Common Configuration

Some aspects of a cascaded base system are common to both types of audio distribution. These include the

data cable connection and parts of the system configuration. Connect a data cable from the external control

connector of the Master to the Slaves (see wiring diagram on page 7). If there is only one Slave, a standard

Ethernet crossover cable may be used to connect the Master to Slave1. Note that the external port is an

RS422 serial connection not Ethernet. For this reason, an Ethernet hub cannot be used. It is important that

the correct number of Slaves be specified in the Master configuration. If this number is incorrect, the

system may not function correctly or may have degraded response times.

If a PC is going to be used for configuration, connect it to the Master base station. All Slave base settings

are accessible through the Master.

Once the connections are made, configure the receivers on each base and save the settings separately on

each base station. Then configure the transmitter and Beltpac settings at the Master base. Be sure to disable

the transmitters in the Slave(s) by turning them off in the Tx Power screen (see page 13). Do not make

Beltpac configuration changes at the Slaves, as they will be overwritten by the settings from the Master.

Once all settings are complete, save them again and upload them to the Beltpacs (from the Master base).

Then synchronize the settings from the Master (see page 24) and save the settings at the Slaves.

If paging will be used, connect the page outputs of each base to separate inputs on the paging amplifier and

connect page relays in series or parallel as required. If only Beltpacs on a single base will be allowed to

page, it is only necessary to connect that base to the paging amplifier.

Alert Relay Operation

Unlike the dedicated page relay, the alert relay is configurable for various functions. It can be configured to

signal an alarm when an undesirable condition exists such as high temperature in the base station or a low

battery in a Beltpac. It can also be used as a general purpose output controlled by a button on a Beltpac.

The relay can be enabled for any combination of these actions.

As an over temperature alarm, the relay is energized whenever the base station internal temperature exceeds

60°C. It remains energized until the temperature falls below 55° C. The base will not shut down automatically

due to over temperature conditions. However, operating the system above the specified ambient temperatures

may result in improper operation or damage.

When enabled to alert on low battery conditions, the relay will energize when any Beltpac reports a low battery

condition. It will remain energized until all Beltpacs report good battery voltage. Thus, even if the battery runs

down completely and the Beltpac stops operating, the alert condition will still exist until the battery is replaced

and that Beltpac resumes operation.

If a general purpose Beltpac triggered output is desired, the BP Button condition should be enabled. In this case,

the relay will energize whenever a user presses their alert button. The relay remains energized until the user

releases the button. As confirmation, the Beltpac user will hear the alert tone (if enabled) in the headset while

pressing the button.

NOTE: Beltpac firmware prior to version A.2.00 requires that the unit be in talk mode prior to pressing the

Alert button. Newer models do not have this requirement. Use PDA850 for Beltpac status, as shown on page 41.

The relay can also be enabled to signal fault conditions in the base. Faults of this type are catastrophic and

require cycling power or repair.
