Warning! Do not open connected equipment. Hazardous voltage may occur within this unit when connected to power supply. Prevent access to hazardous voltages by disconnecting the unit from power supply and all other electrical connections. It is necessary to have a GSM subscription from a net-

work operator. They will provide you with a SIM card that should be mounted in the SIM card holder. The SIM card holder is located under the top lid of the unit. Press the button to eject the holder. Mount the SIM card in the holder and make sure it is correctly installed before it is pushed back into the unit. 7.3 Antenna care and placement

Warning, unit contains internal hazardous voltage when power supply is con-

nected. Prevent access to hazardous voltages by disconnecting the unit from power supply and all other electrical connections. Since the GD-01 US is installed in a fixed location, special care must be taken when planning the installation, especially when placing the antenna. The standard antenna shipped with the product is an efficient dual-band antenna designed for the 850 MHz and the 1900 MHz frequency bands used in the US and Canada. Depending on the installation location and surrounding materials, the signal strength reaching the GD-01 US may not be sufficient. The best way to find the optimal position of the antenna is to use the command AT+CSQ that returns the received signal strength. Please refer to the AT-command guide for further information. The antenna must only be connected locally and not connected to a cable distribution system going outside the building. 6696-2230 13 7.4 Connections RS-232 interface, 5-position screw terminal SIM interface Antenna interface, SMA female connector RS-232 interface, 9-pos D-sub Power connection 1236 VDC 14 6696-2230 7.4.1 Power interface 2-pos screw terminal Description No. 1 No. 2 VDC

115.2 kbit/s, 8 databits, no parity and 1 stop bit

(please refer to AT+IPR and AT+ICF commands) RTS / CTS flowcontrol enabled (please refer to AT+IFC command) DTR signal must be active from the DTE (please refer to AT&Dn command) Follow the steps below to get the unit up and running as quickly as possible:

Make sure the power is disconnected from the unit Insert a valid SIM-card with correct services enabled

(e.g. incoming and outgoing DATA service) Make sure that the antenna is connected and placed in the best position possible Power on the unit and make sure that the PIN code of the SIM-card is disabled either with the help of a mobile phone or with the command AT+CLCK. If the PIN code should be enabled make sure to enter the correct PIN code with the command AT+CPIN Check on the front of the GD that the NET LED is flashing, this means that the unit has a connection to the GSM network and that it is registered Check the received signal quality with a terminal program (please refer to AT+CSQ command) The value of the first parameter reported from the +CSQ command should be between 10 and 31, the value of the second parameter should always be 0 Make sure that the DTE equipment is connected and configured with the same serial settings as the GD unit Configure the GD unit with appropriate commands as needed in the specific applica-

tion. Please refer to the application examples found in the AT-command guide Make sure that the DTE equipment is connected and configured with the same serial settings as the GD unit Configure the GD unit with appropriate commands as needed in the specific applica-

tion. Please refer to the application examples found in the AT-command guide 7.7 Configuration The GD-01 US can be configured via industry standard set of AT-commands on the service port interface. For a complete description of all AT-commands please refer to the AT-command guide. 7.7.1 Service port The service port (RS-232 interface) is default configured to:

Serial speed: 115.2 kbit/s Data format: 8 data bits, No parity and 1 stop bit Flow control: RTS / CTS DTR control: ON (AT&D2) 6696-2230 17 8. Functional description The GD-01 US is used for for wireless data transmissions over the public GSM network. It can be used to link PLC:s, data loggers, security and surveillance systems or for data acquisition. The GSM services supported by the Westermo GD-01 US are Circuit Switched Data, Fax, SMS and GPRS. A data communication link can be established to another GSM modem, to an analogue modem or to a digital ISDN adapter.The protocol used when connecting to an analogue modem is V.21,V.22,V.22bis,V.23,V32 or V.34.The protocol used when connecting to an ISDN adapter is V.110. A connection can be established either via AT-commands (ATD) or via the RS-232 signal DTR.The DTR connection is made to a preconfigured number.The unit can send and receive FAX according to Fax Class 2 Group 3. SMS messages can be transmitted or received. An SMS send session can be initiated by either an AT command or by a positive transition of the DTR signal. Sending and receiving of packet data is possible with the GPRS service. GD-01 US 18 6696-2230 9. GSM network operators, subscriptions and services The GD-01 US support several services in the GSM network. In order to get the unit to work properly its important that the GSM service used in a specific application also is enabled on the subscription (the SIM card). When ordering a SIM card from a network operator its necessary to confirm that the specific service needed for the application is enabled before trying to set up the commu-

nication link. The implementations of the networks may also differ slightly from network to network. Hints:

When using a GSM modem in a fixed installation its in most cases a good idea to disable the PIN code on the SIM card. In some GSM operators subscriptions its not possible to disable the PIN code.This means that every time the unit is restarted, the SIM card wants to have the PIN code before it can register to the GSM network and work properly. However, most of the GSM network operators allow the user to dis-

able the PIN code and the SIM card security is in most cases sufficient when the unit is installed in a restricted and locked area. When using the CSD service its important to confirm with the operator that the service is enabled. Some networks do not support all the data rates supported by the GD-01 US. When using a GSM modem in another GSM operators network its important to check the roaming agreements between the home network operator

(the operator that provided the SIM card) and the other network operator. The coverage area of a specific network may not be sufficient for a reliable connection on a specific place of installation. Several network operators may cover the same area and it could be a good idea to contact other operators to see which network opera-

tor that provide the best GSM signal strength. When using a GSM modem in a fixed location, the network could be equipped with a functionality that de-registers mobile stations that do not originate or receives any connections.When a modem not is registered its not possible to make any outgoing or incoming connections. Some networks de-registers a fixed idle user after 23 weeks and some other network operators does not have this functionality at all. However, this problem can be solved with an AT-command <AT+WRST> that allows the user to configure a timeout period after which the unit will make a reset and re-

register to the network. Please refer to the AT-command listing in the AT-Command guide.The network operator should also be able to provide information whether this function is enabled or not. 6696-2230 19 SIM phonebook Broadcast Control Channel Base Station Identity Code Cell Identity Context Identifier Calling Line Identification Presentation Calling Line Identification Restriction Common PCN Handset Specification Circuit Switched Data Closed User Group 10.
