Description
Suntech ST20 is specifically designed for the ELD (Electronic Logging Device) ecosystem. It retrieves the vehicle information that is required by our ELD Compliance application partners through a direct connection to the vehicle with the appropriate harness (J1939/J1708). This required vehicle data is transmitted to the android device through the RS232 interface, which provides the data and charging connection.
