FXM-16A/PCIe
A single board has four RJ45 jacks, each of which can be converted via a special 4-way hub or
constructed by yourself to connect with 4 analog channels. See Figure 2-13 below for the structure
of the 4-way hub.

Step 3: Connect to the ringing current & battery feed power supply
Note: Skip this step if FXS (station module) is not used in the system.
If you are using the external ringing current & battery feed power supply from Synway, note that
the plug has a peculiar design for the prevention of improper insertion and extraction. The correct
way is to hold the plug body (not the locking ring, or it cannot be fully inserted) when inserting the
plug home into the socket, and to grasp the locking ring (not the plug body or the conductor) when
pulling the plug out from the socket. See Figure 2-14 below.
