Relay Card Commander

Since Edition 3, Bromba's SDK BioIDENTICA FF is able to start arbitrary programs on successful recognition of a fingerprint. This can be utilized, e.g., to control a relay card within a PC based fingerprint access control system in such a way that the appropriate signal lamps and a door opener are activated if an authorized person desires admittance.
As relay card an eightfold card from Conrad Electronics (ext. link) is used. This card may be controlled via a serial RS 232 COM port of a PC. Even a USB converter is available, superseding a null modem cable where reasonable.
The control of the COM interface is performed by the executable RelayCardCommander.exe, which supports the most important functions of the relay card. Parametrization can be done directly via command line interface, batch file, Windows shortcut, a self-written program, or via BioIDENTICA FF. Initialization is done automatically with each call of RelayCardCommander.exe.
Parameters of RelayCardCommander.exe
-pCOMn Declaration of serial port, n = 1, 2, 3,...
-w:R1R2R3R4R5R6R7R8 Rn = 0 switches relay n off, Rn = 1 switches it on
-t:R1R2R3R4R5R6R7R8 Rn = 0 retains state of relay n, Rn = 1 toggles it
-s:R1R2R3R4R5R6R7R8 Rn = 0 retains state of relay n, Rn = 1 switches it on
-d:R1R2R3R4R5R6R7R8 Rn = 0 retains state of relay n, Rn = 1 switches it off
-b:Time Time specifies time in ms, after which the relay gets back to the previous state
Examples:
RelayCardCommander.exe -pCOM1 -t:10000000 -b:5000 toggles relay 1 via port COM1 and switches back to the previous state after 5 s. 
RelayCardCommander.exe -pCOM1 -w:00000001 switches off relay 1-7 permanently and activates relay 8.
If RelayCardCommander.exe is started without parameters, the usage is shown in a command line window.
Requirements
Relay Card: Conrad order number 967720 (obsolete), 197720 (24V) or 197730 (240V)
Software: Windows XP or newer with .NET Framework 2.0 or higher
Processor: x86 compatible
Serial interface or optionally USB converter Conrad 197257
Restrictions
To speed-up initialization, only one relay card in series is supported.
