Chapter 1: Introduction and Product Description Safety Warnings Handling Precautions All devices must be handled with certain precautions to avoid damage due to the accumulation of static charge. Although input protection circuitry has been incorporated into the devices to minimize the effect of this static build up, proper precautions should be taken to avoid exposure to electrostatic discharge during handling and mounting.
Chapter 1: Introduction and Product Description RF Interference Issues It is important to follow any special regulations regarding the use of radio equipment due in particular to the possibility of radio frequency, RF, interference. Please follow the safety advice given below carefully. • Switch OFF your Wireless CallFinder when in an aircraft. The use of cellular telephones in an aircraft may endanger the operation of the aircraft, disrupt the cellular network and is illegal.
Chapter 1: Introduction and Product Description AT Commands The AT commands listed below are those supported by the CallFinder CF100 unit when its VOICE/DATA switch is in the VOICE position. These are Multi-Tech-specific AT commands. Command Values Description ATI ATI1 AT&F AT>AD=p ---p = 0 or 1 ATDnA AT>AD? n is phone number of up to 10 digits -- Returns model number of CallFinder unit. Returns CallFinder’s software version. Resets parameter values to factory defaults.
Chapter 2 – Getting Started Step 1. Obtain a Wireless Account Obtain a GSM Network Account 1. Contact your GSM network agent to obtain an account and/or SIM card. Be sure to specify if you want a data only, voice only or voice and data account. 2. Provide the agent with the CallFinder’s model number and IMEI number. Both are located on the label on the bottom of the product. You will also need to provide information about billing and about the wireless services/features you need. 3.
Chapter 2: Getting Started Step 2. Set Voice/Data Switch and Connect Antenna, Serial Cable, & Power Voice/Data Switch Be sure that the VOICE/DATA switch is in VOICE position before connecting the power cord. The VOICE/DATA switch should always be in the VOICE position. The DATA position is for future potential products. Antenna Connect a suitable antenna to the SMA connector. An antenna is supplied with each unit.
Chapter 2: Getting Started Front Panel LEDs Once the power is connected, the LEDs on the front panel will present information about the CallFinder’s wireless modem functions, including signal strength. CallFinder LED Descriptions RI RING INCOMING - Indicates an incoming ring from the wireless module. CD CONNECT DATA – This LED is not used as it is for future potential products. LS LINK STATUS - This LED blinks when there is network activity between the carrier and the cellular module.
Chapter 2: Getting Started A3. Establish a named HyperTerminal ‘connection’ to the CallFinder. A4. Select the command computer’s available COM port that is physically connected to the CallFinder. Click OK. A5. At the “COMx Properties” screen, set the connection parameters to these values: Bits per second = 115200 Data bits: = 8 Parity: = none Stop bits: = 1 Flow control= Hardware Click Apply and click OK. Click OK again when the “COMx Properties” screen returns. Multi-Tech Systems, Inc.
Chapter 2: Getting Started A6. At the HyperTerminal prompt, type AT and press Enter. The CallFinder will return the response OK, thus confirming that the CallFinder is communicating with the command PC. At this point, the communications program is set up for steps 3B and 3C below. 3B. Verify Signal Strength B1. In the command window, type AT+CSQ B2. The modem responds with the received signal strength (rssi) in numeric form. The meaning of the number returned is shown in the table below.
Chapter 3 – Wireless Antennas The Antenna The antenna sub-system and integration in the application is a major issue. Many parameters of the antenna are variable (type, length, performances, thermal resistance, etc.). These elements can affect performance characteristics like sensitivity and emitted power. GSM Antennas The CallFinder’s antenna connector is an SMA connector. The SMA connector incorporates a 'Screw-on’ action in order to make the connection easier. It also gives excellent RF performance.
Chapter 4 – Wireless CallFinder Application Options Prerequisites: A. You must have a valid and activated SIM chip from your wireless service provider B. Be sure the VOICE/DATA switch is in the VOICE position. C. You will need a serial-to-USB2.0 adapter if your command computer lacks a serial port (see step 2). 1. There are four common setups for the CF100FX2-G unit, as shown in the table below. Identify the situation in which you will use the Wireless CallFinder. CallFinder connects to...

Chapter 4: Wireless CallFinder Application Options Connection Situation #3: CF100 to Analog Station Port on PBX Caution: When connecting a CF100 CallFinder to an analog station port and allowing incoming calls through that CallFinder, the PBX must be configured to prevent the incoming caller from using the CallFinder’s secondary dial tone to make calls to a third party. Such ‘call-through’ activity could be expensive to the PBX owner.

Set CallFinder’s Interface to FXO. Use HyperTerminal (or other communications program) to check the current Interface setting, to change the Interface to FXO if necessary, and to confirm that change. 2. Connect Cables. Connect an RJ11-to-RJ11 cable between the telco POTS line and the CF100 FXO port. 3. Purpose.
Chapter 5 – Troubleshooting General Troubleshooting Tips 1. Be sure that the RJ11 cable is plugged into the CallFinder telephony connector that is appropriate for your application (either the FXS or the FXO interface). 2. To check which interface type your CallFinder is set for internally, use a terminal program (like HyperTerminal) accessed at your command computer (connected from serial port on computer to RS-232 connector on CallFinder).
