17.1 APPENDIX A – BALANCED AUDIO CONNECTION AND PINOUT
Balanced Audio connection diagram with balanced XLR for Analog audio input and output (Left+Right) and AES/EBU
digital audio input and output.
17.2 APPENDIX B – SERIAL CONNECTION E PINOUT
A standard Pin-to-Pin serial cable is required for the PC connection, not a CROSSOVER one. For a correct connection
the cable must not be more than 20 m long. Ports 2 and 3 use only the Tx, Rx and GND for the PC connection while port
1 also has the DTR (Data Terminal Ready) for modem connection. The port connection speed must coincide with the
speed of the port of the Macrotel X device and of the PC’s serial port.
