connecting two dosers gen 1 to profilux 3.1n

hello
is it possible to connect two slave dosers to profilux 3.1 n without consuming all the S ports (meanwhile i have a powerbar that is connected to s1-s4 and dosing pump gen 1 t s5-s8).. where to plug the extra gen 1 doser...

thanks

You will need this expansion card to connect your second doser: https://store.aquariumcomputer.com/e...interface.html

Thanks for your replay.. there was no need to purchase another card.. i connected the two dosers together.. by confiuring one to s25-s28.. and the other from s29-s32.. and then connect one of them to profilux and tge second one to the first.. and it worked just fine..
