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

3
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.
This does not apply for the GND on the antenna connector if this coax GND /
shield are connected to your applications ground-plane.

2.5 Serial Data
The modem supports the standard data character format of
Programmable baud rate (300bps to 230,400bps).
Auto-configuration mode with auto-baud (1,200bps to 230,400bps).
Multiplex ability according to GSM 07.10 Multiplexer Protocol.
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.

13
2.8 Mini USB Connector
The modem supports a standard USB 2.0 Full Speed slave interface interface for AT-
commands. The maximum baud rate to communicate with the HT63-E Terminal is up to
12Mbit/s.
Drivers for several operating systems (e.g. Windows Vista, Windows XP or Linux) are available.
Please ask us (su[email protected]).

3 Operation
3.1 Switching ON the modem
There are two ways to switch on the modem, once power is applied:
assert TO_IN to high level for > 1s
activate the RS232 control line DTR
The modem is fully operational after 4 seconds. Logging onto a network may take longer than
this and is outside the control of the modem. The modem can be configured to start up at the
time power is applied by permanently tying power connector signals TO_IN (pin 4) and VCC
(pin 1) together. In this case DTR must be used to switch the modem on again after it has
been switched off or reset, while power is still applied.
DTR must be cycled from low to high.
The TO_IN signal requires a positive “edge” (a sharp” signal transition from low
to high) to turn the modem on. This transition should be a rising signal from 0V
(GND) to VCC, or at least a large fraction of that voltage range, and must be
applied at the same time as VCC or after it. Very slow transitions (significantly
slower than many milliseconds) or very small transitions (e.g. only few volts
instead of 0V to VCC) will not turn on the module (since they are not considered
to be a “positive edge”).
Although this will not be an issue in almost all typical applications of the modem, please
consider following points:
Large capacitors in your power supply which will lead to slow leading and falling edges (issue does
not apply with modern stabilized switching regulator power-adaptors) AND TO_IN tied in parallel
to VCC (instead of separate dedicated digital signal)
Slow analogue signals used to assert TO_IN
TO_IN signal not before VCC
All 3 cases above might prevent the modem from recognizing the power-up signal this is no
failure of the modem itself, the same would apply to almost any electronic device that provides
a separate “power-on” or “reset” signal.
If you are in doubt, please
Use the mains power adapter that is provided by your distributor and is know to work properly with
your modem
Make sure that your signal and system design is according to the above
Consult our support team that will be more than happy to assist you.

3.2 Switching OFF the modem
The only way to switch off the modem is to remove the power source.
3.3 Using low power mode of the modem
Below are some short descriptions on how to enter and exit the low power state of the modem.
3.3.1 Enabling the low power mode:
wait until the GSM module is logged onto the GSM network
send the AT command "AT+CFUN=9"
set the RTS control line from High level to Low level
after about 1-2 minutes, a stable low-power mode should be achieved
3.3.2 Disabling the low power mode by user:
Set the RTS control line from Low to High
Low-power mode should be exited automatically
The RS-232 transceiver is activated immediately
AT channel is available again after a short period of time (37ms)
If applicable send AT command "AT+CFUN=1" to remain in normal mode
3.3.3 Disable the low power modes by incoming GSM activity:
The RTS control line is still at a low level
GSM module is called or receives an SMS
Low-power mode is exited automatically
RS-232 transceiver is activated immediately
AT channel is available again after 37ms
If activated by a call the text "ring" is transmitted via the serial interface
The RTS control line on the DB-9 should be set from Low level to High level
AT communication with the GSM module is now available
If applicable send AT command "AT+CFUN =1" to remain in normal mode
3.4 Operating states / LEDs

Safety and Product Care
Please read the information in this section and the information in “Installation of the
Modem”, before starting your integration work!
4.1 Safety instruction
PLEASE READ THESE SAFETY INSTRUCTIONS AND KEEP A COPY OF THEM.
Always ensure that use of the modem is permitted. The modem may present a hazard if used in
proximity to personal medical electronic devices. As a rule, the modem must not be used in
hospitals, airports or planes.
Never use the modem at a gas station, refuelling point, blasting area or in any other environment
where explosives may be present.
Operating the modem close to other electronic devices, such as antennas, television sets, and
radios may cause electromagnetic interference.
This product is intended to be used with the antenna or other radiating element at least 20cm away
from any part of the human body. In applications where this rule cannot be applied, the
application designer is responsible for providing the SAR measurement test report and
declaration.
You are responsible for observing your country's safety standards, and where applicable, the
relevant wiring rules.
4.2 General precautions
The HT63-E Terminal as a stand alone item is designed for indoor use only. To use outside it
must be integrated into a weatherproof enclosure. Do not exceed the environmental and
electrical limits as specified in “Technical Data”.
Avoid exposing the modem to lighted cigarettes, naked flames or to extreme hot or cold
temperature.
Never try to dismantle the modem yourself. There are no components inside the modem that can
be serviced by the user. If you attempt to dismantle the modem, you may invalidate the warranty.

18
The HT63-E Terminal must not be installed or located where the surface temperature of the plastic
case may exceed 85°C.
All cables connected to the HT63-E Terminal must be secured or clamped, immediately adjacent to
the modem's connectors, to provide strain relief and to avoid transmitting excessive vibration to the
modem in the installation.
Ensure the cables, supplying power, audio headset, and input cable to the HT63-E Terminal, does
not exceed 3 metres.
To protect power supply cables and meet the fire safety requirements when the unit is powered
from a battery or a high current supply, connect a fast 1.25A fuse in line with the positive supply.
Do not connect any incompatible component or product to the HT63-E Terminal.
CEP AG may refuse warranty claims where evidence of product misuse is found.
4.3 SIM card precautions
Before handling the SIM card in your application, ensure that you are not charged with static
electricity. Use proper precautions to avoid electrostatic discharges.
When the SIM card hatch is opened, the SIM card connectors lie exposed under the SIM card
holder.
Caution! Do not touch these connectors! If you do, you may release an electrical discharge
that could damage the modem or the SIM card.
When designing your application, the SIM card’s accessibility should be taken into account. We
always recommend that you have the SIM card protected by a PIN code. This will ensure that
the SIM card cannot be used by an unauthorized person.
4.4 Antenna precautions
If the antenna is to be mounted outside, consider the risk of lightning. Follow the instructions
provided by the antenna manufacturer.
Never connect more than one modem to a single antenna. The modem can be damaged by radio
frequency energy from the transmitter of another modem.
Like any mobile station, the antenna of the modem emits radio frequency energy. To avoid EMI
(electromagnetic interference), you must determine whether the application itself, or equipment in
the application’s proximity, needs further protection against radio emission and the disturbances it
might cause. Protection is secured either by shielding the surrounding electronics or by moving the
antenna away from the electronics and the external signals cable.
The modem and antenna may be damaged if either come into contact with ground potentials other
than the one in your application. Beware, ground potential are not always what they appear to be.

5 Getting started / Installation
This chapter gives you advice and helpful hints on how to integrate the HT63-E Terminal into
your application from a hardware perspective. Please read the information given in “Safety and
Product Care”, page 10 and then read the information in this section before starting your
integration work.
5.1 Where to install the modem
There are several conditions which need to be taken into consideration when designing your
application as they might affect the modem and its function. They are:
5.1.1 Environmental conditions
The modem must be installed so that the environmental conditions stated in the Technical Data
chapter, such as temperature, humidity and vibration are satisfied. Additionally, the electrical
specifications in the Technical Data section must not be exceeded.
5.1.2 GSM Signal strength
The modem has to be placed in a way that ensures sufficient GSM signal strength. To improve
signal strength, the antenna can be moved to another position. Signal strength may depend on
how close the modem is to a radio base station. You must ensure that the location, at which
you intend to use the modem, is within the network coverage area. Degradation in signal
strength can be the result of a disturbance from another source, for example an electronic
device in the immediate vicinity. More information about possible communication disturbances
can be found in section 5.3.5.
When an application is completed, you can verify signal strength by issuing the AT command
AT+CSQ. See “AT + CSQ Signal Strength”.
Tip! Before installing the modem, use an ordinary mobile telephone to check a possible
location for it. In determining the location for the modem and antenna, you should consider
signal strength as well as cable length
5.1.3 Connections of components to HT63 E Terminal
The integrator is responsible for the final integrated system. Incorrectly designed or installed,
external components may cause radiation limits to be exceeded. For instance, improperly made
connections or improperly installed antennas can disturb the network and lead to malfunctions
in the modem or equipment.

20
5.1.4 Network and Subscription
Before your application is used, you must ensure that your chosen network provides the
necessary telecommunication services. Contact your service provider to obtain the necessary
information.
If you intend to use SMS in the application, ensure this is included in your (voice) subscription.
Consider the choice of the supplementary services
5.2 How to install the modem
5.2.1 Power supply
Use a high-quality power supply cable with low resistance. This ensures that the voltages at the
connector pins are within the allowed range, even during the maximum peak current.
When the unit is powered from a battery or a high current supply, connect a fast 1.25A fuse in line
with the positive supply. This protects the power cabling and modem.
5.2.2 Securing the modem
Before securing the modem take into account the amount of additional space required for the
mating connectors and cables that will be used in the application.
Where access is restricted, it may be easier to connect all the cables to the modem prior to securing
it in the application.
Securely attach the HT63-E Terminal modem to the host application using two 3mm diameter pan-
head screws
5.3 Antenna
5.3.1 General
The antenna is the component in your system that maintains the radio link between the
network and the modem. Since the antenna transmits and receives electromagnetic energy, its
efficient function will depend on:
the type of antenna (for example, circular or directional);
the placement of the antenna;
Communication disturbances in the vicinity in which the antenna operates.
In the sections below, issues concerning antenna type, antenna placement, antenna cable, and
possible communication disturbances are addressed. In any event, you should contact your
local antenna manufacturer for additional information concerning antenna type, cables,
connectors, antenna placement, and the surrounding area. You should also determine whether
the antenna needs to be grounded or not. Your local antenna manufacturer might be able to
design a special antenna suitable for the application.
