 |
|
Icom and their vendors state that the A210 com radio is a slide in
replacement for the A200 as long as you are not using the built in
intercom. However the A210 also outputs rs232 data on pin 1 of the card
edge connector and that pin is grounded to make the panel light work on
the A200. I can spend a lot of time trying to disconnect that pin and
hope nothing else gets interfered with in the tight space behind my
panel but I've been trying to determine if leaving that pin grounded
will actually harm the data output circuitry on the A210? I'm not likely
to ever use the data output but if someone knows that there is little
risk of leaving it grounded, I'd sure appreciate hearing about it.
thanks

It appears that Pin 1 on the A200 was
ground for the panel lighting.
The A210 Service Manual says the RS232
input/output is managed by an Analog Devices
ADM202. In the data sheet for this part
we find the statement:
[img]cid:.0[/img]
It appears that nothing untoward will
happen if you don't unground pin 1.

Many thanks Bob. Your post gave me the hint I needed to sleuth out the
|
rest of the story.
The standard card edge connector on my radio is different from the
schematic and board diagrams in the service manual that I have (with Feb
2008 addendum).
The data sheet for the ADM202 does indeed show continuous short circuit
as an absolute maximum condition but it also says "Exposure to
absolute maximum rating conditions for extended periods may
affect device reliability."
The icom manual shows a 1K resistor in series with the rs232 line out if
you fit the optional Dsub back panel to the radio. It shows no
connection to pin 2 for the standard card edge back panel but it does
show a 100R resistor to the separate data out jack. I was able to
confirm that my radio in fact has a 1K resistor in series with pin 2. So
I can interchange the A200 and A210 without modifying the aircraft tray
and without any worries since I'm not using the intercom function.
thanks again
Ken

repost with pin number 1 correction in last comment
(pin 2 ref. is corrected to pin 1)

Yes, but reliability only for that function which
takes a specialized GPS based mapping/data base
product . . . does anyone offer such a thing?
Not sure I'd want any 'automatic' gizmo twisting
my radio knobs anyhow.

Didn't see how the intercom function came into
consideration . . . are those two pins not limited
to panel lighting in the A200?

I don't expect to use the GPS data base either (nor do I know if it is
available) but strange things happen and I did not want to give icom any
excuses to void the warranty.
There is actually a warning on the icom site about changes in the
intercom and GPS connections on the A210. The vendor and icom both
mentioned intercom connection changes. I just didn't want steer anyone
wrong with my conclusion since some folks probably are using the
intercom function.
