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 ❏ The power supply must be able to deliver current peaks up to 1.8A@5V (see chapter 2.3.5 for further details). B) TROUBLESHOOTING ❏ ❏ Is the serial cable suitable and adjusted in the modem and PC sockets? A suitable cable must follow pin assignment described on figure 6.
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 Hint Call your technical support 3 Operation not allowed 4 Operation not supported 10 SIM not inserted → Insert the SIM card in the SIM holder of the modem, → If SIM card is inserted, insure that it is clean and properly inserted.
❏ 5.3 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.
B) Additional hints ❏ Is the antenna properly connected? Use an antenna with the following features: ➫ Frequency range : dual-band GSM 900/1800 MHz. ➫ Impedance : 50 Ohms. ➫ Gain (antenna + cable) : 0dBi. ➫ VSWR (antenna + cable) : -10dB. Is the received signal strong enough? ➫ With the AT-Command AT+CSQ check that the received signal (1st parameter of the response) is strong enough to be able to establish a call.
