737 Overhead function questions

Post by XAID104 »

Hello every one.

I have 3 questions for the forum:

1. After shut down using the battery switch some annunciators remain lit while in the software (FSX) are turned off. In order to turn them off I must unplug the USB which connects the overhead to the computer and the utility power 5V.
What can be happening?

2. If input/output scripts are not used where should I put the "//" in order to prevent conflicts?
Please present me with an example.

3. What is the difference between the OC4BAv4 and OC4BAv4P?

Thank you all.

1. All annunciators should normally go OFF. If not, it could be several things, but hard to tell as I do not know your hardware(Factory built OVH or self-built?) or
OCP4NGX driver and script version? PMDG 737 version?

2. to disable a Variable you need to decompile the script file (ssi) to a txt file and then modify the line where the Var is with a // (slash slash space) before the Var and then compile the txt file back to a ssi file.

3. ??

Hi Roar

1. The overhead is self built and the script is[OCP4NGXv4.6 ssi.] and the aircraft is  PMDG 737NGX SP1c on FSX/W7 and SIOC 703B22. 2. Thank you
3. Sorry, my mistake. I meant the difference between the scripts OCP4NGXv4.6 ssi and OCP4NGXv4.6P ssi.
By the way
4. I have the panel of Opencockpits,OVH Engine start [automatic return I see the scripts for the 2 servos[ Var.0126 eng 1 and 0133 eng2] but I don't see a scripts for the 2 ignition lever. Do they exist somewhere?I found in Opencockpits but is it possible to insert it somehow and which changes may I have to make?

Thank you

3: This is explained in the MUST README file that came with OC4BAv4.
4: ALl OVH functions are in the script.
Sorry for this short answer, but only OC4BAv5 is supported here now.
