Philips Avalon FM20 / FM30 Fetal Monitor Network Card (LAN Interface) Parameters 

Basic Information

• Model: Philips Avalon FM20 (M2702A), FM30 (M2703A)
• LAN Interface Type: Optional integrated LAN/RS232 system interface module (Option J70, Part No. M2703-67501)
• Interface Standard: 10BASE-T Ethernet (IEEE 802.3)
• Speed & Duplex: 10 Mbps, Half-Duplex only (no auto-negotiation, no 100 Mbps support)
• Port: RJ45 female connector (rear panel)

Network Configuration

• IP Address Assignment:
  • Manual static IP configuration (via monitor setup menu)
  • Automatic via BOOTP (DHCP not natively supported; BOOTP server required for dynamic IP)
   
• Network Protocols:
  • TCP/IP (IPv4 only)
  • Connection Indication (CI) messages: Broadcast / Unicast modes (for OB TraceVue / IntelliSpace Perinatal)
   
• Supported Systems: IntelliSpace Perinatal (E.0+), OB TraceVue obstetric surveillance systems
• Dual Interface Support: LAN + isolated RS232 (MIB/IEEE 1073) for parallel EMR/monitoring system connection (read‑only via RS232)

Electrical & Safety

• Isolation: Fully galvanically isolated (medical-grade, compliant with IEC 60601‑1‑2:2014 / EN 60601‑1‑2:2015)
• EMC Compliance: IEC 60601‑1‑2, ICES‑003 (Canada)
• Power Consumption: < 60 W total monitor power (LAN module included)

Physical & Installation

• Connector: RJ45 (8P8C)
• Cable: Category 5e (Cat5e) or better twisted‑pair Ethernet cable
• Network Segment: Monitor and surveillance PC/server must be on the same local network segment (no routing across subnets by default)

Key Notes

• LAN is an optional upgrade (Option J70); not standard on base FM20/FM30 units.
• Fixed 10 Mbps half‑duplex: Network switch port must be manually forced to 10 Mbps / half‑duplex (auto‑negotiation disabled) to avoid link issues.
