network. To install the SIM cards:
1. Power off the unit and unplug the power cord. Do not under any circumstances remove protective
power supply cover. Harmful voltages may be exposed if cover is removed, and can lead to electrical
shock and or death.
2. Electrostatic discharge (ESD) is the release of stored static electricity that can damage electrical
circuitry or components. Static electricity is often stored in your body, and discharged when you come
in contact with an object of a different potential.
Perform the procedure below (removal of chassis cover) described in this section only at an ESD
workstation using an antistatic wrist strap. If such a station is not available, you can provide some ESD
protection by wearing an antistatic wrist strap and attaching it to a metal ground screw (lug) next to
power switch of MultiModem iSMS chassis.
3. Use a small screwdriver to remove the six (6) screws on the back of the MultiModem iSMS as shown by
the red circles below. Then lift the top cover from the back of the unit and then slide towards the front
to remove.
4. Insert the SIM cards into the SIM card slots on the internal wireless modems. Each modem has a
graphic line depicting the correct SIM card orientation. These receptacles are highlighted by the two
red boxes in the illustration below (SF 800 model shown).
5. To re-attach the cover, start with the cover tilted up and align the “teeth” with the gaps between
those on the bottom of the chassis as shown by the red arrows in the illustration above.
6. Rotate the cover down and push towards the rear of the unit until it is flush.
7. Insert the six (6) screws back in to the unit and tighten.

Rack or Wall Mounting (SF 400/800)
The MultiModem SF 400/800 units can be rack (or wall) mounted with screws using the mounting
brackets.
Rack Mounting
Ensure proper installation of the unit in a closed or multi-unit enclosure by following the recommended
installation as defined by the enclosure manufacturer. Do not place the unit directly on top of other
equipment or place other equipment directly on top of the unit. If installing the unit in a closed or multi-
unit enclosure, ensure adequate airflow within the rack so that the maximum recommended ambient
temperature (50° C) is not exceeded. Ensure that the unit is properly connected to earth ground by
verifying that it is reliably grounded when mounted within a rack. If a power strip is used, ensure that the
power strip provides adequate grounding of the attached apparatus.
When mounting the equipment in the rack, make sure mechanical loading is even to avoid a hazardous
condition. The rack used should safely support the combined weight of all the equipment it supports.
Ensure that the mains supply circuit is capable of handling the load of the equipment. See the power label
on the equipment for load requirements.
This equipment should only be installed by properly qualified service personnel. Only connect like circuits
- connect SELV (Secondary Extra Low Voltage) circuits to SELV circuits and TN (Telecommunications
Network) circuits to TN circuits.
Note: The ambient temperature of the rack interior must not exceed 50° Celsius.
19-Inch Rack Enclosure Mounting Procedure
Attaching the MultiModem iSMS to the rail of an EIA 19-inch rack enclosure will likely require two
persons. Essentially, the technicians must attach the brackets to the MultiModem iSMS chassis with the
screws provided, as shown in the figure above, and then secure unit to rack rails by the brackets. Because
equipment racks vary, screws for rack-rail mounting are not provided. Follow the instructions of the rack
manufacturer and use screws that fit.
1. Position the right rack-mounting bracket on the MultiModem iSMS using the two vertical mounting
screw holes.

Obtaining and Activating a Wireless Account
Before you can use the cellular feature, you must obtain a GSM wireless account with an activated SIM card
capable of sending SMS text messages through your service provider. Then activate the account by installing
the SIM into the MultiModem iSMS. Please see the wireless account Activation Notice located on the
MultiModem iSMS CD; follow the directions to complete the activation of your account.
Important Note About Service Provider Fees
Your service provider will charge you for your data usage. Please check with your provider to make sure
you are aware of the charges.
Your MultiModem iSMS can be used to send a large number of SMS messages very quickly, and, as such,
you should have a contract/plan that accounts for the numbers of messages you are likely to send. Multi-
Tech is not responsible for any charges relating to your cellular bill.
Direct Communication to the Cellular Modem
You may want to communicate directly to the cellular modem to activate the modem, verify network
registration, and/or troubleshooting your connection. To do this:
1. Open a PC's command window by clicking the Start button and selecting Run.
2. Type CMD to open the command window. Click OK.
3. When the command window opens, type IPCONFIG.
4. Type Telnet 192.168.2.1 5000 (Note: 5000 is the port number).
See the GPRS AT Commands Reference Guide.
Using AT Commands to Check Network Registration and
Roaming Status
Use this command to verify that the cellular modem has been registered on a wireless network.
1. In the command window, type AT+CREG?
2. The modem will respond in one of the following ways:
Network Registration Verification
Value Network Registration Status
+CREG: 0,0 The modem is not registered on any network
+CREG: 0,1 The modem is registered on the home network
+CREG: 0,5 The modem is registered on a network and it is roaming
Note: If the modem indicates that it is not registered, verify the signal strength to determine if the
problem is the strength of the received signal.

Wizard
Starting the iSMS
Open a Web Browser
1. Be sure that the MultiModem iSMS is cabled and that the power is connected as shown in
Chapter 2.
2. Then open a Web browser.
3. Type the default gateway address line: http://192.168.2.1
4. Press Enter.
Login
The Login screen for the MultiModem iSMS Web Interface displays.
•Type admin (admin is the default user name) in the user name box.
•Type admin in the password box.
•Click Login.
Note: The User Name and Password entries are case-sensitive (both must be typed in lower-
case). The password can be up to 12 characters. Later, you will want to change the password
from the default (admin) to something else. If Windows displays the AutoComplete screen,
you may want to click No to tell the browser to not remember the password for security
reasons.
Password Caution: Use a safe password! Your first name spelled backwards is not a sufficiently
safe password; a password such as xfT35$4 is better. It is recommended that you change the
default password. Create your own password.
Web Interface Opens

Save to Flash Memory
If a connection is established, the settings have been entered correctly, and your basic configuration is
complete; now, you must save your settings to the Flash Memory. Saving to the Flash Memory saves the
current settings in the flash prom and prevents the settings from getting lost at the next power up.
Note: The system will save the SMS settings every 8 hours automatically; however, it will not save the
system settings during this automatic save. The automatic saving of the SMS settings is helpful for those
times when the administrator does not have direct access to the Ethernet port.
Save
Click the Save button to save your system settings to the flash memory.
Restart
This is optional. You do not have to restart the MultiModem iSMS after saving to the flash memory.
