Update: found more information and got it work for my application.
Found a user review on the following site which pointed to a useful guide: http://www.banggood....i-p-925685.html

My application is a Rasp Pi 3 running OSMC. Set up the remote control in MyOSMC, remotes, as the RC-6. Then I went to Pi Settings and set Enable LIRC GPIO support as active and then set gpio_out to pin23 and gpio_in to pin 18, no other changes. Rebooted and it worked great. It took only a few minutes to set up in OSMC and didn't have to edit any config.txt files.
Very nice remote control with glow in the dark buttons
