6. Host communications
FingerVein Online electronics allows for several communication channels with the Host.
Establishing this communication is the first step towards correctly configuring the
electronics. FingerVein Online electronics is permanently listening to these channels and
will return a response via the channel from which the command was received.
We shall deal only with IP communications. For information on communications via RS-
232, please see
6.1. IP Communications
To access the IP communication services, the network parameters must be configured
correctly. Configuration can be carried out using the Bio-OCX protocol, via RS-232. In
this case, we shall deal with the parameters described in
. Alternatively,
the Kimaldi Localisation Service detailed below can be used. Once the equipment is
configured, there will be one TCP/IP Socket and two different protocols via UDP
Sockets.
6.1.1. Kimaldi Localisation Service
It is possible to detect the FingerVein Online electronics connected to your local area
network using the Kimaldi Localisation Service:
• IP configuration: once the unit is located from its MAC Address, it is possible to
configure its IP parameters and restart the unit.
• The localisation request from the Host to the FingerVein Online electronics is made
via port 2000.
• The frame reception in the Host from the FingerVein Online electronics is made
using port 2001.
There is a DLL that allows this Service to be integrated into any software application.
For further information on the low-level protocol, please see the
6.1.2. Bio-OCX protocol via TCP
The Bio-OCX protocol is also available via a TCP Socket, which makes it fully
compatible with the KiWi2 convertor module:
• FingerVein Online electronics is in server mode. Therefore, frames from any Host
can be accepted (please see
SLK-Safety
) The connection socket
will be started by the Host. FingerVein Online electronics will only generate TCP
events while this socket is enabled.
• Commands from the Host to the FingerVein Online electronics are transmitted
through an arbitrary Host port (
Local Port
of the Host).
• The frames are received at the FingerVein Online electronics via port 1001 (
Remote
Port
from the Host).
