The serial frames will consist of ASCII-Hex values according to the frame format
generated by the Bio-OCX controller (see
).
The
CFG-DB_EventsChannel
parameter is not applicable in this case, as TCP events
cannot be generated spontaneously (i.e. events will not be generated until the Host has
started the socket).
In contrast, it is possible to have an open TCP against a different computer to the one
declared as the Remote Host. Great care must be taken in this case, as there could be two
Hosts acting simultaneously on the FingerVein Online electronics.
6.1.3. Bio-OCX protocol via UDP
Finally, the Bio-OCX protocol is also available via a UDP Socket:
• Commands from the Host to the FingerVein Online electronics are transmitted via
the port chosen from the Host (
Local Port
of the Host). From a FingerVein
Online electronics viewpoint, this is the Remote Host Port that can be configured
(see
, parameter 7) and that is 0 by default (automatic
assignment).
• The frames are received at the FingerVein Online electronics via port 5500 (
Remote
Port
from the Host).
The frame format will be binary and will not have the
<STX>, <ETX>
delimiters.
The
CFG-DB_EventsChannel
parameter should take the
$07
value for the FingerVein
Online Electronics to spontaneously transmit Online frames through this channel.
6.1.4. KSP protocol via UDP
Finally, FingerVein Online electronics allows for work with the new
Kimaldi Stackable
Protocol
(KSP). KSP operates via another UDP Socket:
• Commands from the Host to the FingerVein Online electronics are always
transmitted via Host port 6001 and using Broadcast IP frames. This means that a
special frame format will be used that will allow us to specify the node at KSP
level.
• The frames are received at the FingerVein Online electronics via port 6000 (
Remote
Port
from the Host).
• One significant advantage in relation to the Bio-OCX protocol is that the Host may
receive all Online Event frames generated from any KSP mode via just one
Socket on port 6001. These frames also carry the address of the node to have
generated them.
There is an ActiveX control to interact with the FingerVein Online electronics via KSP.
Please see the corresponding manual for further details.
The
CFG-DB_EventsChannel
parameter should take the
$08
value for the FingerVein
Online Electronics to spontaneously transmit Online frames through this channel.
