RoIP: URI pin
Revision as of 08:29, 11 July 2014 by Onnowpurbo (talk | contribs)
Konektor URI adalah DB25, tampaknya tidak semua pin di perlukan, hanya sebagian yang di perlukan.
Pin yang di perlukan
- Pin 1 PTT
- Pin 9 MIC
- Pin 13 GND
- Pin 19 GND
- Pin 20 GND
- Pin 21 LINE (nampaknya ini lebih aman daripada MIC)
- Pin 22 OUT L
- Pin 23 OUT R
