Users Manual
Another important component on the Microprocessor Board is the lithium battery, which
continuously updates the RUSKA 7350's date and time, even when the unit is powered
down.
The Sensors, Front Panel, the pump expansion and compression limit switches
communicate with this board through cables. The Processor Board also supports the
RS-232 serial interface, which allows the user's computer to communicate with the
RUSKA 7350.
