Base Station Link

This pair of RJ-45 jacks allow the passage of WTA, WTA

termination control voltage, and CAN bus data between

multiple base stations. Up to eight (8) base stations may be

connected with the base station link. If just using WTA between

bases, up to 16 base stations can be connected together. The

pinout of the IN jack and OUT jack may be seen in Figure 27

and Figure 28

Stage Announce (SA)/Relay

The Stage Announce 3-pin XLR connector (see Figure 26) is

where audio exits the base when a beltpack user presses the SA

button. The pinout of the plug connector is shown in Figure 29.

Relay Output Schematic (Normally Open)

The stage announce output is balanced audio at line level. The

output level is configured in the software.

A relay contact closure also activates when a beltpack user

presses the SA button. The contacts are normally open (N.O.).

The relay schematic is shown in Figure 30. The rating of the

relay is 1 Amp at 24 volts AC or DC maximum.

A Phoenix type connector (supplied) plugs into the relay

contact port on the rear of the base station. This connector

provides a screw-type closure for an easy connection to wires.

See Figure 31.

40 Operation BTR-30N, TR-30N, TR-32N Connection of Multiple Base Stations with the Link Cables This section discusses various configurations of multiple base stations using link cables. Multiple base stations may be FIGURE 56. connected via standard 2-wire and 4-wire intercoms without additional link cables between them. They still transmit and receive intercom 1 and intercom 2 audio normally from the beltpacks.

46 Operation BTR-30N, TR-30N, TR-32N Wireless Talk-Around Audio Only These base stations are connected to share WTA channel 1 and WTA channel 2 audio but do not share the CAN bus data. If the WTA link cable passes from OUT to OUT or IN to IN, the WTA audio terminates in multiple places and causes the WTA audio levels to be greatly reduced/distorted. . Link Overview WTA 1 and WTA 2 in the BTR-30N are two (2) independent 2wire intercom channels.
PAGE 19
BTR-30N, TR-30N, TR-32N Do not set base stations to the base number 01 (Master), because CAN bus is connected to the other base stations with a BLC, as seen in Figure 65. If there are no masters on the CAN bus system, there is no activity on the CAN bus line and no need for terminations. IMPORTANT: The master base must always power-up after the servant bases in order to detect servant units to control.

BTR-30N, TR-30N, TR-32N 16. Cycle the power of the master base while leaving the single servant base powered-up. The master base, on boot, takes control of the servant base and assign it the base ID of 02 and turn its transmitters off. 17. If there are additional servant base stations to configure, turn off the master base station. 18. Power-up the next servant base station. 19. Repeat steps 10-12 and 16-18 for each additional servant base.

This could also be 4wire intercom via a matrix type wired system. 5. IMPORTANT: If using a party line to connect audio channels, the party line needs to be terminated by a connected PSU or a load XLR plug (P.N. TP-3 or TP-3R). See Figure 68. Connect the (BLC) Base Link Cable between base stations within a CAN network.
