Speedometer/Tachometer module
(1) Tachometer. (2) Pictograph symbol. (3) Speed readout. (4) Gear readout.
Speed readout (3) consists of three digits and the readout may show the machine ground speed in MPH (km/h). The main display module calculates speed by using the information from a frequency sensor input or the Cat Data Link. Illumination of the appropriate digits shows the speed. Gear readout (4) consists of two digits that show the transmission gear which is engaged. The left digit shows the actual gear, "1", "2", "3", etc. The right digit shows the direction that is selected, "F", "N" or "R". Tachometer (1) shows the engine speed in RPM. The engine speed is determined by the information that is sent to the main display module over the Cat Data Link. The engine speed is also determined from a frequency sensor input.
