and conf iguring iRZ ES90iPU modem to access the I nternet from your PC is same as f or a
standard modem. If you using RS232 interface, select “standard modem 33600 bps”. For modem management
with industrial applications, use standard AT-commands. Description of AT-commands can be downloaded
from the website www.irz.net.

The modem can be rebooted using one of following ways:

eight transitions of the DTR COM-port line into a passive state (DTR < -2V); the duration of the

impulses and pauses between the impulses should remain within the range of 100-500 ms;

applying a positive pulse (10 V to 20 V), the duration of at least 50 ms to 4 pin of power connector

(Section 2.5. 2);

rebooting after a giv en period of time (WD interval, turned off by default ), setting is done in the menu

mode;
by using AT-c ommand “AT+CF UN=1,1”;
temporary power shutdown.

Turning on the modem:

by using AT-command “AT+CPOF”;
power shutdown.

AT-command “AT+CFUN” is turn on energy-saving mode of the modem. For more detail see AT-

commands description for the GSM module.

3.3. Menu mode

The menu mode’s f unction i s to change the m odem’s param eters and access the statisti cs. In thi s menu,
the power of the GSM m odule is switched of f. After leaving the m enu mode automati c rebooting t akes place.
The menu m ode can be accessed f rom the operation m ode. Before accessing t he menu mode connect the
modem to the computer (speed: 115200 bit/sec, 8-N-1), run Hyper Terminal or a similar program to
communicate with the modem.

The modem will go into the menu mode:

Menu mode:

Variant PU-05

<P1> View statistic

<P2> WD interval = OFF

<PC> Power control

<PR> Clear statistic

14

Variant XX — software version.

Symbols <P…> stand for control commands. A command is sent af ter pressing “Enter”. If an incorrect
command has been sent, the “ERROR” message appears. Entering commands is case-insensitive.

After entering the “P1” command a transition into the submenu of statistics occurs:

Statistics:

Power_Modem = XXX

Bad_Power_Modem = XXX

Power_Module = XXX

Bad_Power_Module = XXX

Reset = XXX

where is:

Power_Modem — number of times the modem has been turned on;

Bad_Power_Modem — number of times the modem power supply has deviated from the allowed;

Power_Module — number of times the power supply of the GSM module has been turned on;

Bad_Power_Module — number of times the modem power supply has deviated from the allowed;

Reset — number of resets.

After the statistics appears the transition to the main menu occurs.

Use “P2” command to proceed to the WD submenu:

WD interwal,hh (WD OFF: hh=0, max: hh=255)

<Q> Quit

WD interval =

15

To change the reboot interv al, enter a number from 0 to 255 (by pressing “Enter”). The reboot interval is set
in hours. If you need to switch off this functi on enter 0. Keep in mi nd that after the set interval expires, the
unconditional reboot of the modem will occur. In case i ncorrect information is entered the modem displays
“ERROR” and off ers the W D submenu once agai n. In case cor rect i nf ormation is entered or < Q > command is
sent a transition into the main menu takes place.

After input f the <PC> command – you can view the control voltage (accuracy of measurement 5%):

If the modem power supply from the power connector, then

POWER Uin: 11.7 Umd: 3.8 V

If the modem power supply from the USB connector, then

POWER Uin: USB

Umd: 3.8 V

where Uin — control internal voltage, Umd — voltage ( V) to GSM module.

After the output a transition into the main menu occurs.

After entering the “PR” command a transiti on into the submenu of clearing the statistics occurs:

Clear statistic?

<Yes> Yes

<Q> Quit

The accumulated stat istics is cleared by t he <YES> command. I n case incorrec t inform ation is entered the
modem displays “ERROR” and offers the submenu of clearing the statistics once again. In case correct
information is entered or <Q> command is sent a transition into the main menu takes place.

After entering the <M> command the main menu appears.

The exit f rom the menu mode oc curs after the SIM-tray is i nstalled back agai n. The modem goes int o the
working mode.

3.4. Programming mode

Program “m prog” is used to change or update software of the managing micr ocontroller of the m odem.
Figure 3.1 shows an external view and main features:
1 – language, 2 – working with ports, 3 – worki ng with Flash, 4 – working with EEPROM , 5 – start button,
6 – view window.

Fig. 3.1. Main view

If within 10 seconds after powering the device an update has not started, the modem will leave the
programming mode and enter the menu mode.

To change the software do the following:

1. Start the program

Close all programs, which can use the port you will connect to the modem.

2. Click the

button in “Port” frame;

3. Choose the number of the COM port where the modem will be connect ed

4. Connect the modem (without the SIM holder) to the computer and turn on the modem;

Turn on the modem. T he m odem will go i nto t he program mi ng m ode. T he green LE D wil l blink: 250ms on /
250ms off. “Open” button (not later than 10 sec once the modem was powered).

4. Emerge ncies

To facilitate the use of the modem, tracking and display of emergencies are provided.

4.1. Emergency 1 (incorrect input power supply)

Emergency 1 occur s when the i nput p ower sup ply devi ates f rom the perm issibl e value. The modem stops
working and it shuts down the G SM module power. A perm anent red LED signals that the emergency has
occurred. The recovery is possible only when the input power supply is re-established.

4.2. Emergency 2 (incorrect module power supply)

Emergency 2 occurs when the GSM module power supply deviates from the permissible value. The modem
stops working and i t shuts off the GSM modul e power. A red LED signals that the emergency has occurred
(0.5s on / 0.5s off). The recovery is possible only if the module power supply is re-established within 10
seconds after the em ergenc y occurred. If withi n 10 seconds the m odul e power supply r em ains incorr ect ( with a
correct input power supply), the modem goes into the waiting mode meaning that the modem’s power suppl y is
turned off, t he emergency i ndicati on is preserv ed. T he waiting mode c an be t erminated only after the power is
completely disconnected.

4.3. Emergency 3 (GSM module failed to start)

Emergency 3 occurs if the GSM m odule does not t urn on or i s absent. A r ed LED signal (0.25s on / 0. 25s
off / 0.25s on / 1s off) turns on after a precise determination by the modem of the emergency situation
(~15 sec). The recovery is possible onl y af ter a successf ul launch of the G SM module. After 10 unsucce ssful
attempts to launch the module, the modem goes into the waiting mode meaning that the modem’s power
supply is turned off, the em ergency i ndi cati on i s preserv ed. T he waiti ng mode can be t erm i nated onl y af t er t he
power is complet ely disconnected.

In case of repeated emergency after the modem is turned back on, the modem should be serviced.
