How can I control a Denkovi IP 8 relay board?

I am trying to control an "IP 8 Relay board" from Denkovi through MATLAB, but I can not find enough information about the instrucctions I need to programm it, all the examples I've found are from supported boards, like the Zed boards that can be programmed with the toolbox help.

I already have a network IP address for my board, as said on the manual.
