Comen STAR8000C Patient Monitor Keypad To Alarm Indicator Board Wiring

Comen STAR8000C Patient Monitor Keypad To Alarm Indicator Board Wiring

Product Introduction

This twisted wiring harness acts as a dedicated internal signal link between the keypad module and alarm indicator board of the Comen STAR8000C multi-parameter patient monitor. It carries both keystroke command signals from the front operation panel and drive signals for the status indicator lights, ensuring every button input registers correctly and all visual alarm prompts activate as intended during clinical monitoring.

Specifications

• Compatible Device: Comen STAR8000C
• Application: Internal signal connection between front keypad module and alarm indicator circuit board
• Conductor Core: High-purity oxygen-free copper for low resistance, stable signal transmission
• Structural Design: Twisted-pair wiring layout to reduce internal electromagnetic crosstalk
• Insulation Jacket: Flexible flame retardant PVC with high bending resistance and anti-aging performance
• Connectors: Original-matching snap in terminals at both ends for secure, gap-free contact
• Auxiliary Feature: Position identification tag for fast, error free alignment during installation
• Operating Temperature Range: 0°C to 40°C, adapted to standard hospital ward environments

​Main Functions

First, it delivers keypad input signals from the front operation panel to the monitor’s indicator board and main control system. Every key press for parameter adjustment, alarm silence and menu navigation is transmitted accurately through this harness, ensuring immediate system response to clinical staff operations.

Second, it supplies stable drive signals to the alarm indicator board. Visual alert lights for high/low parameter alarms, system status and power state receive consistent control signals via this cable, so caregivers can identify equipment status at a glance from a distance.

Third, the twisted wire structure suppresses crosstalk between different signal lines, preventing false key triggers or flickering indicator lights caused by internal electromagnetic interference inside the monitor.

Precautions for Use

1. All installation and removal work must be performed with the monitor fully powered off. Live plugging and unplugging can generate current surges that damage the indicator board and keypad circuits.
2. Never pull the cable body directly when disconnecting the harness; always hold the plastic connector base to prevent internal wire breakage and bent terminal pins.
3. Avoid sharp bending, twisting or heavy compression of the cable during installation and daily use. Chronic stress on the same bend point will gradually crack the insulation and break inner copper strands.
4. Keep the harness away from high-heat components inside the monitor.
