Twido OTB with Expansion Modules

Hello, I am using the Twido along with the OTB. My question is using output expansion modules on the OTB. I am using the Com Macro for my programing currently. I can only figure out how to work one output section at a time. Setting the address to 100 for the OTB outputs, or 101 for the output expansion module. For instance if I wanted to turn on all the outputs on at once, how would I go about that? I have tried subroutines to set the address to write to, and I couldn't get that to work. Do I have to use the exch commands? Appreciate the help.
