Additional information:

Each such device is shown as separate virtual com port (VCP) on your PC. The relay board outputs are controlled by FT245RL. It has 8 bit data output register (this device use only 4 of them). When data is sent to the register the outputs are set. If you are software developer - be sure "Synchronous Bit-Bang Mode" is selected! FTDI provides Bit-Bang Mode documentation. See this. The board can not be controlled directly via COM port - you need to download our DRM Software to control the device. The unit can not work without PC. Only one such device can be supplyed from single USB port. If you want to supply many such devices you need USB HUB with extra power supply.

DRM Software 

Denkovi Relay Manager (DRM) is universal software for controling all kinds of Denkovi USB, VCP and SNMP relay boards

 

DRM Software will hep you to save money for expensive softwares and time in programming. It allows you to switch ON/OFF your devices at particular date and time, turn ON/OFF the relays with pulses or control them via specific sequence. If you have one of our relay boards from this list you may turn your PC in powerful automation tool.
