NLX204 Info and Schematic Overview

Wires-X on XLX204 acts as an YSF Master, which provides 26 Wires-X rooms: 00001(=A) to 00026(=Z)

YSF and IMRS on fixed Module Y Module Y = Local onlyAMBE - also the default Wires-X entry room
XLX204 Wires-X Node Tx/Rx frequency is set to 434.412500 MHz

G3 Terminal Support for ICom-9700 and Icom Plus2 series on all Modules

All Modules A to Z are AMBE transcoded (6 simultaneous) D-Star ⇔ DMR/C4FM

Technical summary

The new generation XLX Reflector, written by Jean-Luc LX3JL (github.com/lx3jl/xlxd), support D-Start - DMR - C4FM (YSF & WiresX).
To make it fully - Multi Protocol - functional, hardware AMBE Vocoders need to be added. AMBE Vocoders translate audio AMBE+ (D-Star) to AMBE2+ (DMR/C4FM) and vise-versa. XLX204 has a number of AMBE-3003 Vocoders, so multiple Modules can be translated simultaneous.
When XLX Reflectors ars XLXinterLinked, each Reflector must have its own AMBE Vocoders to work fully Multi Mode on the interLinked module(s). AMBE+ and AMBE2+ is then broadcast on the interlink(s). This is the default behaviour by design. See XLX204 Modification.

Modification: The XLX204 xlxd software is modified to also transcode AMBE+ (D-Star) incomming XLXinterLink trafic.
By this change all other XLXinterLinked Reflectors (XLX007 - XLX088) don't need hardware AMBE Vocoders. XLX204 acts as a facilitating AMBE server on XLXinterLinked Modules.
See also How to connect in DMR and How to connect in C4FM.
Note: Only connect in Multi Mode on XLX204.
Interlinked Reflectors ( XLX007 - XLX088 ) are intended to be connected in D-Star only.
