Firmware Description
The firmware of the instrument consists of two independent sections:
• a non-instrument specific section, called ‘resident system’,
• an instrument specific section, called ‘main system’.
Resident System
This resident section of the firmware is identical for all Agilent 1200 Series
modules. Its properties are:
• the complete communication capabilities (GPIB, CAN, LAN and RS-232C),
• memory management,
• ability to update the firmware of the ‘main system’.
Main System
Its properties are:
• the complete communication capabilities (GPIB, CAN, LAN and RS-232C),
• memory management,
• ability to update the firmware of the ‘resident system’.
In addition the main system comprises the instrument functions that are
divided into common functions like
• run synchronization via APG remote
• error handling,
• diagnostic functions, and so on,
or module specific functions like
• internal events such as metering device, gripper and needle movements,
