View Full Version : 737NG OVH light switches and pmSystems
Hi,
Has anyone managed to wire the light switches in such a way that all lights work properly in FS9 ?
Your solution would be very much appreciated because I donot manage.
Kind regards
Tony

Hi Tony,
Which ones are you having trouble with? and what interface are you using?
cheers

Hi Peter,
Ive wired all switches of my 737NG OVH as per pmSystems.
Landing Lighs :
Retractable L & R : No reaction;
Fixed : OK, but no difference whether I switch L or R;
Runway Tunoff L&R: No reaction;
Taxi Light : OK
Logo Light : No reaction;
Position Strobe/steady/standby : only works when Logo Lights=on;
Anti Collision : Ok;
Wing : OK;
WheelWell : No reaction.
It looks as though FS9 does not accept / does not know all these settings.
Kind regards

Which aircraft are you using? Some of those lights are AC specific!
PMDG737-700 (Transavia with wings)

Ok the PMDG you may not have access to all those lights. They use proprietary offsets on a lot of stuff like that. Might be the problem. You may want to try loading the default panel with it and see what lights work from that panel. If you get them to work that way, use the FS offsets to turn them on and off.
OK Bob, I ll have a go at it.

Bob, or anyone, any chance you could remove some of the mystery of "offsets" for me. I read so much here about PM and offsets and it's all over my head! I can replicate any mechanical component I see but I know nothing of programming stuff. I might one day have the need to convert to PM, but I'm very reluctant to alter the simplicity of my current set-up. Not understanding the PC terminology and reading everybody elses difficulties with PM puts me off even more. I'm hoping the new FDT software is a good thing, can't wait to see it.

Hey Gwyn. You are making offsets something they are not. You are already using them! An offset is nothing more then a number assigned to a object to let you manipulate it. Example Landing Gear. It has an offset, one for up and one for down! Landing gear annunciators, one for on and one for off... Does that help at all? There is a list of them for FS in Peter Dowsons docs for FSUIPC.

Gwyn,
Think of an offset as being like a cell phone number, that an application external to FS, such as pmSystems, uses to "talk" with FS:
pmSystems: [dials offset for Nose Gear - 0-B-E-C]
FS: "You have reached the Nose Gear hot line, use your touch tone keys to set the nose gear position. To raise gear press 0. To lower gear press 1-6-3-8-3".
pmsystems: [presses 0]
FS: "The nose gear has been raised, have a good day".
Is also useful to think of Peter Dowson's documentation as a telephone directory. FS Yellow Pages :).
Regards,
Alan.

Ok, Ok... Well I am gona bite here....
If 0 is up, and 1 is down what is the 6-3-8-3". Options do?
Sorry, Just figured I would ask... Please don't shoot me?

It is part of it's address... How many 0s and 1s do you think are in there? 1000s! You need the entire addres to find the right place right?

The complete number sequence of 16383 is required to lower gear.
The analogy is not 100% accurate to current cell phone technology, but that is the nature of analogies, metaphors, parables, comparisons, similes, etc.

anything between 0 and 16383 is transit of the gear.....

If your gear hydraulics has failed, and you are manually cranking gear down - many older aircraft do not have pressurized gas or gravity-assist backup systems - value would start at 0 and gradually increase to 16383.
When value is around 8000 - and your arms are really aching from all that cranking - gear is partially (half) extended.
Tower: "Memphis Belle, be advised your nose gear does not appear to be down and locked ".
Memphis Belle: [heavy breathing] "Roger, we know. We are extending manually, down to 8192 at this time".
