Stage Connector
This supplies power to the stage and measures the temperature using platinum resistor sensors.
Instrument Bus
This connection is only used for the LNP95 Liquid Nitrogen Pump. If your stage has been supplied with an
LNP95 then a cable will have been provided which is used to connect the CSS450
to the LNP95.
It may be necessary to pull back the sprung mounted violet moulding towards the
cable before inserting the connector.
Expansion Boards
The CSS450 requires a motor expansion board, which requires the ’motor’ and ’sensor leads to be connected
correctly.
Any of the stages which use an expansion board will be marked with the same label as the CSS450 expansion
board.
External Input and Output Sockets
There are three 2.5mm jack sockets (6) on the rear of the CSS450 for synchronising or controlling external
equipment, see page 39 for the electrical specifications.
USB Connector
At present this is only used for updating the firmware in the CSS450 .
RS232 Connector
For a PC connection use the supplied RS232
crossover
cable.
