1.3.2 Safety Precautions
The following safety precautions must be observed during all phases of the operation, usage,
service or repair of any cellular terminal or mobile incorporating Java Terminals. Manufacturers
of the cellular terminal are advised to convey the following safety information to users and op-
erating personnel and incorporate these guidelines into all manuals supplied with the product.
Failure to comply with these precautions violates safety standards of design, manufacture and
intended use of the product. Gemalto M2M GmbH assumes no liability for customer’s failure to
comply with these precautions.
When in hospitals or other health care facilities, observe the restrictions on the use
of mobiles. Switch off the cellular terminal or mobile if to be instructed to do so by
the guidelines posted in sensitive areas. Medical equipment may be sensitive to RF
energy.
The operation of cardiac pacemakers, other implanted medical equipment and
hearing aids can be affected by interference from cellular terminals or mobiles
placed close to the device. If in doubt about potential danger, contact the physician
or the manufacturer of the device to verify that the equipment is properly shielded.
Pacemaker patients are advised to keep their hand-held mobile away from the
pacemaker, while it is on. This personal subgroup always should check the distance
to the mobile.
Switch off the cellular terminal or mobile before boarding an aircraft. Make sure it
cannot be switched on inadvertently. The operation of wireless appliances in an air-
craft is forbidden to prevent interference with communications systems. Failure to
observe these instructions may lead to the suspension or denial of cellular services
to the offender, legal action, or both.
Check the local and actual laws about these themes.
Do not operate the cellular terminal or mobile in the presence of flammable gases
or fumes. Switch off the cellular terminal when you are near petrol stations, fuel
depots, chemical plants or where blasting operations are in progress. Operation of
any electrical equipment in potentially explosive atmospheres can constitute a
safety hazard.
Your cellular terminal or mobile receives and transmits radio frequency energy while
switched on. Remember that interference can occur if it is used close to TV sets,
radios, computers or inadequately shielded equipment. Follow any special regula-
tions and always switch off the cellular terminal or mobile wherever forbidden, or
when you suspect that it may cause interference or danger.
Road safety comes first! Do not use a hand-held cellular terminal or mobile while
driving a vehicle unless it is securely mounted in a holder for speakerphone opera-
tion. Before making a call with a hand-held terminal or mobile park the vehicle.
Speakerphones must be installed by qualified personnel. Faulty installation or oper-
ation can constitute a safety hazard.
Check the actual and local laws about these themes.

IMPORTANT!
Cellular terminals or mobiles operate using radio signals and cellular networks. In
that case connections cannot be guaranteed at all times under all conditions. There-
fore, you should never rely solely upon any wireless device for essential communi-
cations, for example emergency calls.
Remember, in order to make calls or receive calls the cellular terminal or mobile
must be switched on in a service area with adequate cellular signal strength.
Some networks do not allow for emergency calls if certain network services or
phone features are in use (e.g. lock functions, fixed dialing etc.). You may need to
deactivate those features before you can make an emergency call.
Some networks require a valid SIM card to be properly inserted in the cellular ter-
minal or mobile.
If a power supply unit is used to supply the device it must meet the demands placed
on SELV circuits in accordance with EN60950. The maximum permissible connec-
tion length between the device and the supply source should not exceed 3m.
According to the guidelines for human exposure to radio frequency energy, an
antenna connected to the FME jack of the device should be placed at least 20cm
away from human bodies.

EHS5T‘s RS-485 interface is based on the TIA/EIA-485 standard defining electrical character-
istics of drivers and receivers for use in balanced multidrop communication systems. RS-485
is used in a lot of different fieldbus systems like Profibus, Interbus, Modbus and P-net.
RS-485 uses a shielded twisted pair cable where the shield is used as ground return, and the
inner pairs are used for balanced communication. The two conductors in each pair are called
A and B. RS-485 is usually half-duplex.
Data transmission speed depends on the length of the RS-485 bus cable and may be up to
115kbps.

3.8 Power Supply
35
EHSxT_BGS5T_HID_v02 2014-08-05
Confidential / Preliminary
Page 29 of 70
3.8 Power Supply
The power supply of the Java Terminals has to be a single voltage source of VPLUS=8V…30V
capable of providing a peak current (pulsed 2x577ms at T=4.615ms) of about 1.2A at 8V during
an active transmission. The uplink burst causes strong ripple (drop) on the power lines. The
drop voltage should not exceed 1V, but the absolute minimum voltage during drops must be
>7.6V.
The Java Terminals are protected from supply voltage reversal. An external fast acting fuse
>0.4A with melting integral I2t (0.15 … 0.25)A2s is necessary to use the Java Terminals at a
12V or 24V unlimited power supply system.
The power supply must be compliant with the EN60950 guidelines. A switching regulator reg-
ulates the input voltage for the internal supply.
When power fails for >1ms, Java Terminals reset or switch off. The watchdog can be configured
to restart the Java Terminals. When power fails for >15s the RTC will be reset.
Figure 9: 6-pole Western jack for power supply, ignition, reset, typical connection
Mains adapter: If it fits into the design of your application we recommend the plug-in supply unit
used with the type approved Gemalto M2M reference setup. Ordering information can be found
in Chapter 7. This 12V mains adapter comes with a 6-pole Western plug and provides an inter-
nal connection between IGT_IN pin and PLUS pin for auto ignition (power up).

3.8.1 Turn Java Terminals on
Java Terminals are turned on by plugging an appropriate power supply unit between PLUS and
GND of the 6-pole Western jack.
While the RST_IN pin (pin 3) is not active (voltage <2V) you can start the Java Terminals by
activating the RS-232 DTR line if in POWER DOWN mode.
The IGT_IN signal (pin 4) may be used to switch on Java Terminals if in POWER DOWN mode.
The watchdog can also be configured to turn the Java Terminals on if in POWER DOWN mode.
After startup of the Java Terminals the RS-232 lines are in an undefined state for approx.
900ms. This may cause undefined characters to be transmitted over the RS-232 lines during
this period.
3.8.2 Reset Java Terminals
An easy way to reset the Java Terminals is entering the command AT+CFUN=x,1. For details
on AT+CFUN please see [1].
The watchdog can also be configured to reset the Java Terminals if in POWER DOWN mode.
As an alternative, you can shut down the Java Terminals as described in Section 3.8.3 and then
restart it as described in Section 3.8.1.
3.8.3 Turn Java Terminals off
Normal shutdown:
• To turn off the Java Terminals use the AT^SMSO command, rather than disconnecting the
mains adapter.
This procedure lets the Java Terminals log off from the network and allows the software to
enter a secure state and save data before disconnecting the power supply. After AT^SMSO
has been entered the Java Terminals returns the following result codes:
^SMSO: MS OFF
OK
^SHUTDOWN
The "^SHUTDOWN" result code indicates that the Java Terminals turns off in less than
1 second. After the shutdown procedure is complete the Java Terminals enters the
POWER DOWN mode. The yellow LED stops flashing (see Section 3.13 for a detailed LED
description). The RTC is still fed from the voltage regulator in the power supply ASIC.
Please note that if there is an auto ignition connection between PLUS and IGT_IN the mod-
ule will restart automatically after a normal shutdown.

Page 31 of 70
Emergency restart:
• In the event of software hang-ups etc. the Java Terminals can be restarted by applying a
voltage >8V to the RST_IN pin (pin 3) for more than 10ms.
The RST_IN signal restarts the Java Terminals.
Caution: Use the RST_IN pin only when, due to serious problems, the software is not
responding for more than 5 seconds. Pulling the RST_IN pin causes the loss of all informa-
tion stored in the volatile memory since power is cut off immediately. Therefore, this proce-
dure is intended only for use in case of emergency, e.g. if Java Terminals fails to shut down
properly.
Watchdog shutdown:
• The watchdog can also be configured to turn the Java Terminals off.
When the Java Terminals enter the POWER DOWN mode, e.g. after you have issued the
AT^SMSO command or activated the RST_IN signal, all RS-232 interface lines are active for
a period of 50ms to max. 3.5s. This may cause undefined characters to be transmitted on the
RS-232 lines which can be ignored.
3.8.4 Disconnecting power supply
Before disconnecting the power supply from the PLUS pin, make sure that the Java Terminals
are in a safe condition. The best way is to wait 1s after the "^SHUTDOWN" result code has
been indicated.

3.9 Automatic thermal shutdown
35
EHSxT_BGS5T_HID_v02 2014-08-05
Confidential / Preliminary
Page 32 of 70
3.9 Automatic thermal shutdown
An on-board NTC measures the temperature of the built-in BGS2 module. If over- or undertem-
perature is detected on the module the Java Terminals automatically shut down to avoid ther-
mal damage to the system. Table 17 specifies the ambient temperature threshold for the Java
Terminals.
The automatic shutdown procedure is equivalent to the power-down initiated with the
AT^SMSO command, i.e. Java Terminals log off from the network and the software enters a
secure state avoiding loss of data. In IDLE mode it takes typically one minute to deregister from
the network and to switch off.
Alert messages transmitted before the Java Terminals switch off are implemented as Unsolic-
ited Result codes (URCs). For details see the description of AT^SCTM command provided in
[1].
Thermal shutdown will be deferred if a critical temperature limit is exceeded, while an emer-
gency call or a call to a predefined phone number is in progress, or during a two minute guard
period after power up. See [1] for details.
The watchdog can be configured to restart the Java Terminals after a defined period.
3.10 Hardware Watchdog
The Java Terminals feature a programmable hardware watchdog that permanently monitors
the terminals‘ hardware and can be configured to react to various hardware states. The watch-
dog may for example be configured to periodically restart the terminal, independant of its cur-
rent operating state. Figure 4 shows how the watchdog is integrated into the Java Terminals.
Please refer to Chapter 8 for details on how to control and configure the hardware watchdog.
3.11 RTC
The internal Real Time Clock (RTC) of the Java Terminals retains the time and date and han-
dles the alarm (reminder) function. The AT+CCLK command serves to set the time and date,
and AT+CALA specifies a reminder message. See [1] for details.
A dedicated voltage regulator backs up the RTC even in Power Down mode and enables Java
Terminals to keep track of time and date.
However, please note that the Alarm mode described in [1], Section AT+CALA, is not intended
for the Java Terminals. The AT+CALA command can only be used to set a reminder message,
but not to configure the mobile to wake up from POWER DOWN mode into Alarm mode. There-
fore, after setting a timer with AT+CALA be sure not to shut down the Java Terminals by
AT^SMSO or RST_IN signal.

2. The card holder is a five wire interface according to GSM 11.11. A sixth pin has been added
to detect whether or not a SIM card is inserted.
Figure 10: SIM interface
The SIM - with the circuit side facing upwards - is inserted by gently pushing it into the SIM card
holder until it snaps hold. It is now protected from accidental removal. The SIM can be removed
from the card holder by using a flat object such as a screwdriver to carefully press the inserted
SIM until it snaps out again.
All signals of the SIM interface are protected from electrostatic discharge with spark gaps to
GND and clamp diodes to 1.8V resp. 2.9V and GND.
Removing and inserting the SIM card during operation requires the software to be reinitialized.
Therefore, after reinserting the SIM card it is necessary to restart Java Terminals.
Note: No guarantee can be given, nor any liability accepted, if loss of data is encountered after
removing the SIM card during operation. Also, no guarantee can be given for properly initializ-
ing any SIM card that the user inserts after having removed a SIM card during operation. In this
case, the application must restart the Java Terminals.

3.13 Status LEDs
Java Terminals have two LEDs indicating its operating states through the semitransparent cas-
ing:
• A green LED indicates whether the Java Terminals are ready to operate.
• A yellow LED indicates the network registration state of the Java Terminals.
Figure 11: Status LED
The yellow LED is driven by a line of the integrated module that can be configured by using the
AT^SLED command to either light permanently or to flash. For details on the AT command

3.14 RF Antenna Interface
An external RF antenna is connected via the Java Terminals’s female SMA connector that is
also the antenna reference point (ARP).
Figure 12: Antenna connector
The system impedance is 50. In any case, for good RF performance, the return loss of the
customer application’s antenna should be better than 10dB (VSWR < 2). Java Terminals with-
stand a total mismatch at this connector when transmitting with power control level for maxi-
mum RF power.
Inside the Java module an inductor to ground provides additional ESD protection to the anten-
na connector. To protect the inductor from damage no DC voltage must be applied to the an-
tenna circuit.
For the application it is recommended to use an antenna with an SMA (male) connector:
Please note that the terminal should be installed and operated with a minimum distance of
20cm between the antenna connected to the terminal and any human bodies. Also, the trans-
mitter must not be co-located or operating in conjunction with any other antenna or transmitter.
The allowed maximum antenna gain (including cable loss) for stand-alone situation is given be-
low in Table 14.

There are a number of ways to mount the Java Terminals:
• Java Terminals can be attached to a rail installation or other surface using the two provided
screw holes.
• Java Terminals can be fastened to a rack or holding using the two provided fixtures for
cable straps.
• Java Terminals can be slid onto a specific DIN rail made according to DIN EN 60715 - C
section, C30 format. A catch at the terminal’s bottom side will have to be removed to slide
multiple terminals onto a single rail.
• Using a BOPLA TSH 35-2 universal DIN rail holder the Java Terminals can be fitted onto
another special type of DIN rail made according to DIN EN 60715 - Top hat section, 35mm
(e.g., Wago 210-113 steel carrier rail).
The following figure shows the various possibilities provided to mount the Java Terminals.

8 Appendix A: (Hardware) Watchdog
The watchdog is part of the Java Terminals and connected to the Java module itself (see also
Figure 4). It can be used to
• Safely reset the module in certain conditions
• Restart the module when it has turned off
• Configure GPIOs and DSR0/ADC1_IN available at the Weidmueller connector
The complete watchdog functionality can be configured via the serial interface ASC0 (for de-
tails see Section 8.3). Some configuration commands can also be specified via I2C interface
(for details see Section 8.4). Figure 17 shows how the watchdog may be accessed.
Figure 17: Hardware watchdog
8.1 Reset Conditions
The watchdog implements three conditions, under which a reset of the module is automatically
performed:
• Repetitive: A module reset is performed frequently and repetitive. This reset condition can
be used to force the module to reconnect to the mobile network once in a while. Typical fre-
quencies are 24 hours or more. This feature can be configured via the RST_REP timeout.
• UART activity: The watchdog can be used to reset the module, when no activity from the
module on the UART interface is recognized for a specified amount of time. To prevent the
reset, the module has to be active frequently on the UART interface. This reset condition
can be configured via the RST_UART timeout, it is deactivated when timeout parameter = 0.
• GPIO activity: The watchdog can be used to reset the module, when no activity on the des-
ignated GPIO signal is recognized for a specified amount of time. To prevent the reset, the
module has to be active frequently by toggling this GPIO signal. This reset condition can be
configured via the RST_GPIO timeout, it is deactivated when timeout parameter = 0.
When the watchdog is enabled, it will observe the activities on the UART and GPIO interfaces,
depending on timeout parameter setting and perform frequent resets, if it is configured to do so.

Page 55 of 70
8.1.1 Reset stages
There are up to three possible escalation stages during a module reset:
• First stage (regular fast shutdown): The watchdog shuts down the module via an internal
fast shutdown signal. The fast shutdown procedure will then still finish any data activities on
the Java module's flash file system, thus ensuring data integrity, but will no longer deregis-
ter gracefully from the network, thus saving the time required for network deregistration.
Afterwards, i.e. after an internal V180 signal has gone low, the module is regularly re-
started.
• Second stage (emergency restart): The watchdog resets the module via an internal
EMERG_RST signal. The emergency restart procedure causes the loss of all information
stored in the Java module‘s volatile memory.
• Third stage (power off): The watchdog switches the module off.
After the first and second stage the watchdog waits for up to three seconds for the internal V180
signal to go LOW. If the V180 signal does not change, the watchdog escalates to the next
stage, until it finally ends up switching off the module. The watchdog can be configured to au-
tomatically switch on resp. power up the module after a shutdown (always-on mode).
8.1.2 Reset Delay
The watchdog implements a protection mechanism to prevent too frequent module resets.
When the delayed reset mechanism is enabled, the watchdog will start its activity only after the
specified amount of time, MIN_START_TIME. A reasonable value for this timeout is 30 min-
utes. After the watchdog startup, after a module reset and also after enabling the watchdog, no
reset of the module is performed before the timeout of MIN_START_TIME.
When the watchdog is enabled, resets can be prevented once for a certain amount of time. This
timeout, TRG_DEL, can be configured via the I2C interface. It can be particularly useful when
a software update shall be performed. Using the TRG_DEL timeout will prevent the watchdog
from resetting the module during the running TRG_DEL timeout, so that the update can be per-
formed safely. An upcoming reset event will be shifted and catch up after the TRG_DEL time-
out.
8.2 Restart Conditions
When the watchdog is enabled, it will observe the modules on/off state. When it is configured
to keep the module "always on", it will restart the module after the specified amount of time after
it has discovered that the module has turned off. This important feature is useful in rough envi-
ronments with often power losses and out-of-temperature conditions where it secures a safe
module operation. The timeout condition for the restart feature is called ALWAYS_ON.

Page 56 of 70
8.3 Configuration via ASC0 Interface
The complete hardware watchdog functionality can be configured via the serial interface ASC0
as described in this section.
The watchdog listens on the module's TXD0 line exclusively at the low baudrate 1200bps, and
gives no feedback. This means that if using the watchdog this low baud rate is reserved and
should not be configured for the module‘s asynchronous serial interface ASC0. The TXD0 line
can be accessed either via RS-232 interface or via RS-485 interface (in conjunction with an
RS232-to-RS485 adapter).
So, to control and configure the watchdog, a terminal program MUST be set to 1200bps, before
a command (see Section 8.3.1) can be sent to the watchdog. Once completed, the terminal
program should be changed to higher baud rates again to enable proper communication with
the module.
Please note that some configuration commands can also be configured via I2C interface (see
Section 8.4 for details).
8.3.1 Command Specification
The general watchdog command syntax is as follows:
WD=<command>,<argument>,<checksum><NL>
Where
• <command> specifies the command name
• <argument> gives the numeric argument
• <checksum> is the sum of the digits of the argument. (e.g. the argument 124 produces a
checksum 7, because 1+2+4=7).
Whenever a non-volatile command is executed, it is saved in the watchdog's flash memory. At
watchdog start, the last state is loaded from flash memory.
If a config command was successfully executed by the watchdog, the green ON led flashes two
times. The watchdog commands are implemented as text commands. In case a command error
occours - e.g., a checksum failure - the green ON led flashes 4 times.

Note: Changing the watchdog configuration using any of the following commands disables the
watchdog: Repetitive module reset, UART reset, GPIO reset, Restart delay and Always on.
With these commands the new configuration setting becomes effective only after the hardware
watchdog is enabled again.
8.3.1.1 Watchdog On/Off
This command is used to enable or disable the watchdog function. When disabled, all timers
are stopped and the watchdog doesn't perform a module reset. When enabled, all configured
timers start after a delay time of MIN_START_TIME. If MIN_START_TIME=0, all reset timers
start immediately. Also, when the watchdog is enabled and ALWAYS_ON>0, the watchdog ob-
serves the modules on/off state, and starts the module in case it detects that the module is off.

8.3.1.2 Test Mode
This commands configures the watchdog‘s test mode. In test mode the watchdog operates nor-
mally, but does not actually perform a module reset. Instead, it signals the (simulated) reset via
the LED by flashing the green ON LED two times to visualize the watchdog trigger. Entering
the test mode disables the actual watchdog functionality.
8.3.1.3 Repetitive Module Reset
This command configures a repetitive module resets, if the watchdog is enabled. The param-
eter sets the RST_REP timeout value. If the watchdog is enabled, an unconditional module re-
set every RST_REP milliseconds is performed.
Changing this configuration disables the watchdog. The feature becomes active, if the watch-
dog is enabled again, and after the MIN_START_TIME has passed.
For normal operation, this value should be set to a value greater than 30 minutes.

8.3.1.4 UART Reset
This command configures a module reset, if no UART activity from the module was observed
for the specified amount of time - RST_UART. The module has to be active on the RXD0 signal
within the specified time period; otherwise the watchdog will reset the module.
Changing this configuration disables the watchdog. The feature becomes active, if the watch-
dog is enabled again, and after the MIN_START_TIME has passed.
For normal operation, this value should be set to a value greater than 10 minutes (600000).
8.3.1.5 GPIO Reset
This command configures a module reset, if no activity from the module was observed on the
internal signal WD_RETRIG for the specified amount of time. The module has to be active on
the WD_RETRIG signal by toggling the GPIO22 module output within the specified time period.
Otherwise the watchdog will reset the module. If enabled, each GPIO22 toggling resets the tim-
er to its configured value.
Changing this configuration disables the watchdog. The feature becomes active, if the watch-
dog is enabled again, and after the MIN_START_TIME has passed.
For normal operation, this value should be set to a value greater than 10 minutes (600000).

8.3.1.6 Restart Delay
This command configures the MIN_START_TIME timeout value. By setting the
MIN_START_TIME, the watchdog no longer performs a module reset for the given amount of
time, after module startup. Whenever the module has been reset and restarted, as well as after
the watchdog has been enabled, the watchdog will wait for MIN_START_TIME before perform-
ing any (further) resets. The watchdog‘s reset timer only starts after the MIN_START_TIME has
expired.
Changing this configuration disables the watchdog. The feature becomes active, if the watch-
dog is enabled again.
It is strongly recommended to set this value to a time period of more than 30 minutes for normal
operation. During development it may be set to values of less than 30 minutes, but should al-
ways be greater than the time the module needs for a complete start up including Java. Also,
a module firmware or userware update right after startup should be taken into account which
may take up to 15 min.
Command MIN_START_TIME
Parameter <timeout>
Type Milliseconds
Range 0 .. 232-1
Default 18000000ms (30 minutes)

8.3.1.7 Always On
This command configures the on/off-state observation of the module by specifying a timeout
value for ALWAYS_ON. If enabled, the watchdog observes the module‘s internal V180 signal.
If the watchdog detects that the module is OFF, it will restart the module after the timeout of
ALWAYS_ON milliseconds.
Changing this configuration disables the watchdog. The feature becomes active, If the watch-
dog is enabled.
It is strongly recommended to set this value to a time period of more than 1 minute for normal
operation to avoid oscillation in e.g. out-of-temperature events. In case of over/under temper-
ature shut down it can be expected that the temperature does not change significantly within a
minute. During development the timeout may be set to a period of less than 1 minute.
8.3.1.8 Load Default Values
This command loads the default configuration values. This disables the watchdog. If the watch-
dog is enabled, the reset timeout values, the MIN_START_TIME timeout and the
ALWAYS_ON timeout become active. Other configuration values become active immediately.
The loaded default values are also persistent, i.e. written to the flash memory.
Command ALWAYS_ON

8.3.1.9 Change the Watchdog‘s I2C Address
The watchdog‘s I2C slave address can be changed to any 7-bit address. This may become nec-
essary to avoid address conflicts on the I2C bus, if used in an environment, where the default
I2C address "0x6A" is already in use by other slave devices connected to the Java Terminal.

8.3.1.10 Set GPIO Direction
This command configures the input/output direction of level-shifters to the module‘s externally
available GPIO pins. The argument is a 10-bit number, representing the 10 adjustable direc-
tions of the GPIO level-shifters. A set bit (value 1) sets the respective level-shifter to the output
direction. A cleared bit changes the respective level-shifter to input direction. The following ta-
ble describes the connection between the 10-bit argument number, the modules GPIO pins,
and the Java Terminals Weidmueller connectors 8-pin and 12-pin:
Changing the directions of the level-shifters must be executed with great care. They may only
be set in accordance with the modules GPIO‘s input/output configuration. Special care must be
taken that no outputs are cross-connected during the switching phase.
Configuring a Java terminal output, the level shifter output must be set first, followed by the
module output configuration.
Configuring a Java terminal input, the module input must be set first, followed by the level shift-
er input.
Please note that the GPIO direction can also be configured via I2C interface. It is recommended
to use the I2C interface to configure the GPIO direction.

This command configures the the ADC/DSR0/SPI_CLK signal on the Weidmueller connector
to be either an analog input line (ADC) or a digital output line (DSR0/SPI_CLK). If configured
as analog input, the signal is connected to the Java module‘s ADC1_IN line. If configured as
digital output, the signal is connected to the Java module‘s DSR0/SPI_CLK line that can be
configured to be either DSR0 or SPI_CLK (SPI_CLK not available for BGS5T USB).

8.4 Configuration via I2C Interface
While the complete watchdog functionality may be configured via ASC0 interface (for details
see Section 8.3) some of the configuration commands can also be configured during runtime
via I2C interface as described in this section.
The I2C interface is accessible either via the external Weidmueller connector - I2CDAT and
I2CCLK, or via the Java module‘s AT command interface (e.g., ASC0), or through a Java MID-
let during runtime.
The I2C interface implements the write and the read protocol as described in Section 8.4.1. The
7-bit device address is 0x6A (binary: 1101010). The default address can be changed by con-
figuration command (see Section 8.3.1.9).

8.4.1.3 I2C Protocol Overview
In write mode (i.e., slave address “0xD4“), one address byte and one data byte is sent to the
Java Terminal/Watchdog. The address byte specifies a register to write the data byte to. The
data byte value is only written, if it is valid, i.e., in the specified range. After a write attempt, the
status code of the operation is saved and the read address register (RAR) is automatically set
to the status register address (SR). A subsequent read command from the status register (SR)
will then return the latest status code (see Table 26). Only when the address byte is the RAR,
i.e. another register is selected to be read, the RAR is not automatically set to the SR register.
See Section 8.4.1.4 for sample watchdog configurations via I2C.
In read mode, one data byte can be read from the Java Terminal/Watchdog. Attempts to read
more bytes will result in undefined values being returned by the device. The device will always
return the value that is addressed by the RAR. To read a specific register, a write command
with RAR as the address byte and the register to be read as the data byte has to be issued first.
The next read will then return the value at this address. Note that there are only a few registers
that can be read (see register table - Table 25). When the RAR is written with a non-read ad-
dress, the RAR is set to the SR, and the status code ILLEGAL_ARGUMENT is saved. Note
also that a consecutive read is not valid, as the return value will be ILLEGAL_ARGUMENT, but
the caller cannot determine whether the result is the value at the faulty address or an error sta-
tus code. See Section 8.4.1.4 for sample watchdog configurations via I2C.

Examples
The following two samples show how the watchdog can be configured via the I2C interface, us-
ing the AT^SSPI command (at RS-232/ASC0) to transfer the I2C user data. Please refer to [1]
for more information on the AT command AT^SSPI and on how to configure and control the
data transfer over the I2C interface.
The above Table 25 specifies the address register that can be used in I2C configuration com-
mands.
The first example sets GPIO12 to “output“. It therefore configures a write register marked as
“W“ in Table 25.

WRITE command enclosed by <>: “a“ is a command ID to better identify and match
acknowledgments, “D4“ indicates the slave address (write mode), “14“ specifies
the address register GPIO12, and “01“ sets the data byte (i.e., line is “output“).
Note: The data byte value is only written if valid, i.e., if in the specified range. After
a WRITE command, the status code of the operation is saved to the status register
(SR) and a subsequent READ command from the status register will then return
the latest status code as listed in Table 26.
Acknowledgement enclosed in curly brackets of a successful data transmission.
READ command enclosed by <>: “b“ is a command ID to better identify and match
acknowledgements, “D5“ indicates the slave address (read mode), “00“ specifies
the address register SR, and “01“ sets the data length to be read. Note: The READ
command can only be called in conjunction with the SR address “00“ and the data
length of one byte “01“.
Acknowledgement enclosed in curly brackets of a successful data transmission,
together with the response code “00“ indicating that the command was successful-
ly executed.

The second example listed below reads out the firmware version, it therefore uses a read reg-
ister marked as “R“ in Table 25.
However, except for the status address register (SR) no information can be directly retrived
from an address register itself, but only indirectly by means of a so-called read-address-register
(RAR). An initial WRITE command has to link the register to be read to the RAR first. Now the
RAR is linked to the register to be read, and the content of this register can be read from the SR.

WRITE command enclosed by <>: “a“ is a command ID to better identify and match
acknowledgments, “D4“ indicates the slave address (write mode), “FF“ specifies
the read address register RAR, and “FD“ sets the data byte to the watchdogs firm-
ware version register VER (i.e., RAR and VER are linked by this command). Note:
The data byte value is only written if valid, i.e., if in the specified range. After a
WRITE command, the status code of the operation, in this case, i.e., where the
register address is the RAR, the content of the register given as data byte is saved
to the status register (SR) and a subsequent READ command from the status reg-
ister will then return the register value, i.e., the firmware version.

length of one byte “01“.
