Mitsubishi LCD TV Monitor link cable??
Ive got a 37" Mitsubishi TV that has a "brainbox" that it connects to which controls the TV, and other devices you connect to it.
It communicates with the TV via 2 cables:
HDMI --male - male
"Monitor link cable" (rs-232) (female to female db-9)
I am wondering if this monitor link cable is a null-modem cable b/c I need to snake it through my wall and plan on making an ethernet conversion cable.
I have called the manufacturer & tweeter and they told me it was a "special" cable exclusive to the model of my TV. They also told me that the 25 ft. HDMI cable I got from Ebay for $30 was going to cost $400 thru them.
Anyone have any experience with this stuff? B/C in my A+ studying I've learned that female to female is always null modem. So I am confused.

RS-232 is an electrical standard has has nothing to do with the pin-out of the particular cable. If they won't give you the pin-outs, the only way to know for sure is to ring out the cable with an ohmmetter. the particular gender doesn't mean anything. Just because it is a sub d-9 doesn't mean anything.
In the world of A/V, cables are the greatest margin for profit of any item. That's why Monster cables are so ridiculously expensive and the salesguy at BestBuy is always trying to push them.

Best buy sells AV cables for $125... my supplier carries the exact same one for $20...On the road to Cisco. Will I hunt it, or will it hunt me? -

So I would measure resistance between cable end pin to cable end pin, correct?
One more question...Is it advisable to splice a serial cable by cutting & re-soldering & shrink wrapping the individual wires in the middle? (I know this may be a ridiculous question so go ahead & flame me if I am out of my mind in thinking that this will work
