Here are some excerpts from a Yaesu FAQ that discuss these codes...
8.) Q – DG-ID has been mentioned a lot so what is it and why is it being used?
A – DG-ID replaces the existing DSQ function. Some of the things that will be noticeable with DG-ID, is that you have a separate Rx and Tx selection. In addition, DG-ID will no longer have a ‘BREAK’ function, but DG-ID 00 is considered “off”. DG-ID codes range from 00 – 99.
9.) Q – Does this mean that DG-ID will be assigned on a per-channel basis?
A - DG-ID will still be a global setting because of the way that it can be used on a system. As an example, the local repeater might use DG-ID 71 to access it locally. But, if you want to access the two repeaters using IMRS the end user might use DG-ID 90. If it is part of a multi-repeater network and the user wishes to access them ALL then they might select DG-ID 99. For these reasons, it is set-up to be on a global basis and not a per-channel basis.
10.) Q – I now understand DG-ID, but what is DP-ID and what will it be used for in System Fusion II?
A – One of the features of the DR-2x will be a priority override or remote control of the repeater. To help keep these features secure, DP-ID will be used. It works as a unique identifier, that must be synchronized with the DR-2x, in order to allow that radio to be able to control the DR-2x remotely.
Hope this sheds some light.
