(SPES) – SPARC-II external speaker test
The SPARC-II connector is the middle D-SUB 15 female connector on the left rear side (see Section “Interface
connections” in the installation section). An external speaker can be connected to follow the Transceiver volume
setting. The speaker output is located on pins 11 and 12.

SPES-01 Activate voice receiver
E.g. by turning down squelch button or run
the alarm test from menu
5.4.
Pass:
Voice signal is
measured OK between pins
11 and 12.
Speaker output shall be controllable via the
transceiver volume control.
Fail:
No signal measured on
option pins 11 and 12.
NOTE:
Refer to the installation section for
connector pin ratings.

(SPMA) – SPARC-II microphone audio line input
The SPARC-II connector is the middle D-SUB 15 female connector on the left rear side (see Section “Interface
connections” in the installation section). The microphone line input in the SPARC-II connector contains the
microphone voice signal to transmit when operating the RT5022/RT5020 from a CU5000. The microphone input
line connects to the transceiver on pins 4 and 5.
To continue this test flow, you must verify you can establish a data connection on the SPARC-II bus. A CU5000
is needed to route the microphone audio to the baseband board via the.
