Default GRT EIS-4000 in tandem seating

Hi there,

Is there anyone running dual GRT EIS-4000 units (Master and Slave).

I am wanting to locate a pin out diagram for the Slave unit and if there are any particular installation instructions or manual notes associated with the setup of the Slave.

I am guessing the Slave is setup from the factory and doesn't require much from the installer. Is there any separate manual?

Any info would be greatly appreciated.

Hi, I have not heard of the possibility of having dual EIS units. Before doing that, you might want to try the GRT Remote App.

https://grtavionics.com/miscellaneous-software/

Perhaps it can do what you need.

Another option would be a small EFIS, since it will show the data graphically.

I personally almost never use the EIS directly, but prefer to get the data from the EFIS.

Do you have a physical size constraint in the back seat?

Actually trying to troubleshoot a system already installed. It is the sole engine data provider, not what I would choose personally but it's there (clients aeroplane).

The second unit is labelled 'Slave', on a factory label, and only has one D-Sub socket on the back instead of the usual two.

Just after a pin out to check continuity really, not pin out of the Master unit (I have those as they are available on the GRT website) but the Slave.

I know that they exchange info via RS-232 so I'd expect to see 4 total wires used on the slave - RXD, TXD, 12v, Ground. You might want to drop a mail to the boys in Michigan (support@grtavionics.com) to help figure this one out.

Thanks, have done just that.

Was hoping to shortcut things if someone else had already been there, done that.

There are a lot of GRT gurus on VAF, so you might get an answer from one of them over the weekend. Best of luck with it!
