#87154 - GSM Falcom C55 |
Hello
I already wrote program (Keil C, AT89C52) for sending SMS messages in PDU format. It is tested in Siemens TC35 modul. Now I'm looking for new send/recive device. I had selected Falcom terminal C55. Is there anybody which already use this terminal? In hardware manual is written, that UART levels are 0V(LOW) and 2.65V (HIGH) and on other hand is example to connect terminal to PC with MAX2323 or MAX2328 which has TTL/CMOS otput levels (0V,5V). - Can I connect 8052 Pins (0,5V) directly to the terminal ? Is for comunication to UART on terminal enough to connect RI,TI and GND signals ? Iztok |
