6 System overview Welch Allyn Connectivity Server
Data interface provided by the Welch Allyn Connectivity
Server (WACS)
The WACS option to the Acuity Central Monitoring System is able to provide these data
interface options:
• HL7 (Health Level 7) Interface option
• Third-Party Data Stream Interface option (XML format)
Either WACS data interface option can include one or both of these distinct modules.
• Inbound HL7 ADT Data module: Admit/discharge/transfer (ADT) data from your CIS or
HIS to WACS. WACS uses the Acuity System network to send ADT information to the
Acuity Central Monitoring System for storage.
• Outbound HL7 Vital-sign Observations module: Numeric patient vital-sign
observations from WACS to your facility-controlled clinical or hospital information
system (CIS or HIS).
