SAFETY PRECUTIONS

z The modem generates radio frequency (RF) power. When using the modem care must be taken on safety issues related to RF interference as well as regulations of RF equipment.

z Do not use your phone in aircraft, hospitals, petrol stations or in places where using GSM products is prohibited.

z Be sure that the modem will not be interfering with nearby equipment. For example: pacemakers or medical equipment. The antenna of the modem should be away from computers, office equipment, home appliance, etc.

z An external antenna must be connected to the modem for proper operation. Only uses approved antenna with the modem. Please contact authorized dealer on finding an approved antenna.

z Always keep the antenna with minimum safety distance of 26.6 cm or more from human body. Do not put the antenna inside metallic box, containers, etc.

Using the modem in vehicle z Check for any regulation or law authorizing the use of GSM in vehicle in your country before installing the modem z Install the modem by qualified personnel. Consult your vehicle dealer for any possible interference of electronic parts by the modem.

z The modem should be connected to the vehicle’s supply system by using a fuse-protected terminal in the vehicle’s fuse box z Be careful when the modem is powered by the vehicle’s main battery. The battery may be drained after extended period.

Protecting your modem z To ensure error-free usage, please install and operate your modem with care. Do remember the following: z Do not expose the modem to extreme conditions such as high humidity/rain, high temperatures, direct sunlight, caustic/harsh chemicals, dust, or water.

z Do not try to disassemble or modify the modem. There is no user serviceable part inside and the warranty would be void.

z Do not drop, hit or shake the modem. Do not use the modem under extreme vibrating condition.

z Do not pull the antenna or power supply cable. Attach/ detach by holding the connector.

z Connect the modem only according to the instruction manual. Failure to do it will void the warranty.

z In case of problem, please contact authorized dealer.

5.2 Input / Output port

This port can be configured as either an input one or an output one.

To configure it as an input port, first issue AT+WIOW=2, 0 to disable the output port. Use

AT+WIOR=3(Maestro 100) or AT+WIOR=1(Maestro 20) to read the status of this input port. Response

+WIOR: 0 represent Logic HIGH (>3V); Response +WIOR: 1 represent Logic LOW (<0.5V) To use it as an output port, issue AT+WIOW=2,1 will turn it on and it will drain current to ground. The current is recommended not to exceed 10 mA. Issue AT+WIOW=2,0 will turn it off.

5.3 RS232 AUTO-ONLINE mode (power saving)

When being in the AUTO-ONLINE, the RS232 transceiver will shutdown most of its hardware to save power if it does not detect a valid input for more than 100uS. The RS232 transceiver will wake up when valid input is detected again.

By default, the RS232 transceiver is put in AUTO-ONLINE. This mode can be turned off by issuing

AT+WIOW=4,1.

CHAPTER 6

TROUBLESHOOTING

6.1 The modem’s LED does not light :

Check if the modem has connected to a 5-32V power supply properly

Check if the power connector is properly inserted

Check the fuse on the power cord

6.2 The modem’s LED lights but does not blink long time after power up

Check if a valid SIM card has been inserted properly

Check if the SIM card has been locked (refer to AT+CPIN command in AT command guide)

Check if the external has been connected properly to the modem

Check if the network coverage is available.

6.3 The modem does not response to the terminal program

Check if the RS-232 cable has been connected properly

Check if your program has proper setting. Factory setting of the modem is:

9600bps

8 data bits no parity bit

1 stop bit

6.4 No voice could be heard for the modem’s speaker output when a call is answered

Make sure a voice call has been made (refer to AT command guide)

Enter the AT+SPEAKER=1 command
