additional volume readout in the cab of your truck.
In addition to providing readout of the tank level, the S
provides a 4-20 mA analog output proportional to the fluid volume
displayed. This analog output can be used to communicate the tank
level to other pieces of equipment such as fleet management systems or
Electronic Logging Devices (ELD).
The full scale value of the analog output can be set using the buttons on
the back of the display, no additional equipment is required for calibration.
The S
L Access ™ also contains a serial RS-232 interface which

allows fleet management or ELD systems to gather fluid volume data from
the gauge. The interface is full duplex and contains security features to
prevent unauthorized access.
The S
L Access ™ display has been designed to withstand the
vibration and shock encountered in mobile applications. While the 808-
P2 and 810-PS2 operate on internal batteries, (12 volt truck power is used
