ECD-1: Reference Command Number (NM) 01390

It is similar to the concept of MSH-10 Message Control ID, but at the equipment command/response level. This number is generated by the originator of this command.

ECD-2: Remote Control Command (CWE) 01391

Definition: This field identifies the command that the component is to initiate. Refer to User-defined Table 0368 – Remote Control Command in Chapter 2C, Code Tables, for valid values. Refer to LECIS standard for details.

ECD-3: Response Required (ID) 01392

Definition: This field identifies the mode of synchronization that is to be used in relation to the execution of the command. "Y" (Yes) means that the response is required immediately after execution; "N" (No) response is not required at all. Refer to HL7 Table 0136 – Yes/no Indicator for valid values.

Attention: As of version 2.5 this fieldwas retained for backward compatibility only and withdrawn as of v2.7. The TQ data type was deprecated; see Chapter 2A, section 2.A.81.
