3.7 Remote Microphone Connections
Up to six optional QX-mini-RM Remote Microphones can be connected to each QX-mini. The
remote microphones communicate with the QX-mini through an RS-485 network bus. Power
for the remote microphones comes from the 24VDC terminal on the QX-mini main board.
The terminals and jumper on the QX-mini-RM board are shown in Figure 28 and are described
in Table 9.
