GSM/GPRS modem Sinaut MD720-3
Sinaut MD720-3 modem is an effective solution for error signaling and monitoring systems building.
Description:
Sinaut MD720-3 - is the GSM/GPRS modem, intended for receiving and transmitting data through GSM standard cellular communication networks. The peculiarities of Sinaut MD720-3 modem are the support of GPRS, class 10 protocol (actively introduced by the mobile network operators) and the RS-232 communication port. The packing arrangement includes all items required for exploitation.
Sinaut MD720-3 has many various functions which are easy to adjust and apply:
- Multichannel GPRS, class 10 (13.4...27 kbps for the connection with the upper control level, 40...54 kbps for the connection with the lower control level);
- Automatic setting and support of interactive connection through GPRS with Internet on the base of IP address;
- Hot swap between GPRS and CSD (modem function);
- CSD and GPRS connection, controlled by AT command system;
- Support of up to 3 telephone numbers for setting of incoming GSM-connections (CLIP function) for connection with teleservice setting;
- Unlimited interaction of client and server even in the protected GPRS networks with private IP addresses of mobile radio network providers.
