FreeSpeak II Base rear connectors

The Base Station rear connectors are listed below.

Label	Connnector function
A	Power connector. Mains power lead with internal current converter.
B	Power connector. DC wallwart power lead (Part # 453G032, 12V DC, 60W). Use connector A or connector B or both to guard against power failure.
C	Grounding screw. When connecting the base to other systems, you must connect the grounding screw to a good earth in order to prevent audio problems.
D	Fiber connector to FS II splitter (Part # FSII-SPL). Used with Fiber module (Part # HLI-SMFO or MMFO)
E	RJ45 connector to transceiver ( FSII-TCVR-19, FSII-TCVR-24) or splitter.
F	Dect Sync. RJ45 connector to another Base Station. Can also be used to synchronize to other Clear-Com DECT devices or another DECT based system. In some cases you will need a cross-over cable instead of a standard cable. See Pinouts
G	XLR Partyline connectors (standard microphone cable). Note: If power is enabled on these ports the power operates across a pair of ports, A & B, C & D. See Powering your system. See Pinouts Be sure to null the ports whenever cabling arrangements are changed.
H	RJ45 connectors for 4-wire intercom. These ports can change pin polarity according to whether they are connecting to a matrix or another device. See Port Function .
I	XLR connector (standard microphone cable) for Program Feed input, typically from a mixing console or audio player. Adjust levels in Audio Settings/Program Input in the Base Station menus.
J	XLR connector (standard microphone cable) for Stage Announce output.
K	2 x RJ45 ports. These can be used for network connection or for daisy-chaining devices. Note: The ports share an IP address, so only one network connection is possible (either port can be used).
L	GPIO connector. See Pinouts .

Note:

For connection between the Base and transceiver/splitter and digital audio feeds, Clear-Com recommends shielded Cat 5/6 cable of no less than 24 AWG. Use of other cable can result in shorter cable runs and other performance problems.
