Architecture: 

This Software Device is instantiated from the LCU Server Framework lsf.
The sub-class <<SW Device>>atm10Server:lsfSERVER is composed of an instance of the serial communication class <<Serial Device>>mirror:lsfSERIAL.

The hardware is driven by the RS232 serial communication port /tyCo2 available on the LCU Transition Module. The protocol is ASCII, 9600 Baud, 8 data bits, 1 stop bit, daisy chained with address setting, no parity, no handshake.

The Software Device atm10Server provides the following Specific Commands for the control of the mirror:

• GETTILT and SETTILT: to set and get the Tilt angles and
• CENTER: to recenter the mirror
• POWER: to switch On/Off the power amplifiers

Commands SETTILT / GETTILT / CENTER

These 3 commands are transient instances resp. of the classes:
<<Control>>atm10GETTILT:lsfCOMMAND_HANDLER,
<<Control>>atm10SETTILT:lsfCOMMAND_HANDLER,
<<Control>>atm10CENTER:lsfCOMMAND_HANDLER,
<<Control>>atm10POWER:lsfCOMMAND_HANDLER.

They invoke the inherited methods lsfRS232::lsfSerialWrite() and lsfRS232::lsfSerialRead().

This device is intended to be used mainly for optical alignments, thus no active control is foreseen during observation.
