Authorization Code Option
To provide a means of securing the VeriMed H2 Reader
against unauthorized use, an optional start-up
Authorization Code function is provided. This modality
consists of 8 entries of the two auxiliary buttons, F2 (left)
and F3 (right) in a predefined sequence. The factory
default setting is ‘disabled’, i.e. the unit will not prompt
the user to enter an Authorization Code, but rather will
immediately proceed to scan mode and establishing a
link with the host computer. This feature can be enabled
or disabled through the Configuration Mode (see
configuration mode section below).
If enabled, the Authorization Code is entered after the
Reader is turned on and self-tests are complete. The
user must press the two auxiliary buttons a total of 8
times in predefined sequence. This sequence can be
customized and stored in the EEPROM. The default
sequence (programmed at the time of manufacture) is:
F2,F2,F3,F3,F2,F3,F2,F3
Enabling Authorization Code
To enable authorization process, the user must send
the ‘?’ character from the HyperTerminal to the unit
via a serial link in Configuration Mode.
To disable authorization process, the user must send
the ‘!’ character from the HyperTerminal to the unit
via a serial link in Configuration Mode.
Changing the Authorization Code
To change this sequence, the user must power up the
unit and go into Configuration Mode. To enter the new
sequence, the user must send the ‘#’ character to the
VH2R over the serial link. Immediately after that the
unit will accept exactly 8 characters ‘l’ for F2 and ‘r’
for F1 (“l” for left and “r” for right button locations in
lowercase only) in the user defined sequence and the
new key is stored in the Reader EEPROM.
If the Code becomes lost, call customer service for
assistance.
If the key sequence is entered incorrectly, the unit
displays ‘ACCESS DENIED’ on the LCD and shuts
down after 1 second.
If the sequence is entered correctly, the unit
immediately tries connecting to the host according to
the set communication mode.
Configuration Mode
To operate in this mode the user should perform the
following actions:
• Connect the USB cable from the host computer to the
VH2R Reader.
• Turn on the VH2R Reader by pressing the F1 (large
center) and F2 button. The VH2R Reader will go through
its self-test procedure. Enter the Authorization sequence
as described later in this document if you are prompted
to “Enter Code” by the message on the unit’s LCD.
• Start the appropriate communication program on the
host computer system. For example, the user may
launch the HyperTerminal program and connect to the
serial port created by the USB driver. The VH2R reader
will stay in this idle mode for up to 5 minutes. The user
has two choices – to initiate a scan (normal operation)
or enter the configuration mode. If no choice is made
until the timeout, the unit will power down. The
communication program (HyperTerminal) should be set
to 9600 Baud, 8 data bits, one stop bit, no parity (8-N-1).
To enter the configuration mode, the user should send a
predetermined command from the host to VH2R (letter ‘c’
in lower case). The power down timer will be extended upon
receiving any character from the host system. When the
timer expires, the unit will power down. All configuration
settings are stored in non-volatile memory immediately
after they are entered. To exit the configuration mode, the
user can either use a special command from PC – letter ‘q’
in lower case (the VH2R will go into Idle mode), or press the
F1 button (the VH2R will enter scan mode).

VeriMed H2 Reader Communication
The unit has two communication devices – USB and Bluetooth.
Only one communication mode can be used at any time.
Both communication channels are bi-directional. When a
passive VeriMed Microtransponder is acquired by the
VH2R Reader, the ID number is sent to the host computer.
The host computer can also send certain information back
to the VH2R Reader. This feature is used to change current
configurations of the VH2R Reader, including possible a
switch between its communication modes (from USB to
BT and back) and utilizing the Authorization Code option.
VeriChip H2™ Reader Operation in USB Mode
To operate in this mode the user should perform the
following actions:
• Connect the USB cable from the host computer to the
VH2R Reader. The USB port is located in the rear of the
case. Lift the protective cover and insert the cable.
• To perform the scan, the user should press the F1
button once again. The VH2R will turn on the LF (low
frequency) interrogation field and try to acquire a
Microtransponder. The field will stay on for 12 seconds
or until a valid Microtransponder is acquired. If a
Microtransponder has not been acquired, the VH2R will
go into the idle mode. If a Microtransponder has been
acquired, its ID number will be displayed on VH2R LCD
and sent to the host computer via the USB interface.
After this the VH2R will enter its idle mode and be ready
for another scan session or power down after 5
minutes. The unit can be powered down from this state
by pressing the two smaller buttons (F2 and F3)
simultaneously.
Note: Operating in the USB mode, the unit does not monitor
the status of communication link. That is, if the USB cable
becomes disconnected, the user will not be notified. If the
cable was not connected to the host system, the latter may
not be able to open the serial port. Disconnecting the cable
during the communication session may produce an error on
the host system.
VeriChip H2 Reader Operation
in Bluetooth Master Mode
In the Master mode the VH2R performs the discovery and
then dials the host computer system acting as a Bluetooth
(BT) master. As a consequence, no action is required on the
Maintain a record of the Authorization Code for
future reference. Loss of Authorization Code
access will require a call to customer service.
