1.4.4. Long Range equipment interface
The Long Range reply can be set in either:
F automatic mode (AUTO)
F manual mode L--3 ProTec (MANUAL)
F manual mode external application (EXT APPL).
The Long Range reply, when in AUTO mode, is made as soon as a request is re-
ceived on the Long Range communication port.
The Officer of the Watch must approve the Long Range replay when in MANUAL
mode, by a means of pressing a keyboard button on the L--3 ProTec before the re-
ply is performed.
The Long Range reply, when in EXT APPL mode, is made by the L--3 ProTec upon
reception of confirmation / acknowledgement from the external application via the
high--speed ports. The external application acknowledges the interrogation by re-
turning the LRF sentence (updated with reply information).
1.4.5. Long Range Input Data and Formats
The input data and formats are in the form of two Long Range interrogation sen-
tences, LRI and LRF, refer to Table 1--4.
F The LRI --sentence contains the information needed to determine if a reply
needs to be constructed.
F The LRF--sentence identifies the information items that are being re-
quested. Details of each sentence can be found in IEC 61162--1.
