Hi,
I am trying to understand the significance of 120 ohm resistors at each
node of CAN network.
the network, Will I not end up hitting a 60 ohm ( 120 parallel 120)
with my signals instead of 120?
I know I could have got some basics wrong here but an explaination or a
pointer to some info would greatly help..

Thanks,
Vishal.

There is none --- because you're not supposed have one at each node.
You need them at the ends of the bus.

No. It's to impedance match the CAN bus cable with its end, to avoid
reflections. That's elementary wave mechanics, a.k.a. transmission
line theory (electronics 201 or so).

Do everybody including yourself a favour: get a textbook on CAN, and
work through it before you continue on this mission. www.can-cia.org
has recommendations.

Even if all the snow were burnt, ashes would remain.

Thanks. Will get a text book soon.
