This standard is designed to ensure the interchangeability of truck tractors and trailers of different authors among themselves.
We will be happy if you develop your tractors and trailers in accordance with this standard.

Only electric saddle connector
Dimensions:
11 blocks - truck and trailer width
8 blocks - max distance from saddle pin to rear of truck frame
8 blocks - min distance from the saddle pin to the rear wall of the tractor cab
6 blocks - max distance from pin to trailer front wall
9 blocks - min distance from the saddle pin to the low part of the trailer (for example, to the falling paws of the trailer)

Microcontrollers (optional)
Two microcontrollers are included that you can install to transfer data between the tractor and trailer. A tractor-mounted microcontroller is not necessary if you provide data transmission via a composite signal through the fifth wheel coupling connector.

These two universal controllers support the transmission of data both through the signals "on / off" and "number", and through a composite signal. In the properties of the microcontroller, you can select the operating mode. In any case, the transfer of data from the tractor to the controller in the trailer is via a composite signal.

In order not to install the controller in the tractor, you can apply a composite signal to the saddle with the following codes:
1 - left turn signal
2 - right turn signal
3 - brake light
4 - reverse
5 - marker lights
6 - parking brake
Numerical Signals:
1 - Brake
2 - Turning the wheels of the trailer
