Therefore only touch the CT63 Terminal on the housing or
connectors and avoid touching the components on the board.
When using products which are exposed to electric voltage the valid
regulations have to be observed.

Important information
This technical description contains important information for start up and use of the CT63 Terminal.
Read it carefully before you start working with the CT63 Terminal.
The warranty will be void should damage occur due to non-compliance with these instructions for use.
We cannot accept any responsibility for consequential loss.
We cannot be held responsible for material loss or personal injury that is due to incompetent use or
non-compliance with the safety instructions. The warranty will be void in such circumstances.
The CT63 Terminal contains highly integrated components which can be damaged by electrostatic
discharge if the user would open the housing.
CEP preserves the right to change the included information without notice and doesn‟t take
responsibility for errors in the document and/or missing information.
Safety Instructions
Before opening of a device always pull the mains adapter or make sure that the device is
disconnected from the power supply.
You should only use tools on components, modules or devices if they are disconnected from the
power supply and the electric charge, which may still be stored in some components, inside the device
has been discharged.
All cables and wires which are energized and connected to the device, the module or components
have to be checked regularly for any damage of the isolation shield or fractures of the cables. If the
supply cables are visibly damaged the device has to be taken out of operation immediately until the
faulty cable has been exchanged.
When using components or modules it is necessary to strictly observe the specification given in the
corresponding description of these components. If a description for a private end-customer not clearly
states which electric data is valid for a component or a module, how to wire the device, which external
components or additional devices can be connected or which parameters these components are
allowed to have, a specialist must be contacted.
Before putting a device into operation, it has to be clarified, whether this device or module is meant for
the field of application. In case of doubt ask specialists or the manufacturer of the device.
Please note that we are not responsible for any errors in usage or connection. Therefore we cannot
accept any responsibility for consequential loss.
Devices which operate with >35 Volt have to be connected by a specialist. Before putting the device
into operation it should be checked that there is no current leakage on the housing.
In case those measurements with the opened housing are necessary, an isolating-transformer has to
be integrated for safety reasons. Alternatively the voltage can be supplied by an appropriate power
supply which complies with the safety regulations. All wiring work has to be done in a voltage free
state only.

2 Electrical Description
The modem uses the following standard connectors:
RJ11 6-way (power connector)
Mini USB (USB 2.0)
SIM card reader
FME male coaxial jack (antenna connector)
Sub-D female socket, 9 pin (RS232 serial port)
2.1 Power Connector
An RJ11 6-way connector, as shown and described below, serves as a means of
supplying and controlling DC power to the modem. It is necessary to connect an
external power supply, since the available power on the USB port is not sufficient to
run the modem.
The supply voltage, VCC, required by the modem is 5V - 32V DC. Application of the
supply voltage does not switch the modem on. To do so an additional active-high
control signal, TO_IN, must be applied for > 1 second.
Please see chapter “3.1 Switching ON the modem” for further important details about
TO_IN and power supply requirements, especially if TO_IN is applied in parallel to
VCC.
VCC and GND are reverse-polarity and over-voltage protected.

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:
The modem supports the standard data character format of

2.6 Serial Data Signals
Serial Data From Modem (RD)
RD is an output signal that the modem uses to send data to the application.
Serial Data To Modem (TD)
TD is an input signal, used by the application to send data to the modem.
2.7 Control Signals – RTS, CTS, DTR, DSR, DCD, RI
Request to Send (RTS)
RTS is used to condition the DCE for data transmission. The default level is high by
internal pull up. The exact behaviour of RTS is defined by an AT command. Software
or Hardware control can be selected. Hardware flow is the default control. The
application must pull RTS low to communicate with the modem. The modem will
respond by asserting CTS low, indicating it is ready for communication.
Clear To Send (CTS)
CTS indicate that the DCE is ready to transmit data. The default level is high. You
can define the exact behaviour of CTS through an AT command, and can select
software or hardware flow control.
Data Terminal Ready (DTR)
DTR indicates that the DTE is ready to transmit and receive data. It also acts as
hardware „hang-up‟, terminating calls when switched high. The signal is active low.
You can define the exact behaviour of DTR with an AT command. The DTR line can
also be used to switch on the modem when activated for 0.2 seconds. The DTR line
must be deactivated prior to switching off the modem to ensure it switches off
(powers down) correctly.
Data Set Ready (DSR)
An active DSR signal is sent from the modem to the application (DTE) to confirm that
a communications path has been established. DSR has two modes of operation,
settable using the AT command AT&S.
Data Carrier Detect (DCD)
DCD indicates that the DCE is receiving a valid carrier (data signal) when low. You
can define the exact behaviour of DCD with an AT command.
Ring Indicator (RI)
RI indicates that a ringing signal is being received by the DCE when low. You can
define the exact behaviour for RI with an AT command.
