For Vehicles equipped with an airbag
An air bag inflates with great force. DO NOT place objects, including either installed or portable wireless equipment, in the area over the air bag or in the air bag deployment area. If in-vehicle wireless equipment is improperly installed and the air bag inflates, serious injury could result.
Blasting areas
Do not use the unit where blasting is in progress or in “blasting areas”.
Observe restrictions and follow any regulation or rules.
RF energy
The GDW-11 is a low power radio transmitter and receiver. When it is ON, it receives and also sends out radio frequency (RF) signals.
Most modern electronic equipment is shielded from RF signals. However, certain electronic equipment may not be shielded against the RF signals from the wireless unit. All radio-transmitting devices send signals, which may cause interference in different electronic devices. To avoid interference, place the units antenna a sufficiently long distance from other electronics.
Critical applications
Cellular units operate using radio signals and cellular networks cannot be guaranteed to connect in all conditions. Therefore you should never rely solely on a wireless device for essential communications, for example medical emergencies.
Backup copies
Remember to make backup copies of all important data, for example PIN/PUK codes, contents of SIM card etc.
Antenna care
Use only the supplied or an approved replacement antenna. Unauthorized antennas, modifications, or attachments could damage the unit and may violate current regulations.
Do not touch the antenna unnecessarily when the unit is in use. Contact with the antenna affects call quality and may cause the unit to operate at a higher power level than otherwise needed.
Maintenance
No maintenance is required, as long as the unit is used as intended within the specified conditions.

DIP-switch settings
DIP-switches under the lid on top of the unit
!
Before DIP-switch settings:
Warning! Do not open connected unit
Hazardous voltages may occur within this unit when connected to a power supply.
Warning!
Prevent damage to internal electronics from electrostatic discharges (ESD) by discharging your body to a grounding point (e.g. use of wrist strap), before the lid on top of the unit is removed.
To activate DIP-switches Advanced mode needs to be enabled.
NOTE DIP-switch alterations are only effective after a power on or after a software reset command (AT+CFUN=1).
A setting configured by any other method during normal operation, overrides the DIP-switch setting. However, at power up, the DIP-switch settings have precedence over the setting configured by any other method.

Termination recommendations
The RS-422/485 line must be terminated. In the GDW-11 485 / GDW-11 485 EX, the termination is combined with fail-safe functionality. The termination is used to prevent undefined states when the bus is in tri-state condition.
… Using 2-wire RS-485 both ends should be terminated.
… Using 4-wire RS-485 both pairs shall be terminated at both ends.
… Using 4-wire RS-422 it’s only necessary to terminate the receivers.
RS-422/485 connection pins can be differently named. For some equipment brands the T+ corresponds to A, but other brands might use some other naming convention.
If a unit does not work it can help to swap A and B.

Antenna care and placement
!
Warning! Please ensure that power is disconnected from the unit before connecting the antenna.
Since the GDW-11 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 GSM900 and the GSM1800 bands used in the European and most-Asian countries.
Depending on the installation location and surrounding materials, the signal strength reaching the GDW-11 may not be sufficient. The best way to find the optimal position of the antenna is to use the Westermo GD-Tool to measure the “received signal strength”.
The antenna must only be connected locally and not connected to a cable distribution system going outside the building.
24 6615-2203
Windows configuration tool GD-Tool
The GD-Tool is a PC – application program with a graphical interface for easy configuration of the complex functions found in the GDW-11.
Please refer to GD-Tool for a complete description of the functionality of the
Windows program.
Start up guide
Follow the steps below to get the unit up and running in a simple application
Default settings of the serial interface are:
… AT+IPR=9600 9.6 kbit/s
… AT+ICF=3,4
… AT+IFC=0,0
… AT&D0
8 databits, no parity and 1 stop bit.
RTS/CTS flow control disabled
DTR signal is ignored.
Start up steps:
… Insert a valid SIM-card with the appropriate services enabled (e.g CSD data services. GPRS etc)
… Make sure the antenna is connected and placed in the best possible position.
… Power ON the unit and make sure that the PIN code control of the SIM-card is disabled. This can be done either with the help of a mobile phone or with the command AT+CLCK. If the PIN code should be enabled in the application, make sure that the correct PIN code is sent to the modem with the command
AT+CPIN
… Check on the front of the unit that the NET LED is flashing, this means that the unit has a connection to the GSM network and that it has registered on the network.
… Check the received signal quality with the command AT+CSQ. The result value of the first parameter should be between 10 and 31, the value of the second parameter should always be 0.
6615-2203 25
Configuration
The GDW-11 can be configured from the local DTE interface. When the local interface is used the configuration can be made with AT-commands on the serial interface, or with a
PC-based application configuration tool. Factory default settings can also be obtained by using a DIP switch locally.
Standard mode is used for basic GSM modem functionality
Advanced mode adds extended command set and functions. See AT+WOPEN.
