Manual Datafox ZK-MasterIV
3.5.7.2 Configuration of an active connection
An active connection requires that the following parameters are set or configured in the ZK-MasterIV or
the application (DFComDLL.dll):
com.active
(0 = deaktiviert, 1 = aktiviert) Switching on/off the active connection.
com.notify
(0 = deaktiviert, 1 = aktiviert) Switching on/off the active data record message.
com.prio
(0 = höchste, 65535 = niedrigste) Priority of the event messages in the queue.
com.host
(0.0.0.0 bedeutet alle) Host to one connection should be produced.
com.port
Port to one connection should be produced.
com.retry
Number of the attempts for connection setup.
com.timeout
Time out, after the set number has failed because of connection setup attempts.
com.repeat
The time out if by successful message about present records these were not retrieved,
until a renewed message should be carried out.
com.alive
Time out, when the terminal diminishes an existing communication channel (connection
quit) if no Kommunikations takes place. The DLL must send, if a communication channel should
not be diminished, cyclically a Ping to the ZK-MasterIV.
The bus address of the DLL (for call of DFCComOpenIV) is firmly given with 31. The number of
at the same time existing connections is delimited per DLL instance to 50 connections.
Here you have to pay attention to the following value margins and default values:

system
