In this mode the probe can automatically detect
IEC 62056-21 Mode C (formerly known as IEC1107)
protocol and make necessary baud change over
automatically.
This mode is designed so that any software that can
read IEC 62056-21 meters with cable version of optical
probe can instantly use Bluetooth version of probe.After
pairing the probe the already available software can
instantly use this mode to read meters such as Elster,
EMH, L&Gyr etc.
MODE 2: 300-7E1 IEC START AND
CHANGE TO DLMS/COSEM
In this mode the probe can automatically detect
IEC 62056-21 Mode C (formerly known as IEC1107)
opening on DLMS / COSEM protocol and make necessary
baud and data type change over automatically.
This mode is designed so that any software that can
read DLMS / COSEM meters with IEC opening mode
with cable version of optical probe can instantly use
Bluetooth version of probe. After pairing the probe the
already available software can instantly use this mode
to read meters such as Itron, L&Gyr etc.

MODE 3: FIXED 9600-8N1
COMMUNICATION
This is xed speed and data type communication mode.
This can be used in IEC870-5-102 standard or in any
standard that is necessary to communicate in this data
type and baud rate.
MODE 4: CUSTOM COMMAND MODE
In this mode the device will work transparently and
communication can be controlled by special commands.
Command mode is the best solution if the user is
capable of editing or developing their own meter
reading software so that user can use Bluetooth Probe
for communication.
The C# code example for sending command is as
follows:
////==========================================
==============
//Initialize Probe at baudrate 300
buffer = new byte[] { 0xFE,0xFE, 0x42,0x4C,0x55,
0x45, 0x30, 0x38, 0x4E, 0x31, 0x30, 0xFF };
this.comport.Write(buffer, 0, buffer.Length);
Thread.Sleep(50);
////==========================================
==============
This command will change baud rate or data type.
Second char from last can vary so that user can send different commands to probe:
Data Type Settings Commands:
0x30 : 300 baud
0x31 : 600 baud
0x32 : 1200 baud
0x33: 2400 baud
0x34: 4800 baud
0x35: 9600 baud
0x36:19200 baud
0x37: 28800 baud (Available with v3 and
later designs)
0x38: 38400 baud (Available with v3 and
later designs)
0x40: 7E1 data type
0x41: 8N1 data type
0x42: 8E1 data type
0x43: 8O1 data type
0x50: Break State: Enter (Available with v3
and later designs)
0x51: Break State: Exit (Available with v3
and later designs)

Other Commands:
0xA0: Firmware Version Query
The rmware version information will be sent and data will be
terminated with 0x00 character.
0xA1: Battery Voltage Query (mV)
Battery voltage information will be sent and data will be
terminated with 0x00 character.
0xA2: Close Sleep Timer (10 seconds)
If there is no connection with the Bluetooth probe for more than
10 seconds, the port goes into sleep mode and power saving
mode will be on.When the Bluetooth connection is turned on, the
sleep mode will be off and the port will work as usual and user
operation is not affected by this process.
Conrmation information will be sent and data will be terminated
with 0x00 character.
0xC2: Shut Down The Probe
Using this command, the power can be turned off as if the optical
probe was closed by the power button.
0xC3: Auto Shutdown Timer Setting
A time interval between 0 to 254 seconds should be set (in HEX
format). If there is no communication with the probe after that
time interval, the device will be turned off (probe shuts down).
This can prevent the probes to be left forgotten with power on for
long time and consume battery.
The default value is 254 seconds. This feature can be disabled by
setting value 255.
After sending the command, conrmation information will be sent
and data will be terminated with character 0x00. Then the time
interval must be set. The next conrmation information will be
terminated with character 0x00 again.
0xD0: Probe Reading Sensitivity Setting
If user gets some meaningless or corrupted data while reading
the meter, it is possible to change the reading accuracy of the
probe and make special setting based on meter type to prevent
reections or light interferences.
A value between 0 to 255 should be set (in HEX format). As this
value increases, sensitivity of the probe decreases and light
reception capacity falls. The default value is 49 (0x31).
After sending the command, conrmation information will be
sent and data will be terminated with character 0x00. Then the
sensitivity value must be set. The next conrmation information
will be terminated with character 0x00 again.
The user can transmit any data and command to the optical
probe without any restrictions and can use the optical probe
at any desired data type and communication speed at any time.
The commands transmitted to the optical probe and the data
transmitted to the meter is always separated.
0xE0: Save Settings (available with v3 designs and later)
It is possible to save settings for following data Sleep Timer,Auto Power
seconds, Reading Sensitivity, Baud Rate and Data type. After sending
the command, conrmation information will be sent and data will be
terminated with character 0x00.All listed values are saved as it is set and
next time the device restarted they will be used based on saved values.
0xE1: Restore Factory Defaults ( available with v3 designs and later)
Command sets values as follows and saves them
• Sleep Timer: ON
• Auto Power Down Seconds : 254
• Reading Sensitivity: 49
• Baud Rate: 300
• Data Type: 7E1
After sending the command, conrmation information will be sent
and data will be terminated with character 0x00.

BATTERY STATUS
The probe gives a low battery warning via LEDs to warn the low battery status and remind user to recharge.When battery is low,«BT POW» LED turns
into RED and remains until it’s charged enough.
FIRMWARE UPGRADE
The probe has capability to upgrade rmware over Bluetooth connection.
This way the user can change the functionality of probe as well as can
get the latest updates. User may also ask for changes in functionality.
Here are some examples:
• Firmware upgrade for specic meter model and protocol
• Firmware upgrade to change from Command Mode and work in
another mode like IEC auto detection
• Firmware upgrade to put any feature that user needs
Firmware upgrade procedure needs specic rmware prepared by our
company and the rmware upgrade software abcZ software also developed
by our company.
In order to use the software, the specic rmware must be selected. After
selecting the rmware path by clicking «Select Path» button the rmware
will be ready to be loaded to the probe. The probe has protection time
window 10 seconds after the powered up so the process must be started
within 10 seconds after the probe is turned on.
User should select correct COM port and click “LOAD FW” button using
abcZ Software.The software will Show the percentage of process visually
in terms of number of sent data packages.Also power LED will blink RED
during operation.The process will take less than a minute and the probe
will be ready to use with new rmware after an automatic restart. Device
should not be powered off during update process.
If somehow the rmware upgrade process is interrupted and upload le
has failed, the probe will lose rmware and stay in bootloader mode. In
that case user can try upgrading the rmware again and this time should
mark the «Forced FW Load» check box.
