Network Configuration; Master/Slave Operation - Techsphere VP-II X User Manual

USB Port
A USB port is available to be used for firmware upgrade or database backup.
Keypad
VP-II X keypad consists of 10 digit keys (0~9), an enter key (ENT), an escape key (ESC) and four
function keys (F1 ~ F4). Function keys are used for special purpose functions such as password
input, punch in/out or job code transfer for time and attendance, or Manager menu access. Function
keys are also used as arrow keys when accessing the Manager menu.
Hand Input Indicator
This is an LED indicating a User to place a hand.
Trigger Switch
VP-II X starts capturing the vascular data when this switch is triggered by a User. The trigger switch
is operational only when the hand input indicator LED is on.
Speaker
VP-II X has an internal speaker being used for beep and voice messages.
Handle
The handle guides a User's hand into a proper scanning position. It is required for a User to insert a
middle finger between the two guide bars until contact is made with the webbing in between your
fingers.

2. Network Configuration

VP-II X can be configured as a stand-alone unit or a networked system through a TCP/IP network. It is
required to set proper network parameters to run the VP-II X in a network environment. Refer to "Chapter
3 1 Network Setup" for details on network setup.

2.1 Master/Slave Operation

When multiple VP-II X units are networked, one unit has to be configured to a master unit while other
units are configured to slaves. A server on which the VP-II X application software (NetControl-X) runs
can be also configured as a master, in this case all VP-II X units are set to slaves.
Master
A master unit manages the site's entire network database. There must be only one master on each
network, which can be either a VP-II X or server. When there are more than 64 units of the VP-II X
running in the same network, a VP-II X cannot be a master and the server must be run as a master. A
VP-II X, when it is configured to a master, can only handle up to 63 slave units.
The VP-II X has to be configured to a master when it runs as a stand-alone. Factory default is set to
master.
Slave
The database of the slave units are synchronized with those of the master. Manager(s) can enrol/delete
Users on a slave, but the master unit must be available when enrolling or deleting a User as the slave
units are always referring to the database of the master. However, verification can be performed anytime
on any slave units without regard to the status of master unit.
