Greetings,

I am trying to duplicate a CANbus system here at the STAR experiment. We have
two distinct modules/controllers and chains.  We want to split off some Wiener
crates to form a third (to make life easier on some subsytem detectors).  It
would also give us a backup option!

We presently have two GreenSpring TIP810, which are VIP610 carrier boards. (6U
VME boards with 4IP and front I/O ribbon connections).  We use two processors,
one is a 162, and the other 167, otherwise things are pretty identical, except
for the numbers and kinds of Wiener crates on each chain.   For these systems we
run an old version of VxWorks 5.2 and an old version of EPICS 3.12-LBL.4 

I did get some information from TEWs regarding the TIP810-10 which replaces the 
Greenspring 810, and am anxious to order.  I wanted to get some expert advice
first.  

Would there be significant benefits to trying a "new" approach rather than
duplicate. This all seems like a quick and easy option but perhaps there are
others that we should be considering?  (For example other carrier boards, the
TIP816 etc.)

Thanks in advance
