ECD segment

The equipment command segment contains the information required to notify the receiving component what is to happen. 13.4.5.0 ECD Field Definitions 13.4.5.1 ECD-1 Reference Command Number (NM) 01390 Definition: This field contains the unique identifier for this particular command that should be used by the various components for future referral to this command. It is similar to the concept of MSH-10 "Message

required optional kept for older systems, still counted

Count the pipes to find a field, and count the empty ones too: an empty field still holds its place. Leave out the separator before ECD-2 and its value arrives as ECD-1, so the receiver stores Remote Control Command as Reference Command Number.

This page carries the ECD field table as published and nothing beyond it. The field notes, vendor behaviour, FHIR mapping and parsing guidance that thePID page has are still to be written for ECD.
