				In my quest to find a small ethernet hub (for the two AFS units to  
 talk to each other) yesterday I discovered that the common Linksys  
 and Netgear models are 7.5V.  Should I be able to find a 12V hub?    
 If not, how do I step the voltage down?

				GRT recently shipped me a unit to connect my 3 GRT units.   It was a bit 
 pricey at $165.   I questioned whether I should be able to just go out 
 and find a hub for a better price.  They commented that this is an 
 'industrial' or 'commercial' grade product and that I might have a hard 
 time finding something equivalent.
 
 It's a EIBA5100T/R (DIN- rail mount) from Comtemporary Controls.  The 
 installation guides says "....hubs are designed for the Building 
 Automation Environment".  It has 5 ports, it s 3.5x3.31 by 1".  It can 
 be powered by AC 8-24V or DC 10-36V - no setup reuqired
 www.ccontrols.com
 
 Looks good to this builder.

 Hi Jeff,
 	If you only have two ethernet devices, you should be able to use an
 ethernet cross-over cable and have no need for a ethernet hub/switch.
 If you have 3 or more ethernet devices, you'll need a hub or switch.
 
 	Here is a link to a typical cross-over cable:
 <http://www.newegg.com/Product/Product.aspx?Item=N82E16812107216>
 
 	Here are lots more to choose from:
 <http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N 52810132%201230513960&bop=And&Order=RATING>
 
 	Here are lots of ethernet switches - One of them will likely run off
 12v directly:
 <http://www.newegg.com/Store/SubCategory.aspx?SubCategory=30&name=Switches>
 	Does AFS have any recommendations?  If you can use a direct cross-over
 cable, that would be best I think.

				A search through the AFS support forum turn up the recommendation of a 
 Linksys SD205 5 port switch.
 It is 12 volts and costs about $35.
 
 Here is the spec sheet.

				We have them on our website for $145 in the accessories section...same unit.
 
 They indeed are great little boxes that are very nicely built.  Industrial
 panel mount with metal enclosures.  It's what we've been installing for all
 the AFS or GRT panels we've been using.
 
 Cheers,
 Stein

				You could use a crossover cable (No hub required or the AFS units might automatically do the crossover function.  I would contact them before hunting for a hub.

				I have a 3500 and a 3400.  They just hooked together with a cable.  No 
 need for a hub.  I'd call AFS before I bought a hub.

				If your just linking 2 ea afs units then you can just use a Ethernet Cross
 over cable and will not need a hub.  If you want to connect more then 2
 devices then you will need a Ethernet switch/hib.
 
 If you want more info on a cross over cable shhot me a e-mail off list and I
 will assist you.
