MTX M2M® by MATRIX ELECTRONICA S.L.U
Features (when connected to ASC0)
• Includes the data lines TD0 and RD0, the status lines RTS0 and CTS0 and also the modem
control lines DTR0, DSR0 and DCD0.
• This port is primarily designed for controlling voice calls, transferring CSD, fax and GPRS data
and for controlling the GSM engine with AT commands.
• Full Multiplex capability allows the interface to be partitioned into three virtual channels, but
with CSD and fax services only available on the first logical channel.
• The DTR0 signal will only be polled once per second from the internal firmware of MTX-IoT.
• The default configuration is 8 data bits, no parity and 1 stop bit. The setting can be changed
using the AT command AT+ICF and, if required, AT^STPB.
• Can be operated at fixed bit rates from 1200bps to 921600bps.
• Autobauding supports bit rates from 1.2kbps to 460.8kbps.
• The default serial speed for MTX-IoT is 115200bps.

• Configured for 8 data bits, no parity and 1 or 2 stop bits.
• Can be operated at fixed bit rates from 1200 bps to 921600 bps. Autobauding is not supported
