Yes, the power strip as you call it is also a module. It is probably PC4 module. There is also a newer one called a PB4. It is an output module along with this it provides power to the buss to power the head unit and other modules. You can hook up all three of the power strips. In most cases you want to evenly distribute the power on the buss. The modules you have other than the head unit are low power. I would connect the head unit to a power strip and then that to you modules if you want. That will ensure you head unit has enough power. Another issue you might run into with SL1 modules is the inputs are not isolated from the buss. This may cause issues with pH and/or ORP readings using both modules. The SLX modules which is isolated replaced the SL1 module. The SL2 module is also isolated. The SL2 module pH will not go much below the pH of 6. So it would not do for a freshwater tank or in a calcium reactor. The SLX has a pH port and a port that is switchable between pH or ORP. All SL modules have a temp port and 2 switch inputs. If you use the salinity port on the SL2 module you need a temp probe on that module. Also if you download myReef and connect a computer with myReef running to the SID and then to the powered up system you can program the outputs and rename the modules and ports.
Ah ok. so they are all modules. So if you see my post above about the software issue, should the program open with nothing connected or do I have to have the SID connected with the head unit to the computer in order for the program to open?
I guess my best option is to try and locate a SLX or 2. I wanted to have a temp probe, PH probe (I am not sure what the ORP is yet and even google search I didn't fully understand it), salinity probe. I need to look at the manual and see what the switch ports are even for. I know you said you cut that one red/black harness to use it for the switch ports, but I am not sure what they are for. I will have to take some time tomorrow and look at the instructions and see what I can learn.
Thank you for all the help.
