;Steps for setting up the HL7 package. Version 1.5
|
|
;1) Create an entry in the HL7 APPLICATION PARAMETER file (771) called
|
|
; 'PACS GATEWAY' and set ACTIVE/INACTIVE field to ACTIVE.
|
|
;2) Create an entry in the HL7 NON-DHCP APPLICATION PARAMETER file (770)
|
|
; called 'PACS GATEWAY' and set DHCP APPLICATION field to 'PACS GATEWAY'
|
|
; (repoint to file 771).
|
|
;3) Set the Entry Action field of the RA SEND entry in the Protocol file
|
|
; (101) to call 'PACS GATEWAY
