 		 #124341 - commercial device powered by RS232
Responding to: ???'s previous message
Joseph Hebert said:
but you won't find them offered by any reputable manufacturers


This morning I received an announcement for a new product line by a manufacturer I always considered to be "reputable".

See here: http://www.moxa.com/product/TCC-80.htm?Source=eDM

However these things are prepared to be powered by an external power source if the RS232-Port in use doesnt offer enough power itself.
