3 Operating Controls The TB8100 BSS has a number of hardware controls which are available to the user. These controls are located on the control panel, reciter and PMU. This chapter identifies and describes these controls.
3.1 Control Panel 3.1.1 Standard Control Panel The operating controls on the standard control panel allow some manual control of one or two1 base stations in a TB8100 BSS. These controls and their associated LED indicators are identified in Figure 3.1 below, and their functions are explained in the paragraphs which follow. Refer to “Connection” on page 99 for information on the connectors located on the control panel. Figure 3.
Speaker Button and LED The speaker button cycles the base station audio through three states. At power-on the speaker is off. Pressing the button once turns the speaker on, but leaves the audio gated (muted). Pressing the button a second time leaves the speaker on and ungates the audio (monitor mode). Pressing the button for a third time returns to the start of the sequence, with the speaker off.
Microphone Channel Button and LEDs The microphone channel button selects which base station (BS) the microphone is connected to. At power-on both base stations are selected. Pressing the button once will connect the microphone audio to base station 1. Pressing the button a second time will connect the audio to base station 2. Pressing the button for a third time returns to the start of the sequence, with the microphone audio connected to both base stations.
The green speaker LED is lit when the speaker is turned on. Receive LED The green receive LED is lit when a valid signal is received on the selected base station. Speaker The control panel is fitted with a 0.5W speaker. Audio from either base station can be connected to this speaker. Carrier Button and Transmit LED The carrier button is a momentary press switch. When held down, it keys the transmitter while disabling the 600: balanced and unbalanced line, and microphone audio.
Alarm LED The red alarm LED will flash at a rate of 2 to 5Hz when an alarm has been generated by any of the TB8100 BSS modules. It will continue to flash until the alarm is cancelled or the fault is fixed. Note that only those alarms which are enabled using the Service Kit (Configure > Alarms > Alarm Control) will cause this LED to flash. Refer to the Service Kit documentation for more information. Base Station 1 Select Button Pressing this button selects base station 1.
Indicator LEDs 3.2 The power LED and alarm LED behave in the same way as for the standard control panel. Refer to “Power Saving” on page 53 for information about the behaviour of the LEDs when in power saving mode. Reciter The only controls on the reciter are the rotary hex switch mounted on the front panel, and the indicator LEDs visible through a slot in the front panel. Figure 3.
3.3 PA The only controls on the PA are the indicator LEDs visible through a slot in the front panel. Figure 3.
3.4 PMU The only controls on the PMU are the on/off switches on the rear panel for the AC and DC modules, and the indicator LEDs visible through a slot in the front panel. Figure 3.6 Operating controls on the PMU rear view front view b b c AC module on/off switch c d d indicator LEDs DC module on/off switch AC Module On/Off Switch This switch turns the AC input to the PMU on and off. Note that this switch breaks only the phase circuit, not the neutral.
Indicator LEDs 36 These LEDs provide the following information about the state of the PMU: ■ steady green - the PMU is powered up ■ flashing green - the PMU has no application firmware loaded; you can use the Service Kit software to download the firmware ■ flashing red - one or more alarms have been generated; you can use the Service Kit software to find out more details about the alarms.
