1.4 DESCRIPTION OF THE TERMINAL
The digital weight indicator allows highly accurate and reliable
weighing. It is mainly designed to weigh vehicles and for
commercial weighing purposes. The graphic display and fully
alphanumeric keypad make it ideal for use by even inexpert
operators.
Some of the main features of the indicator and listed below:
facility for connection to a maximum of 2 scales with analogue
load cells (up to 24 x 350 ohm load cells)
facility for connection to a maximum of 2 scales with digital load
cells (up to 16 CPD load cells)
three RS232/422 serial ports
2 inputs and 2 outputs
110-240 VAC power supply
can be connected to the keyboard of a compatible external PC
Optional boards to interface the indicator and expand the system
