This section lists the available elementary functions that can be integrated into the customer’s
software for driving the ion source.
RS232 protocol
1. Baud rate: 115200
2. Parity check: no parity
3. Stop bit: 1 stop bit
4. Format: 8 bits
5. End of line character: <cr>
7.1 Starting up
Switch on the electronics rack. Wait about 30 seconds for microcontroller initialization.
Use the command « set rack_state 1 » to initialize the electronics cards inside the rack and start data
acquisition. It takes few seconds before the microcontroller returns the ACK character <cr>.
Set the current limits of the beam and focus high voltage power supplies by using the commands
« set imaxbeam <value> » and « set imaxfocus <value> » where <value> is the maximum allowed
supplied current. By default, these limits are set to 0 and no voltage is delivered by the HV power
supplies whatever the voltages set by the user.
Once it is done, the source is ready to be operated.
c
if the command « set rack_state 0 » is used or the rack switched off, the current limits
must be set again. These limits are used to detect short circuits, for more details see
the « HV security » part.
