F.A.Q.
Q:- Does L4SC work with X-Plane?
A:- At the moment no, but we are working to run everything without doing anything. Our goal is that "L4SC user" can mount their "cabin" regardless of the simulator, and once completed you can change simulator without modification.
Q:- Does L4sc work with FS2004?
A:- No, only with FSX.
Q:- I have a IOCards based Overhead, what I need to configure and work with L4sc737Ovhd?
A:- You only need IOCard2Ovhd application, which you can find in the downloads section. It has a help document that explains how to use it (very easy, indeed).
Q:- I have a simcards based Overhead, what I need to configure and work with L4sc737Ovhd?
A:- Contact Sismo Solutions, they will provide the SC-Pascal script you needed.
Q:- I have an overhead based on another hardware, does it work with L4sc737Ovhd?
A:- At this time no, but you can send an email to

indicating what hardware you have. they explored all options.
Q:- I have no wired all the elements in my IOCard based overhead.Can I use it now?
A:- Yes, if these are not vital to the operation of aircraft. The setup application allows you to ignore those elements that do not have in your overhead.
Q:- I have a Master Caution Based on IOCards. What do I need to work with L4sc737Ovhd?
A:- In the download section you have a SIOC script, which only have to change inputs and outputs that correspond to your hardware.
Q:- I have a Master Caution based on simcards. What do I need to work with L4sc737Ovhd?
A:- Contact Sismo Solutions, they will provide the SC-Pascal script you needed.
Q:- I do not have a physical Master Caution. What can I use?
A:- In the download section, you have the L4sc G.C. MC, there are three gauges for Gauge Composer, one with the Master Caution Cap and FO all in one, another with the MC of the Cap and another with the MC of the FO. You can use as you want, together or separately.
Q:- Do I need G.C. Ovhd if I have a physical overhead?
A:- No, the G.C. Ovhd is needed only if you have no physical overhead.
Q:- When can I use the G.C. Ovhd?
A:- Only if you had no physical overhead, you can use the GC Ovhd to manage L4sc737Ovhd.
Q:- I have a physical overhead with L4sc compatible hardware, but I have no M.C. physical. Can I use the G.C. Master Caution?
A:- Yes, of course, and need not make any configuration in the GC master caution.
Q:- Do I need to L4sc737Ovhd is on the same computer as the MFS?
A:- No, you can run on any PC on the network. Thanks to uIocpPnp protocol is not necessary to configure anything. it will search and connect automatically to the simulator.
Q:- After 10 minutes of using the L4sc737Ovhd, the engines were stopped and fails to start.
A:- You're using L4SC737Ovhd in trial mode.
Q:- I have some solenoid selectors/switches for the functions of Start engines, wing anti-ice and yaw damper. Can L4SC737Ovhd manage them?
A:- Yes, L4sc737Ovhd is prepared to manage these elements. Contact

and will consider including it.
Q:- How do I use the L4sc737Ovhd?
A:- You must start with L4SC FSX aircraft, then launches L4SC737Ovhd, and then launches the script for your hardware or GC Ovhd. Then use the 737 procedures for starting and operating your simulator.
