AGILENT FLM BOARD - G1321C G1321-65020

The AGILENT FLM board (detector main board) is the central control/processor assembly used in Agilent fluorescence detectors of the G1321 family (including G1321C) and is responsible for coordinating detector activities, communications and safety/diagnostic functions. It interfaces to the detector frontend, lamp and monochromator electronics, manages firmware/serial-number information, and provides the interface to host control systems for routine operation and service.

Key Features:

• Main processor: Motorola MC68332 running at 16 MHz; onboard memory includes 4 × 512 KB SRAM, 1 MB flash EEPROM and 128 KB battery-backed NV-RAM.
• 304‑pin application‑specific integrated circuit (ASIC) providing drivers and I/O for detector subsystems.
• Communications supported: Controller Area Network (CAN), GPIB, RS‑232C and LAN for instrument control and remote signals.
• Designed for use in Agilent G1321 fluorescence detectors (G1321C compatibility indicated in Agilent product listings).

Advantages:

• Consolidated control and diagnostics: central processor and ASIC enable board‑level troubleshooting, firmware updates, and re‑entry of serial/ID information after replacement, reducing service time.
• Standardized communications and I/O (CAN/GPIB/RS‑232/LAN) allow seamless integration with Agilent ChemStation and lab automation for reliable instrument control.
• Built‑in monitoring and safety support (lamp ignition/power regulation, fan monitoring and leak/temperature compensation) help protect detector optics and reduce unplanned downtime.
