D-STAR su Fusion DR-1X

In fase di progettazione l’Universal Digital Radio Controller. Il D-STAR sul DR-1X

 nwradio

La NW Digital Radio e John K7VE, stanno progettando un controller che permetterà di utilizzare il DR-1X sia in Fusion e Analogico, che in D-STAR. Questo controller si chiamerà UDRC. Nel frattempo K7VE ci spiega che è possibile collegare un modem GMSK D-STAR al DR-1X sfruttando la porta I/O.

Preparare il ripetitore DR-1X

Settarlo in modo che sia in modalità FIX FM in RX e TXFM-FM400

 Abilitare la funzione REMOTE

REMOTE400

 
  Il Connettore I/O del DR-1X

You will need to obtain a maleDB-15 HDplug and cover. If you are just prototyping and don’t want to solder up a connector, I recommend obtaining a breakout board.  I use a Winford EngineeringDB15HD Model (Male) with aM-F patch cable to go to the repeater. (Do not use a VGA cable, the lines must be straight through.)

The pins used are:

Pin Function
1 Remote Control Enable
2 PTT
5 Ground
6 Tone / GMSK In
8 Disc / GMSK Out
10 Ground
11 Ext Port 1

Modalità solo D-STAR

DR-1X Pin URI Pin Mini Din-6
1 20 2
2 Ext/GPIO 3
5 DR-1X (1) DR-1X (1)
6 22 4
8 21 1
10 DR-1X (11) DR-1X (11)
11 DR-1X (10) DR-1X (10)
  • Tie Pin 1 and GMSK (Audio – Pin 20 on URI, Pin 2 on Mini Din-6) ground to Pin 5.  This locks the repeater controller out and puts full control to the D-STAR modem/node adapter as the repeater controller.
  • Tie Pin 2 PTT to the PTT control (pull to ground) on your D-STAR modem/node adapter (URI will use an external device like a GPIO on a Raspberry Pi, Pin 3 Mini Din-6)
  • Tie Pin 6 GMSK IN to GMSK OUT from your D-STAR modem/node adapter (Pin 22 on a URI, Pin 4 Mini Din-6).
  • Tie Pin 8 DISC OUT to GMSK IN to your D-STAR modem/node adapter (Pin 21 on a URI, Pin 1 Min Din-6).
  • Tie Pin 11 to Pin 10.  This tells the repeater to stay in FM in / FM out mode full time.

Modalità D-STAR/Analogica

DR-1X Pin URI Pin Mini Din-6
1 Ext/GPIO 3
2 Ext/GPIO 3
5 20 2

8 21 1
10 DR-1X (11) DR-1X (11)

  • Tie Pin 1 Remote Control and 2 PTT to the PTT control (pull to ground) on your D-STAR modem/node adapter (URI will use an external device like a GPIO on a Raspberry Pi, Pin 3 Mini Din-6). This lets the Yaesu repeater controller handle analog when the PTT is high and puts full control to the D-STAR modem/node adapter as the repeater controller when the PTT is low.  Set a CTCSS tone in and out on the Yaesu controller but do not use 100 hz as the GMSK signal will periodically false the tone decoder.
  • Tie Pin 5 and GMSK (Audio – Pin 20 on URI, Pin 2 on Mini Din-6) ground.
  • Tie Pin 6 GMSK IN to GMSK OUT from your D-STAR modem/node adapter (Pin 22 on a URI, Pin 4 Mini Din-6).
  • Tie Pin 8 DISC OUT to GMSK IN to your D-STAR modem/node adapter (Pin 21 on a URI, Pin 1 Min Din-6).
  • Tie Pin 11 to Pin 10.  This tells the repeater to stay in FM in / FM out mode full time.
