2.3 SIM card reader
The CT63 Terminal is fitted with a SIM card reader designed for 1.8V and for 3V SIM
cards. It is the flip-up type which is lockable in the horizontal position and is accessed
through a removable panel.
2.4 RS232 Serial Port
The modem supports a standard RS232 serial interface via its 9 pin Sub-D connector,
shown below. In line with serial communication terminology the CT63 Terminal
should be considered as the data circuit-terminating equipment (DCE) and the
external application or computer as the data terminating equipment (DTE). The
maximum baud rate to communicate with the CT63Terminal is 230400 kbit/s.
The electrical characteristics of the serial port signals are shown below:
