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

3
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

application.
Keypad, display, microphone, speaker and battery are not part of the modem.
The SIM card is mounted in the modem, accessible by the user under a lid without any tools.
The pins and electrical characteristics or the modem’s various connectors are described in “2. Electrical
Description”
Information about the antenna connector is found in “2.3 Antenna Connector”
1.2 Physical Dimensions and Weight
Overall dimensions: 77 x 67 26 mm
Weight: approx. 100g

2Electrical 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.
This does not apply for the GND on the antenna connector if this coax GND / shield are
connected to your applications ground-plane.
