The Waters Bus SAT/IN Satellite Interface Module is an analog-to-digital converter that bridges Waters bus systems with satellite instruments, enabling bidirectional data transfer and control between the host computer and connected detector devices. The module translates analog signals from external instruments into digital data for processing by a host PC running Millennium software, requiring a Waters Bus LAC/E card installed in the host system.
Technical Specifications
• A/D Conversion: 10 MHz Voltage to Frequency converter with 8-bit BCD reader
• Signal Input Range: −0.25 V to 2.25 V
• Data Channels: Two independent A/D converters operating on two separate time bases
• Analog Cable Length: Maximum 2 m from detector to module
• Serial Cable Length: 4 m to 64 m from Bus LAC/E I/O Distribution Box
• Operating Temperature: 10 °C to 35 °C
• Relative Humidity: 20% to 80%, non-condensing
• Power Supply: Regulated table-model supply (sold separately)
– Key Features
• Two independent analog signal input connections for simultaneous multi-channel data acquisition
• Event input/output connectivity: two event input and two event output signal connections for trigger synchronization
• Optional BCD interface available as a separately ordered accessory
• Modular architecture supports up to four Bus SAT/IN modules per I/O Distribution Box for expanded channel capacity
• MMJ serial connector interface with six-connector cable for robust host communication
• Negligible vibration and shock sensitivity for stable laboratory operation
– Typical Applications
The module interfaces with analog detector systems in Waters chromatography platforms, translating detector output signals into digital formats compatible with Millennium software control and data logging. Event inputs accommodate trigger signals from Waters 715 UltraWISP and 717plus autosampler systems where applicable.
– Compatibility & Integration
Requires Waters Bus LAC/E card in host computer and regulated power supply (ordered separately). Connects via I/O Distribution Box using six-connector MMJ serial cable. Compatible with any device generating analog signals within the specified −0.25 V to 2.25 V input range.
