TC65 Terminal_HD_V02.000b
Implementation
•
8-wire modem interface with status and control lines,
unbalanced, asynchronous
•
Fixed bit rates: 300 bps to 460,800 bps
•
Autobauding: 1,200 bps to 460,800 bps
•
Supports RTS0/CTS0 hardware handshake and software
XON/XOFF flow control.
•
Multiplex ability according to GSM 07.10 Multiplexer Protocol.
I 2 C bus for transmission rates up to 400kbps.
Programmable with AT^SSPI command.
Alternatively all pins of the I²C interface are configurable as SPI.
Serial Peripheral Interface for transmission rates up to 6.5 Mbps.
Programmable with AT^SSPI command.
The I²C interface is not available by using the SPI interface.
Analog (Microphone, Earpiece)
Supported SIM cards: 3V, 1.8V
Connected via antenna SMA connector
Switch on via On/Off push button, ONOFF line on IO interface
connector,
DTR line at RS232 interface or IGT_IN line at power connector
(available with recommended power supply)
•
Normal switch-off by AT^SMSO or On/Off push button
•
Emergency switch-off via EMERGOFF line at power
connector
•
Automatic switch-off in case of critical temperature and
voltage conditions
Orderly shutdown and reset by AT command
Timer functions via AT commands
10 I/O pins of the application interface are programmable as
GPIO. Programming is done via AT commands. Alternatively,
GPIO pin 10 is configurable as pulse counter.
Pulse counter for measuring pulse rates from 0 to 1000
pulses/sec.
If the pulse counter is active the GPIO pin 10 is not available.
Analog-to-Digital Converter with two balanced analog inputs for
measuring external voltages.
