I have a CR1000 datalogger with Fastrack Supreme Wavecom Modem...I want to know the coverage GPRS, and another series of parameters of the modem ... nevertheless I do not manage to accede to the modem in way Hyperterminal....
If I try different speeds (9600-115200 baud)... I do not obtain any response of the modem .... and sometimes it me remains hung and I have to restart.
(I connect using a cable RS232 to sc12 and I use of instruccions to the manual of Campbell to connect the wavecom to the computer).
Thank you.

Please explain what cables/interfaces you are using to connect the Wavecom to the PC. Normally you need what we call a programming cable, which is a 9-way to 15-way cable - this is not the SC12.

Hello Andrew, I connect the wavecom using 9-way to 15-way cable connect directly to wavecom moden and then the SC12 cable to connedt the RS232 computer cable to 9-15 way cable.
I want to send you a photo of the connection, but the Forum does not allow to place photos.
Thank you.
