Hi there,
Hoping you good folks will be able to assist a complete newbe here.
I want to be able to switch 28 'devices' on/off remotely (from a control room in the same building/floor). Doing the rounds and manually switching on/off via the front panel is a pain. The 'device' has no IR - just Serial (RS232).
I envisage a daisy chain type of 'controller' with RS232 and twin Ethernet ports (for LoopIN and LoopOUT). This would be connected to each 'device' with a CAT5 cable looping from #device1 to #device2 to #device3 etc. etc.
In theory, this would then allow me to fire one single on/off command and all devices would then switch on/off. The 'controller' could be a PCB, enclosed product or whatever - I'm just hoping its cheap.
Question is:
1)...does such a product exist? Or am I dreaming?
2)...how could I 'tag' e.g. #deviceX so only it switches off whilst others remain on?
Thanks
