Controlling Stewart Screen and JVC Projecter with Simple Control

#1

I am upgrading an existing home theatre that was originally controlled with a philips pronto remote and a philips serial extender rfx 9600. The philips has ir, rs232 and relay outputs.

The screen is a ceiling mounted with a somfy controller (Part No. 1822163 6300891). The philips controls the screen via two relays. One for down and one for up. To switch to Simple Control will a simple blaster with the simple relay work?

The projector is a jvc dlahd1 controlled via an rs232. Will a simple blaster with the rs232 work with this projector.

Thanks. This is my first project with simple blaster.
