Path editor

23. Path editor

The Path editor is used for creating and editing the path buffer stored in the Setr.exe application. The contents of this buffer define the path to the node in the remote CU (Morse Communication Unit). By using command !p all service requests from Setr.exe will be directed to this CU. This enables remote configuring and diagnostics of such an CU that is temporarily or permanently unavailable for normal routing.

From MORSE main menu type p Enter.

23.1. Path packets and communication with remote stations

The simplest way of making a connection to a remote station is by using command !h with the address of the opposite station, e.g. !h690F0300. The pathway from the initial CU to the destination CU and back can be either trivial or goes through another CUs which provide for store-and-forward retranslation. All CUs concerned must have appropriate entries in their respective routing tables. It is then possible to send packets to this address or carry out path tests using command !.

The same result can be achieved by compiling short paths in the Path editor with the initial address on the first line and the destination address on the second line. The path is activated using command !p and thereby the path is set-up.

Between the initial address and destination address it is possible to add one or more addresses. The path between each neighbouring address pair must then be defined in the retranslation tables, i.e. from (1) to (2) and back, from (2) to (3) and back etc. Each of these added addresses becomes the destination address for the relevant section of the path packet and according to this address the path is searched in the retranslation tables. Therefore it is possible to create a new path combined from several sections, where each of these sections is defined in routing tables.

The route from the initial to destination CU or some of its sections can be created from direct defined steps without the need to use retranslation tables. If so the whole of this section has to be described in detail, which means that all steps must be there. Each step is labelled in the path editor with a label, which is a row of zeros inserted before the step address. The step address is then set according to the same standards that are valid for addresses in the routing tables. During the passage of a packet through a Node a path defined in such a way appears as follows: address 00000000 is found at the place of the next destination address, which means that the address of the next step is not searched for in the tables, but the following address in the path table is used, i.e. the address of the direct defined step. The resulting entry of the relevant section in the Path editor is now made up from the initial and destination addresses of the section, between which are written address pairs from which the first is 00000000 and the second is the address of the direct step.

With a !pxxxx command e.g. !p1401 it is possible to change the last address in the current path and thereby operatively change the destination of the path packet. This possibility is useful for creating variant paths, where their last section is found in the retranslation tables.

The Path packet in the whole listed range is functional from version 4.31.
