5. TROUBLESHOOTING: Specific defaults possibly encountered 5.1 The modem does not answer through the serial link A) Is the modem correctly powered on? ❑ If not, the correct power supply is 5 to 32V. TROUBLESHOOTING B) Is the serial cable suitable and adjusted in the modem and PC sockets? ❑ A suitable cable must follow pin assignment described on figure 6. ❑ Check in particular, that Rx et Tx are properly connected.
5.2 The modem always returns «Error» when trying to issue a communication A) Issue AT+CMEE=1 to have extended error code and retry Diagnostic 0 Phone failure 3 Operation not allowed 4 Operation not supported 10 SIM not inserted Hint Call your technical support ➞ Insert the SIM card in the SIM holder of the modem, ➞ If SIM card is inserted, insure that it is clean and properly inserted.
❑ Is the modem receiving an incoming call or already in communication? ➫ With some software versions, you must release any incoming or active call (with ATH) before being able to make an outgoing call. 5.
B) Additional hints ❑ Is the antenna properly connected? Use an antenna with the following features: ➫ Frequency range : dual-band GSM 900/1800 or 900/1900 MHz. ➫ Impedance : 50 Ohms. ➫ Gain (antenna + cable) : 0dBi. ➫ VSWR (antenna + cable) : -10dB. AT+CSQ response (RSSI) Signal quality 11 to 31 ➞ Should be sufficient* 0 to 10 and +99 ➞ Could be insufficient* * based on general observations.
