Cards with relays are relatively loud. Switching the relays is clear to hear. Purely electronically working cards (open collector outputs) are completely silent. The disadvantage of these cards, for example 8255, ELV IO 88, Velleman K8055, is that they are build only for small voltage and small capacity. To control little 12 volts lights or LED's these "open collector" cards however are very well suitable. If you want to control 110V/220V devices you should use a card with appropriately strong relays, for example the Conrad serial card, Velleman K8056, ELV CSI 8 or a parallel card with strong relais. Or you have to connect a second relais (or thyristor / triac) that can switch the needed current. Parallel cards cannot become cascaded, that means max. 8 outputs are available. So if you want to control more than 8 outputs you should use a serial or a USB card. Parallel cards can have undefinied states of the outputs with power on until software starts. If you need short switching times, for example less than 0,1 second, you have to use a USB card! The data processing time for USB cards is around 1-5 miliseconds. With USB cards you can have program runs with 0,02 seconds impulse time. The 8 channel parallel and the 8255 cards can process data signals very fast, too. At the moment there is only support for use of inputs with the Velleman K8055 USB card, on other cards the inputs are not supported yet. It is possible to control more than 24 channels by installing the program Licht24 Pro twice (respectively in a seperate directory) and run two instances simultaneously. For example use 3x Conrad serial with the first instance on COM1, and use 3x Conrad serial with the second instance on COM2. We plan to release a version which supports 32 channels => Licht32 Pro. Please visit our website to familarize yourself about all our current products: http://www.bksoft.de The most important data files are in simple text format so you can also edit them with a editor. For example, open the file channel1.uhr or the licht24pro.ini with a editor. If you do any manual changes you have to reload the files with "Programs, Automatic timer, Reload now" or restart Licht24 Pro to take these changes affect. First create a backup of the files you want to change manually. If you have problems because some of your changes made are not correct just copy your backup files back or reinstall the program to get a clean installation again. The alarm lists files can be found in the main folder of Licht24 Pro: channel1.uhr up to channel24.uhr To copy the program of the automatic timer Channel1 into the automatic timer Channel2 first open the file channel1.uhr with the editor or a text program. Mark the desired entries with the mouse and copy them via the copy function of the editor's main menu to the clipboard. Now open the file channel2.uhr and paste the entries from the clipboard into the opened channel2.uhr file. Save the file channel2.uhr and run Licht24 Pro. If you save alarm lists they are stored in the subfolder alarms. Licht24 Pro always works with the files in the main directory, so when you load saved Settings1 all files are copied from the alarms/alarms_01 folder to the main directory. The sequence programs are stored also in the main folder of Licht24 Pro: prog1.txt bis prog99.txt The end values of each program are stored in the file steps.txt, row1 = end value program1, row2 = end value program2, and so on... You can edit these files in the editor, too. The speed is regulated with the rotary knob. The rotary knob can also be controlled with the keyboards arrow keys respectively with the Pos1 and End key, to this the knob must be active (click once on the knob so it is getting the focus). We suggest to open a new browser tab for every report. With a simple "refresh" of the website all reports are available very quick! 
Create a link to the file licht24pro.exe in the Windows autostart folder. If you have start problems with the serial port you can start Licht24 Pro with a command line parameter STARTDELAY=x (x in miliseconds delay). Example: "c:\program files\licht24pro\licht24pro.exe STARTDELAY=10000" does a start delay of 10 seconds. The inverted comma must be added because of the space between the parameter! With our tests with several Windows versions the installation and start of Licht24 Pro works without any problems. Because of the many different supported devices there is mostly a driver for that exactly card needed. If you get nevertheless a error message you should (re-)install the correct 32 or 64 bit driver. Drivers for Quancom, Deditec and ftd USB devices can be found in the Licht24 Pro installations directory or download it from the manufacter website. To avoid problems we suggest to NOT use relais boards with a converter. A serial card needs a real serial port. If there is no serial port available insert a PCI or PCMCIA COM card to your PC or just use a USB type relaiscard. If you discover a program error we try to fix this immediately.
