1 — OVERVIEW
1 — OVERVIEW
e Curtis model 3301T is a highly congurable HMI that is suitable for demanding and cost-
sensitive applications. A color 3.5", 320 ×240 pixel high-brightness LCD allows vehicle operators to
view data in any lighting condition. An LCD heater is optional for operation in cold temperatures.
Vehicle operators use buttons to work with the user interface. e buttons make the 3301T ideal for
gloved operators and for applications that require precise tactile feedback.
e 3301T’s congurability allows various screen elements to be displayed. ese elements include
gauges, bar graphs, hour meters, warning icons, speedometers, and so on.
For example, the 3301T-7001 model provides two preset user interfaces: one for counterbalanced
forklis and the other for reach trucks and order pickers. For applications that require a tailor-made
user interface, the 3301T is easily customizable by Curtis engineers.
e 3301T provides four inputs that can be used as switch, analog resistive, analog voltage, and
frequency inputs. It also provides a pin that can be used for either a switch input or an output driver.
e 3301T also transmits and receives data over the CANbus.
