4W Intercom Ports

The base station can connect to a 4-wire systems via the RJ-11 jack labeled “4 WIRE”. The pinout for this jack may be seen in figure 6-4. For a description of how to set up the 4 Wire Jack refer to intercom settings in this section. The 4 Wire jack is for balance input and output signals.

The CAN bus cable starts at the Frequency Manager and then proceeds to the first base station. From the first base station, the CAN bus daily chains though all the base stations, stop- ping finally at the Frequency Manager. Both base station RJ-45 CAN bus connectors are wired in parallel so it does not matter which jack is used for the input or output cable. See Figure 6-6 below for a sample routing of the CAN bus cable. NOTE: For clarity the power, interconnect, and TX/RX ca- bles are not shown in the figure.

Auxiliary port

This jack allows a balanced input auxiliary signal to be placed into the base station. It also allows a balanced output signal to be brought out of the base station. The input signal can be software selected to be local or global. A local input signal is

Relay

A software selectable relay closure is available at the base sta- tion. The relay is normally open. However the base station software options can be set so the relay closes when the beltpack’s “C” button is pushed. The relay schematic is shown in Figure 6-7.

CAN Bus

The CAN bus allows the connection of multiple base stations to a Frequency Manager. The Frequency Manager then can be use to set all the base stations to a frequency plan plus set a variety of other options on the base station. The base stations then can program their beltpacks via an over-the-air link. Thus a whole system can be set-up with only a few button presses at the frequency manager. Each frequency manager can control up to 10 base station.
