Attention!
The metallic housing of the device is connected to the common wire of the control assembly.
The common wire of the coaxial antenna connector is also connected to the housing. The
energy supply and interface circuits are connected to the galvanically isolated common wire of
the discontinuous terminal connector. Power supply can be fed only relating to the terminals
“-“. If the common wire of the energy supply turns to be connected with the Terminal
housing, the system will save its operability, but all the advantages of the galvanic isolation
will fail.

User Manual
As Fig. 3.1 shows, the backup controller receives the following signals:
• Bus-line I2C with TC65 of the GSM module.
On this bus line, in the quality of the Master device (synchronizing signal generator
and bus line initiator) the GSM module always functions, which can transmit the
control commands to the backup controller and receive the information on the system
status. The controller is assigned a 7-bit address on the bus-line (the value is
programmed by the user. On default – 0x7F). It makes it possible to use the bus line
both for communication with the external devices through the interface connector
(cont. 12,13 Fig. 2.5), and for communication with the embedded controller.
By means of I2C commands, the TC65 module is capable of:
o Controlling the SIM card selection;
o Controlling the power supply;
o Changing the temporal and logic parameters for system operation;
o Receiving the information on the system operation mode.
The full list of I2C commands is represented in Table 3.1. To transmit the
commands to the controller from the TC65, it is required (either in the AT
command mode or by Java command call):
o To enter the I2C terminal – AT^SSPI=0000;
o To issue the command in the format <XYYZZBB>, where
• “<” and “>” are mandatory characters signifying START and
STOP of the bus line instance;
• X is any character of the Latin alphabet. It is not transmitted to the
bus line, and it is designed only for indication of the current device
for the TC65;
• YY is a hexadecimal number (0-9,A-F) determining the address of
the device required on the bus-line:
YY7
YY6
YY5
YY4
YY3
YY2
YY1
YY0
Machine address of the required device (on default for the Controller – 0x7F)
0–
“recording”
1–
“reading”
•
ZZ is hexadecimal number (0-9,A-F) determining the code of the
command for the controller;
• BB is a hexadecimal number (0-9,A-F) determining the instruction
operand for the controller (if the command requires it);
The input sequence of characters is not displayed on the screen. It is not
transmitted on the bus line until the input of “>” character. After the
transmission, the Terminal indicates the response o the slave device. If the
transmission has been successful, the module indicates {X+} (X –
indication, “+” – the character signifies “response is received”);
o To transmit the character “#”, which completes the terminal operation.

•
The DTR signal from the interface level converter RS-232 («Serial1», ASC0
TC65).
This signal coming from the external device through the RS-232 is used by the
Terminal to control the GSM module enabling and disabling. The terminal way of
behavior depending on the DTR signal is programmed through the I2C command.
•
The GPIO6 signal from the TC65 module.
It is used by the controller as the SIM card switch alternative signal.
•
SIM card availability signals (SIMPRES1,2) directly from the mounts.
By these signals the controller determines the availability of the mounts during the
SIM card change operations. Besides, during forced extraction of the active
mount, the controller will automatically generate the card unavailability signal
(CCIN) TC65 and attempts to switch the module to the other mount.

Causes hardware blackout TC65 (the
module is disabled, the communication of
the module with the controller is
interrupted. The module can be started only
by the external DTR signal)
The value 0x00 of the operand fully
disables the external digital interface. The
output drivers jump to the status “Off”, and
the inputs TC65 are disconnected from the
terminal inputs (with any values on the
outputs of the GPIO module).
The value 0x01 enables the interface.
After power-on of the terminal and starting
of the GSM module, the interface is enabled
automatically.
The value 0x01 of the operand transmits the
SIM card deactivating signal to the GSM
module. It causes forced disabling of the
module from the GSM network and
deactivation of the SIM interface.
The value 0x00 of the operand transmits the
SIM card availability signal to the module.
The module starts the card reading
operation and registration in the network.
The command sets up the starting mode of
the disabled module by the DTR signal. The
operand value determines the delay in
x100ms (0-25.4s) since the time of the
active DTR signal transmission (>+3V)
until the automatic start of the module. The
value 0xFF disabled the automatic start
mode. The value 0x00 enables the
automatic start at once after the signal
transmission. The interval starts being
counted since the appearance of the active
DTR status (if the signal is not active, the
controller will await its activation and start
the timing). The value is saved in the nonvolatile memory. The value on default is
3.2s. During the timing the indicator
“PWR/STATE” flashes intermittently.

automatic disabling mode. The value 0x00
initiates the automatic disabling at once
after the signal transmission. The value is
saved in the non-volatile memory. The
value on default is 0xFF (disabled). During
the timing the indicator “PWR/STATE”
flashes intermittently.
The command initiates the procedure for
SIM card switching over. The operand
determines the number of the required SIM
mount (0 – the “SIM1” mount, 1 – the
“SIM2” mount). The switching procedure
goes along with the CCIN signal
transmitted to the module, which makes it
possible to disable the SIM interface at the
switching moment, and the automatic start
of registration in the network after the
procedure is completed. If the SIM card
“tray” is unavailable in the mount required
by the command, the switching procedure is
disabled. If the required mount is already
active, the operator is repeatedly registered
in the network. The selected value of the
mount number is saved in the non-volatile
memory of the controller. The last selected
mount is automatically selected upon
power-on. Selection of the mount is
indicated by the corresp. indicators “SIM1”
and “SIM2”.
The command makes it possible to specify
the Controller address on the bus-line I2C.
On this address TC65 will address to the
Controller. It should not be forgotten that
the address byte of the bus-line I2C
contains the address in the higher 7 bits.
The lower bit is used as a reading/recording
marker. If this command transmits the
address 0x7F, the recording commands
must be transmitted to the address 0xFE, the
reading commands – to 0xFF (the
instruction operand shifted to the left by 1
position). It is saved in the non-volatile
memory. The initial value is 0x7F (0xFErecording, 0xFF-reading). The controller
jumps to the new address at once after the

Fig. 3.3. SIM card installation into the terminal
To provide more capabilities for maintenance of GSM connection, the Terminal is equipped
with two SIM-card mounts. Cards of different operators can be installed in these mounts.
The Terminal controller provides switching of the mounts. The switching is made in three
different ways:
Rev. 2-1.0

User Manual
3.2.1. By transmission of the command from TC65 through the bus-line I2C (see
Table 3.1).
This way makes it possible to switch to the particular mount under the number
(SIM1 or SIM2). After the switch, the registration in the network is started
automatically. The value of the current mount is recorded in the non-volatile
memory and selected automatically during power-on. If the “tray” has been
extracted from the required mount, the switching procedure is disabled. (no actions
performed);
3.2.2. By pulsing through the output TC65 GPIO6.
After transmitting of the combination log. “1” – log. “0” to the output GPIO6
(duration of retention of log. 1 - >50us), the Controller starts the SIM card changing
procedure. If the current card has been SIM1, it will switch to SIM2 and vice versa.
In other points, the switching procedure is completely analogous to Clause 5.2.1.
3.2.3. By mechanical extracting of the “tray” of the active SIM mount.
In this case, if the “tray” of the other mount is inserted, the mount changing
operation will be started automatically, similarly with Clause 3.2.1
Important note:
SIM holders transmit into the system the information not about the installed SIM
cards, but about the “trays” clicked up thereon. If an empty tray is clicked in the
mount, the controller will anyway receive the information on the SIM card availability
(see Fig. 11).
The indicators SIM1 and SIM2 flash depending on the selected mount. During the terminal
operation, they flash repeating the signal on the SYNC output of the module TC65 (see the
module documentation) inversely (SYNC=”0” – indicator flashes and vice versa). In the SIM
card change mode both indicators flash simultaneously. In the standby mode the SIM cards
(no “tray” clicked) – indicators flash less frequently and in turn.

Power Supply Control of the Module TC65.
In addition to the regular methods of power supply control of the GSM module TC65
(power-off by the command AT^SMSO, emergency power-off , thermal shutdown etc.), the
Terminal is equipped with some supplementary power supply control functions:
3.3.1. Automatic power-on upon voltage supply.
The module is automatically activated with supply voltage feeding. Exception is
only the case where both SIM mount “trays” are not clicked while the power supply
feeding. In this case the Controller will transmit the initiating command to the
module after clicking of at least one “tray”.
3.3.2. The module starting upon activation of the external DTR signal of the
interface “Serial 1” (ASC0).
Enabling or disabling of this function, as well as the time of retention of the active
DTR status before the start is defined by the Controller setting (I2C command
TC65_DTR_ON see Table 5).
3.3.3. Disabling of the module upon deactivating of the external DTR signal of the
interface “Serial 1” (ASC0).
Enabling or disabling of this function, as well as the time of retention of the passive
DTR status before disconnecting is defined by the Controller setting
(I2Ccommand TC65_DTR_OFF see Table 5).
3.3.4. Disabling of restarting of the module through transmission of I2C
commands. (TC65_off and TC65_reset see Table 3.1 ).

Rev. 2-1.0
The operation of the indicators “SIM1” and “SIM2” has already been described in
Clause 3.2.
The indicator “DBG” is connected in the Terminal to the output GPIO5 of the module
TC65. It flashes upon recording of log. “1” in GPIO5 by means of АТ commands for
GPIO control (or through JAVA) and can be applied by the user for choice.
The indicator “PWR/STATE” is designed for the terminal status indication.
o If it is not flashing – electric power supply is not fed;
o If it is flashing continuously – the module is started and operates normally;
o Frequent flashing – it determines that the Controller is enabling or disabling
the module;
o Rare flashing with predominant off-status - power is supplied, the module is
disabled;
o Rare flashing with predominant on-status – the terminal is conducting the
DTR signal expectation for either enabling or disabling.

4.Supplementary Literature.
Whereas the terminal “TC65Smart” is based upon the GSM module Siemens TC65,
supplementary documentation of the manufacturing company will be needed for operation:
•
TC65 AT Command Set – guidelines on control of the module through the AT
commands.
