Front Panel
The front panel is mounted onto the subrack with two quick-release
fasteners. It incorporates the indicator LEDs, four-line LCD display, user
controls, an ambient temperature sensor, and cooling fans.
The indicator LEDS allow some monitoring of the operational status of the
base station. The user controls and display allow the technician to
configure the IP address of each module. Refer to “Front Panel” on page 47
for more information.
The base stations have different front panel ducting arrangements
depending on PA type and power. Front panels may not be interchange-
able.
The microphone input and speaker are not currently used.
Reciter The reciter module comprises the receiver, exciter and digital control
circuitry. The reciter provides the Ethernet interface and system inputs and
outputs.
Receiver modules (receive-only reciters) are not fitted with the transmit
circuitry or front panel SMA connectors, and are physically unable to
transmit.
A TN9275 gateway module is physically similar to a reciter but does not
have transmit or receive connectors.
